I have a csv file that I load into an 11 column html table. The data displays as expected except there is a very narrow column on the far right. There is also an extra blank row at the bottom. I have made dozens of adjustments to the width percentages but the little column on the right prevails. I haven't tried to eliminate the extra row on the bottom because I don't know what to try. See CSS code.

One of the problems I was having was the java script, function drawOutput(lines) { and the codes that perform the function, generates the table and adds an extra blank row at the bottom, I guess waiting for another line of data. By adding one more line to the java script function code, the very last line, I was able to remove the extra empty row.
document.getElementById("output").appendChild(table).deleteRow(-1);
I have a few controls that I am attempting to encapsulate on my webpage. I have tried a few different methods on encapsulating my controls and they have not succeeded. I tried using a div and this did not work too well and I have also tried this post:
Create a group box around certain controls on a web form using CSS
What is happening is that a box is being created but it is at the top of my webpage instead of around the controls.
I would like to create a grey box similar to the ones found on this webpage:
https://img.labnol.org/di/trigger1.png
Below, I am attaching a copy of the CSS and HTML code that I am using in order to create my form. The form is a simple file upload form that I tweaked from an example. I am using this on my own, personal website.
Here is the HTML:
<!DOCTYPE html>

function uploadFile(){
var file = _("file1").files[0];
// alert(file.name+" | "+file.size+" | "+file.type);
var formdata = new FormData();
formdata.append("file1", file);
var ajax = new XMLHttpRequest();
ajax.upload.addEventListener("progress", progressHandler, false);
ajax.addEventListener("load", completeHandler, false);
ajax.addEventListener("error", errorHandler, false);
ajax.addEventListener("abort", abortHandler, false);
ajax.open("POST", "file_upload_parser.php");
ajax.send(formdata);
}
function progressHandler(event){
//_("loaded_n_total").innerHTML = "Uploaded "+event.loaded+" bytes of "+event.total;
var percent = (event.loaded / event.total) * 100;
_("progressBar").value = Math.round(percent);
_("status").innerHTML = Math.round(percent)+"% uploaded... please wait";
}
function completeHandler(event){
_("status").innerHTML = event.target.responseText;
_("progressBar").value = 0;
document.getElementById('p1').innerHTML = "Drag your file here or click in this area.";
}
function errorHandler(event){
_("status").innerHTML = "Upload Failed";
}
function abortHandler(event){
_("status").innerHTML = "Upload Aborted";
}
function changeText()
{
document.getElementById('p1').innerHTML = "1 file selected";
}

Coming back to the HTML, the fieldset tags are placed around the controls that I am attempting to encapsulate. I left them there so that anyone can see the main issue that I am running into.
I apologize but I am very new to web programming. Any help will be greatly appreciated, thank you.
Note: how the box is created doesn't really matter to me. I would expect that the box is created in HTML and then I can style it using CSS.
The structure of your HTML is fine, but the position: absolute properties in your CSS are clashing with the fieldset.
Since <fieldset> is wrapping all your controls, I would suggeset giving it a fixed width and height and position your child elements based on that, i.e. use width: 100% for your children and give all of them the same margin so they align nicely. Also make sure you either edit your #progressBar style in the markup.
Here's a snippet with the changes I just mentioned:
body {
background: rgba(0, 0, 0, 0.0);
}
fieldset {
width: 508px;
height: 270px;
/* fixed width and height*/
margin: 13vh auto;
}
#p1 {
border: 4px dashed #0D0D0D;
/* modified the actual text box instead of the entire form */
width: 508px;
height: 140px;
line-height: 140px;
margin-top: 0px;
}

text-align: center;

height: 140px;
margin: 22px 4px;

}

margin: 0;
color: #fff;
background: #16a085;
border: none;
width: 100%;
/* width relative to parent fieldset */

Is it possible to make a HTML5 slider with two input values, for example to select a price range? If so, how can it be done?
I've been looking for a lightweight, dependency free dual slider for some time (it seemed crazy to import jQuery just for this) and there don't seem to be many out there. I ended up modifying #Wildhoney's code a bit and really like it.
function getVals(){
// Get slider values
var parent = this.parentNode;
var slides = parent.getElementsByTagName("input");
var slide1 = parseFloat( slides[0].value );
var slide2 = parseFloat( slides[1].value );
// Neither slider will clip the other, so make sure we determine which is larger
if( slide1 > slide2 ){ var tmp = slide2; slide2 = slide1; slide1 = tmp; }
var displayElement = parent.getElementsByClassName("rangeValues")[0];
displayElement.innerHTML = slide1 + " - " + slide2;
}
window.onload = function(){
// Initialize Sliders
var sliderSections = document.getElementsByClassName("range-slider");
for( var x = 0; x < sliderSections.length; x++ ){
var sliders = sliderSections[x].getElementsByTagName("input");
for( var y = 0; y < sliders.length; y++ ){
if( sliders[y].type ==="range" ){
sliders[y].oninput = getVals;
// Manually trigger event first time to display values
sliders[y].oninput();
}
}
}
}
section.range-slider {
position: relative;
width: 200px;
height: 35px;
text-align: center;
}
section.range-slider input {
pointer-events: none;
position: absolute;
overflow: hidden;
left: 0;
top: 15px;
width: 200px;
outline: none;
height: 18px;
margin: 0;
padding: 0;
}
section.range-slider input::-webkit-slider-thumb {
pointer-events: all;
position: relative;
z-index: 1;
outline: 0;
}
section.range-slider input::-moz-range-thumb {
pointer-events: all;
position: relative;
z-index: 10;
-moz-appearance: none;
width: 9px;
}
section.range-slider input::-moz-range-track {

}

-moz-appearance: none;

border: 0;
}

<!-- This block can be reused as many times as needed -->
<section class="range-slider">
<span class="rangeValues"></span>

No, the HTML5 range input only accepts one input. I would recommend you to use something like the jQuery UI range slider for that task.
Coming late, but noUiSlider avoids having a jQuery-ui dependency, which the accepted answer does not. Its only "caveat" is IE support is for IE9 and newer, if legacy IE is a deal breaker for you.
It's also free, open source and can be used in commercial projects without restrictions.
Installation: Download noUiSlider, extract the CSS and JS file somewhere in your site file system, and then link to the CSS from head and to JS from body:
<!-- In <head> -->
<link href="nouislider.min.css" rel="stylesheet">
<!-- In <body> -->
<script src="nouislider.min.js"></script>
Example usage: Creates a slider which goes from 0 to 100, and starts set to 20-80.
HTML:
<div id="slider">
</div>
JS:
var slider = document.getElementById('slider');
noUiSlider.create(slider, {
start: [20, 80],
connect: true,
range: {
'min': 0,
'max': 100
}
});
Sure you can simply use two sliders overlaying each other and add a bit of javascript (actually not more than 5 lines) that the selectors are not exceeding the min/max values (like in #Garys) solution.
Attached you'll find a short snippet adapted from a current project including some CSS3 styling to show what you can do (webkit only). I also added some labels to display the selected values.
It uses JQuery but a vanillajs version is no magic though.
#Update: The code below was just a proof of concept. Due to many requests I've added a possible solution for Mozilla Firefox (without changing the original code). You may want to refractor the code below before using it.
(function() {
function addSeparator(nStr) {
nStr += '';
var x = nStr.split('.');
var x1 = x[0];
var x2 = x.length > 1 ? '.' + x[1] : '';
var rgx = /(\d+)(\d{3})/;
while (rgx.test(x1)) {
x1 = x1.replace(rgx, '$1' + '.' + '$2');
}
return x1 + x2;
}

Actually I used my script in html directly. But in javascript when you add oninput event listener for this event it gives the data automatically.You just need to assign the value as per your requirement.

The question was: "Is it possible to make a HTML5 slider with two input values, for example to select a price range? If so, how can it be done?"
In 2020 it is possible to create a fully accessible, native, non-jquery HTML5 slider with two thumbs for price ranges. If found this posted after I already created this solution and I thought that it would be nice to share my implementation here.
This implementation has been tested on mobile Chrome and Firefox (Android) and Chrome and Firefox (Linux). I am not sure about other platforms, but it should be quite good. I would love to get your feedback and improve this solution.
This solution allows multiple instances on one page and it consists of just two inputs (each) with descriptive labels for screen readers. You can set the thumb size in the amount of grid labels. Also, you can use touch, keyboard and mouse to interact with the slider. The value is updated during adjustment, due to the 'on input' event listener.
My first approach was to overlay the sliders and clip them. However, that resulted in complex code with a lot of browser dependencies. Then I recreated the solution with two sliders that were 'inline'. This is the solution you will find below.
var thumbsize = 14;
function draw(slider,splitvalue) {
/* set function vars */
var min = slider.querySelector('.min');
var max = slider.querySelector('.max');
var lower = slider.querySelector('.lower');
var upper = slider.querySelector('.upper');
var legend = slider.querySelector('.legend');
var thumbsize = parseInt(slider.getAttribute('data-thumbsize'));
var rangewidth = parseInt(slider.getAttribute('data-rangewidth'));
var rangemin = parseInt(slider.getAttribute('data-rangemin'));
var rangemax = parseInt(slider.getAttribute('data-rangemax'));
/* set min and max attributes */
min.setAttribute('max',splitvalue);
max.setAttribute('min',splitvalue);
/* set css */
min.style.width = parseInt(thumbsize + ((splitvalue - rangemin)/(rangemax - rangemin))*(rangewidth - (2*thumbsize)))+'px';
max.style.width = parseInt(thumbsize + ((rangemax - splitvalue)/(rangemax - rangemin))*(rangewidth - (2*thumbsize)))+'px';
min.style.left = '0px';
max.style.left = parseInt(min.style.width)+'px';
min.style.top = lower.offsetHeight+'px';
max.style.top = lower.offsetHeight+'px';
legend.style.marginTop = min.offsetHeight+'px';
slider.style.height = (lower.offsetHeight + min.offsetHeight + legend.offsetHeight)+'px';
/* correct for 1 off at the end */
if(max.value>(rangemax - 1)) max.setAttribute('data-value',rangemax);
/* write value and labels */
max.value = max.getAttribute('data-value');
min.value = min.getAttribute('data-value');
lower.innerHTML = min.getAttribute('data-value');
upper.innerHTML = max.getAttribute('data-value');
}
function init(slider) {
/* set function vars */
var min = slider.querySelector('.min');
var max = slider.querySelector('.max');
var rangemin = parseInt(min.getAttribute('min'));
var rangemax = parseInt(max.getAttribute('max'));
var avgvalue = (rangemin + rangemax)/2;
var legendnum = slider.getAttribute('data-legendnum');
/* set data-values */
min.setAttribute('data-value',rangemin);
max.setAttribute('data-value',rangemax);
/* set data vars */
slider.setAttribute('data-rangemin',rangemin);
slider.setAttribute('data-rangemax',rangemax);
slider.setAttribute('data-thumbsize',thumbsize);
slider.setAttribute('data-rangewidth',slider.offsetWidth);
/* write labels */
var lower = document.createElement('span');
var upper = document.createElement('span');
lower.classList.add('lower','value');
upper.classList.add('upper','value');
lower.appendChild(document.createTextNode(rangemin));
upper.appendChild(document.createTextNode(rangemax));
slider.insertBefore(lower,min.previousElementSibling);
slider.insertBefore(upper,min.previousElementSibling);
/* write legend */
var legend = document.createElement('div');
legend.classList.add('legend');
var legendvalues = [];
for (var i = 0; i < legendnum; i++) {
legendvalues[i] = document.createElement('div');
var val = Math.round(rangemin+(i/(legendnum-1))*(rangemax - rangemin));
legendvalues[i].appendChild(document.createTextNode(val));
legend.appendChild(legendvalues[i]);
}
slider.appendChild(legend);
/* draw */
draw(slider,avgvalue);
/* events */
min.addEventListener("input", function() {update(min);});
max.addEventListener("input", function() {update(max);});
}
function update(el){
/* set function vars */
var slider = el.parentElement;
var min = slider.querySelector('#min');
var max = slider.querySelector('#max');
var minvalue = Math.floor(min.value);
var maxvalue = Math.floor(max.value);
/* set inactive values before draw */
min.setAttribute('data-value',minvalue);
max.setAttribute('data-value',maxvalue);
var avgvalue = (minvalue + maxvalue)/2;
/* draw */
draw(slider,avgvalue);
}
var sliders = document.querySelectorAll('.min-max-slider');
sliders.forEach( function(slider) {
init(slider);
});

Note that you should keep the step size to 1 to prevent the values to change due to redraws/redraw bugs.

2022 - Accessible solution - 30 second solution to implement
This solution builds off of this answer by #JoostS. Accessibility is something none of the answers have focused on and that is a problem, so I built off of the above answer by making it more accessible & extensible since it had some flaws.
Usage is very simple:
Use the CDN or host the script locally: https://cdn.jsdelivr.net/gh/maxshuty/accessible-web-components/dist/simpleRange.min.js
Add this element to your template or HTML: <range-selector min-range="0" max-range="1000" />
Hook into it by listening for the range-changed event (or whatever event-name-to-emit-on-change you pass in)
That's it. View the full demo here. You can easily customize it by simply applying attributes like inputs-for-labels to use inputs instead of labels, slider-color to adjust the color, and so much more!
Here is a fiddle:
window.addEventListener('range-changed', (e) => {console.log(`Range changed for: ${e.detail.sliderId}. Min/Max range values are available in this object too`)})
<script src="https://cdn.jsdelivr.net/gh/maxshuty/accessible-web-components#latest/dist/simpleRange.min.js"></script>
<div>
<range-selector
id="rangeSelector1"
min-label="Minimum"
max-label="Maximum"
min-range="1000"
max-range="2022"
number-of-legend-items-to-show="6"
/>
</div>
<div>
<range-selector
id="rangeSelector1"
min-label="Minimum"
max-label="Maximum"
min-range="1"
max-range="500"
number-of-legend-items-to-show="3"
inputs-for-labels
/>
</div>
<div>
<range-selector
id="rangeSelector2"
min-label="Minimum"
max-label="Maximum"
min-range="1000"
max-range="2022"
number-of-legend-items-to-show="3"
slider-color="#6b5b95"
/>
</div>
<div>
<range-selector
id="rangeSelector3"
min-label="Minimum"
max-label="Maximum"
min-range="1000"
max-range="2022"
hide-label
hide-legend
/>
</div>
I decided to address the issues of the linked answer like the labels using display: none (bad for a11y), no visual focus on the slider, etc., and improve the code by cleaning up event listeners and making it much more dynamic and extensible.
I created this tiny library with many options to customize colors, event names, easily hook into it, make the accessible labels i18n capable and much more. Here it is in a fiddle if you want to play around.
You can easily customize the number of legend items it shows, hide or show the labels and legend, and customize the colors of everything, including the focus color like this.
Example using several of the props:
<range-selector
min-label="i18n Minimum Range"
max-label="i18n Maximum Range"
min-range="5"
max-range="555"
number-of-legend-items-to-show="6"
event-name-to-emit-on-change="my-custom-range-changed-event"
slider-color="orange"
circle-color="#f7cac9"
circle-border-color="#083535"
circle-focus-border-color="#3ec400"
/>
Then in your script:
window.addEventListener('my-custom-range-changed-event', (e) => { const data = e.detail; });
Finally if you see that this is missing something that you need I made it very easy to customize this library.
Simply copy this file and at the top you can see cssHelpers and constants objects that contain most of the variables you would likely want to further customize.
Since I built this with a Native Web Component I have taken advantage of disconnectedCallback and other hooks to clean up event listeners and set things up.

I am able to create a pie chart using Chart.JS with this code:
HTML
<div>
<canvas id="top10ItemsChart" style="padding-left:20px" width="320" height="320"></canvas>
<div id="top10Legend" class="chart-legend"></div>
</div>
jQuery
var data = [{
value: 2755,
color: "#FFE135",
label: "Bananas"
}, {
value: 2256,
color: "#3B5323",
label: "Lettuce, Romaine"
}, {
value: 1637,
color: "#fc6c85",
label: "Melons, Watermelon"
}, {
value: 1608,
color: "#ffec89",
label: "Pineapple"
}, {
value: 1603,
color: "#021c3d",
label: "Berries"
}, {
value: 1433,
color: "#3B5323",
label: "Lettuce, Spring Mix"
}, {
value: 1207,
color: "#046b00",
label: "Broccoli"
}, {
value: 1076,
color: "#cef45a",
label: "Melons, Honeydew"
}, {
value: 1056,
color: "#421C52",
label: "Grapes"
}, {
value: 1048,
color: "#FEA620",
label: "Melons, Cantaloupe"
}];
var optionsPie = {
legend: {
display: true,
position: 'right',
labels: {
fontColor: 'rgb(255, 99, 132)'
}
}
}
var ctx = $("#top10ItemsChart").get(0).getContext("2d");
var top10PieChart = new Chart(ctx).Pie(data, optionsPie);
document.getElementById('top10Legend').innerHTML = top10PieChart.generateLegend();
The problem is that it positions the legend to the bottom of the pie, and even spilling and bleeding outside of the boundaries of the div to which I want the pie to restrict itself:
It also presents the legend as a simple unordered list. What I want to do is to control the color of the various elements in the legend ("Banana" should be the same color (#FFE135) as the piece of banana pie (so to speak), etc.)
How can I make the individual elements match the color of its respective data point?
UPDATE
The "Legend Label Configuration" topic in the official docs here indicate you can set the fontColor of the legends, but this is for the whole shebang; what I want to know is, how is it possible to control the color of each item?
UPDATE 2
In an attempt to at least get the legend displaying in the desired spot, I added this to the jQuery:
var optionsPie = {
legend: {
display: true,
position: 'right',
labels: {
fontColor: 'rgb(255, 99, 132)'
}
}
}
. . .
var myPieChart = new Chart(ctx).Pie(data, optionsPie);
document.getElementById("legendDiv").innerHTML = myPieChart.generateLegend();
...but it makes no difference - the legend is still hung from the bottom of the pie chart, and its font is still the default black.
UPDATE 3
I utilized some suggested code, but the legend is still gravity-fed instead of hanging off to the right:
So the legend impinges on the chart below it, rather than restricting itself to its own neighborhood.
Also, I don't want the bullet points to infest the legend - the colored squares (and the verbiage - but also the values) are all I need. How can I shove the legend from south of the pie to east of the pie?
UPDATE 4
I have refactored the code based on this and it's looking better (I added more data to the "label" value of the data array, too):
Still, though, as you can see the legend is infringing on the quadrant below it. There is a "ton" of empty/wasted space around the pie, though - I want to move the pie to the left, and the legend to the right of the pie. That would also allow more vertical space for the pie to grow in stature.
How can I do that? Here is the code I'm using now:
HTML
<div>
<canvas id="top10ItemsChart" class="pie" style="padding-left:20px"></canvas>
<div id="top10Legend"></div>
</div>
CSS
.pie-legend {
list-style: none;
margin: 0;
padding: 0;
}
.pie-legend span {
display: inline-block;
width: 14px;
height: 14px;
border-radius: 100%;
margin-right: 16px;
margin-bottom: -2px;
}
.pie-legend li {
margin-bottom: 10px;
display: inline-block;
margin-right: 10px;
}
JQUERY
var data = [{
value: 2755,
color: "#FFE135",
label: "Bananas: 2,755 (18%)"
}, {
. . .
}, {
value: 1048,
color: "#FEA620",
label: "Melons, Cantaloupe: 1,048 (7%)"
}];
var optionsPie = {
responsive: true,
scaleBeginAtZero: true,
legendTemplate: "<ul class=\"<%=name.toLowerCase()%>-legend\"><% for (var i=0; i<segments.length; i++){%><li><span style=\"background-color:<%=segments[i].fillColor%>\"></span><%if(segments[i].label){%><%=segments[i].label%><%}%></li><%}%></ul>"
}
var ctx = $("#top10ItemsChart").get(0).getContext("2d");
var top10PieChart = new Chart(ctx).Pie(data, optionsPie);
$("#top10Legend").html(top10PieChart.generateLegend());
NOTE: Adding this to optionsPie:
legend: {
display: true,
position: 'right'
},
...does nothing - the legend remains weighted down to the floor like a frog filled to the chin with quail shot.
UPDATE 5
I've played around with Teo's example, trying to get it to work just right but, although it's better, the pie is very puny, and the legend should be wider, but I can't figure out how to stretch the legend horizontally and the pie in all directions. Here's how it looks now:
This is the code now (JQUERY is the same):
HTML
<div class="col-md-6">
<div class="topleft">
<h2 class="sectiontext">Top 10 Items</h2>
<br />
<div class="legendTable">
<div class="legendCell">
<canvas id="top10ItemsChart" class="pie" style="padding-left:20px"></canvas>
</div>
<div class="legendCell" id="top10Legend">
</div>
</div>
</div>
</div>
CSS
.topleft {
margin-top: -4px;
margin-left: 16px;
margin-bottom: 16px;
padding: 16px;
border: 1px solid black;
}
canvas {
width: 100% !important;
height: auto !important;
}
.legendTable {
border: 1px solid forestgreen;
display: table;
width: 100%;
table-layout: fixed;
}
.legendCell {
display: table-cell;
vertical-align: middle;
}
.pie-legend ul {
list-style: none;
margin: 0;
padding: 0;
width: 300px;
}
.pie-legend span {
display: inline-block;
width: 14px;
height: 12px;
border-radius: 100%;
margin-right: 4px;
margin-bottom: -2px;
}
.pie-legend li {
margin-bottom: 4px;
display: inline-block;
margin-right: 4px;
}
Something is squashing the pie and pushing the outer edges of the legend together.
UPDATE 6
Ochi, et al: Here's what I see after the Ochification of my code:
This is my code - I even ordered the jQuery in the way you have it, although I doubt that is really necessary:
HTML
<div class="row" id="top10Items">
<div class="col-md-6">
<div class="topleft">
<h2 class="sectiontext">Top 10 Items</h2>
<br />
#*<div class="legendTable">
<div class="legendCell">
<canvas id="top10ItemsChart" class="pie" style="padding-left:20px"></canvas>
</div>
<div class="legendCell" id="top10Legend">
</div>
</div>*#
<div class="chart">
<canvas id="top10ItemsChart" class="pie"></canvas>
<div id="pie_legend"></div>
</div>
</div>
</div>
. . .
</div>
CSS
.pie-legend {
list-style: none;
margin: 0;
padding: 0;
}
.pie-legend span {
display: inline-block;
width: 14px;
height: 14px;
border-radius: 100%;
margin-right: 16px;
margin-bottom: -2px;
}
.pie-legend li {
margin-bottom: 10px;
display: block;
margin-right: 10px;
}
.chart,
#priceComplianceBarChart,
#pie_legend {
display: inline-flex;
padding: 0;
margin: 0;
}
JQUERY
var optionsPie = {
responsive: true,
scaleBeginAtZero: true,
legendTemplate: "<ul class=\"<%=name.toLowerCase()%>-legend\"><% for (var i=0; i<segments.length; i++){%><li><span style=\"background-color:<%=segments[i].fillColor%>\"></span><%if(segments[i].label){%><%=segments[i].label%><%}%></li><%}%></ul>"
}
var ctx = $("#top10ItemsChart").get(0).getContext("2d");
var data = [{
value: 2755,
color: "#FFE135",
label: "Bananas: 2,755 (18%)"
. . .
}, {
value: 1048,
color: "#FEA620",
label: "Melons, Cantaloupe: 1,048 (7%)"
}];
var top10PieChart = new Chart(ctx).Pie(data, optionsPie);
$("#pie_legend").html(top10PieChart.generateLegend());
...and yet the pie is stretchier than stretch pants on an elephant.
UPDATE 7
Maybe there's a configuration problem or something. I decided to "upgrade" to version 2.1.3 of Chart.JS (started out w. version 1.0.2):
#*<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/1.0.2/Chart.min.js"></script>*#
<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.1.3/Chart.js"></script>
...and copied almost exactly Teo Dragovic's CodePen here.
The only things I changed were the names of two CSS class ("table" became "legendTable" and "cell" became "legendCell") and the color of the table border from red to forestgreen, and I get this now:
Do I need to also a reference a Chart.JS CSS file or something?
I think this what you want: DEMO
First, you need to make canvas responsive by overriding fixed width and height and wrap it in additional div that can be used for positioning. I used display: table for centering elements but setting inner divs to inline-block also works if you wish for chart and legend to take different amount of space than 50:50.
HTML:
<div class="table">
<div class="cell">
<canvas id="top10ItemsChart" class="pie"></canvas>
</div>
<div class="cell" id="top10Legend"></div>
</div>
CSS:
canvas {
width: 100% !important;
height: auto !important;
}
.table {
border: 1px solid red;
display: table;
width: 100%;
table-layout: fixed;
}
.cell {
display: table-cell;
vertical-align: middle;
}
UPDATE: Did some adjustment based on additional information by OP NEW DEMO
HTML:
<div class="container">
<div class="row">
<div class="col-md-6">
<div class="topleft">
<h2 class="sectiontext">Top 10 Items</h2>
<br />
<div class="chart">
<div class="pie">
<canvas id="top10ItemsChart" class="pie"></canvas>
</div>
<div class="legend" id="top10Legend">
</div>
</div>
</div>
</div>
</div>
</div>
CSS:
.topleft {
margin-top: -4px;
margin-left: 16px;
margin-bottom: 16px;
padding: 16px;
border: 1px solid black;
}
canvas {
width: 100% !important;
height: auto !important;
margin-left: -25%;
}
.chart {
border: 1px solid forestgreen;
width: 100%;
overflow: hidden;
position: relative;
}
.pie {
position: relative;
padding: 10px 0;
// adjust as necessary
padding-left: 10px;
padding-right: 0;
}
.legend {
position: absolute;
right: 10px;
top: 10px;
height: 100%;
// adjust as necessary:
width: 48%;
}
#media (max-width: 480px) {
.legend {
position: relative;
width: 100%;
}
.pie {
margin: 0;
}
}
.pie-legend ul {
list-style: none;
margin: 0;
padding: 0;
width: 300px;
}
.pie-legend span {
display: inline-block;
width: 14px;
height: 12px;
border-radius: 100%;
margin-right: 4px;
margin-bottom: -2px;
}
.pie-legend li {
margin-bottom: 4px;
display: inline-block;
margin-right: 4px;
}
As #B.ClayShannon mentioned, version 2 is quite a bit different than verison 1. Here is an example of how to customize the legend template using version 2.
options: {
legendCallback: function (chart) {
var text = [];
text.push('<ul class="' + chart.id + '-legend" style="list-style:none">');
for (var i = 0; i < chart.data.datasets[0].data.length; i++) {
text.push('<li><div style="width:10px;height:10px;display:inline-block;background:' + chart.data.datasets[0].backgroundColor[i] + '" /> ');
if (chart.data.labels[i]) {
text.push(chart.data.labels[i]);
}
text.push('</li>');
}
text.push('</ul>');
return text.join('');
},
legend: {display: false},
}
It's not shown directly in the accepted solution above, but to render your legend elsewhere you'll want to call:
$("#myChartLegend").html(myChart.generateLegend());
Finally, some HTML to pull it together (note clearfix is a Bootstrap class that :
<div class="chart">
<div style="float:left">
<canvas id="myChart" class="pie" style="max-width:300px;"></canvas>
</div>
<div class="legend" id="myChartLegend" style="float:left;"></div>
<div style="clear: both;"/>
</div>
This is what works (more or less) using version 2 of Chart.JS:
HTML
<h2 class="sectiontext">Top 10 Items</h2>
<br />
<div class="chart">
<canvas id="top10ItemsChart" class="pie"></canvas>
<div id="pie_legend"></div>
</div>

I say, "more or less" because the pie pieces are still pitifully puny:
I am facing something a little bit weird. Well, at least for my understanding.
Let me give you the snippet, so you can see what I am doing

app.controller('cuitCtrl',function ($scope, $window) {
$scope.defaultCuit = '--Inserte su CUIT aquí--';
$scope.riskData = {

});
app.filter('selectedPlan',function(){
return function(planSolicitado,planAnterior){

If you run it, you can see that an alert box defined in the function I've created for my button is getting activated without me having clicked it. I think this maybe has something to do with where I declare the ng-app and ng-controller, but failed to find something useful.
What am I missing here?
I'm assuming you're trying to call the reset() function, right? It seems you've called it right after declaring it on the controller.
$scope.reset = function () {
$scope.riskData.cuit = angular.copy($scope.defaultCuit);
$window.alert('Hey! You clicked!');
};
$scope.reset(); // <--- You're calling it here
$scope.comboData = {
Remove the $scope.reset(); line from your controller and you should be good to go :)
