I have been creating column charts using the google chart tool, but am struggling to add a Y axis to my charts. I just need a standard series of values to appear on the axis on the left hand side of the chart.
I am able to create and manipulate the X axis but the Y axis will not appear for some reason. I'm sure there is something simple I am missing here.
Also apologies if the following code is messy, I am pretty new to this.

Thanks in Advance,
the y-axis is being hidden by chart option --> chartArea: {width: "100%"}
chartArea controls the size of the center section where the bars are,
and does not include the labels on either axis or at the top
use height & width outside of chartArea for the entire chart
if you want to maximize the chart area, then set limits on left, bottom, top, and / or right,
recommend replacing with the following...
height: '100%',
width: '100%',
chartArea: {
top: 32,
left: 32,
bottom: 32,
right: 12,
height: '100%',
width: '100%'
}
see following working snippet...
google.charts.load('current', {
packages: ['corechart']

var data = google.visualization.arrayToDataTable([

I have a simple application that shows some charts. I want the user to be able to move the charts around on the screen. I have utilized the drag and drop API to try and achieve this, and it is working for the text that is included in the div container, but unfortunately, when it drops, I lose the chart and its information.
I have tried playing around utilising different meme types but I have been unsuccessful. Perhaps the drag and drop API cannot achieve this?
var ctx = document.getElementById("barChart1");
var barChart = new Chart(ctx, {
type: 'bar',
data: {
labels: ["Dog", "Cat", "Pangolin"],
datasets: [{
backgroundColor: '#00ff00',
label: '# of Votes 2016',
data: [12, 19, 3]
}]
}
});
var ctx = document.getElementById("barChart2");
var barChart = new Chart(ctx, {
type: 'bar',
data: {
labels: ["Dog", "Cat", "Pangolin"],
datasets: [{
backgroundColor: '#ddd',
label: '# of Votes 2016',
data: [12, 19, 3]
}]
}
});
document.addEventListener('DOMContentLoaded', (event) => {
var dragSrcEl = null;
function handleDragStart(e) {
this.style.opacity = '0.4';
dragSrcEl = this;
e.dataTransfer.effectAllowed = 'move';
e.dataTransfer.setData('text/html', this.innerHTML);
}
function handleDragOver(e) {
if (e.preventDefault) {
e.preventDefault();
}
e.dataTransfer.dropEffect = 'move';
return false;
}
function handleDragEnter(e) {
this.classList.add('over');
}
function handleDragLeave(e) {
this.classList.remove('over');
}
function handleDrop(e) {
if (e.stopPropagation) {
e.stopPropagation(); // stops the browser from redirecting.
}
if (dragSrcEl != this) {
dragSrcEl.innerHTML = this.innerHTML;
this.innerHTML = e.dataTransfer.getData('text/html');
}
return false;
}
function handleDragEnd(e) {
this.style.opacity = '1';
items.forEach(function(item) {
item.classList.remove('over');

How can we add tinymce editor in the place of editor present in the cell of ag-grid?
In order to customize ag-grid's cell's you need to create a custom Cell Renderer component.
You can pretty much put anything you want in that custom component, including tinyMCE.
More info: https://www.ag-grid.com/javascript-grid-cell-rendering-components/
Please see Cell Renderer

i have a angular web application with a line graph (using echarts) with multiple series.
the labels of the series are overlapping, is there a way to adjust their position or size etc to prevent them from over lapping ?
my code:
thisInstance._paidUnpaidSplitGraphOptions = {
title: {
text: 'Paid/Unpaid Claims'
},
tooltip: {
trigger: 'axis',
axisPointer: {
type: 'cross',
label: {
backgroundColor: '#6a7985'
}
}
},
legend: {
data: ['Unpaid Claims', 'Paid Claims']
},
grid: {
left: '5%',
right: '6%',
bottom: '5%',
containLabel: true
},
toolbox: {
feature: {
saveAsImage: {
title: "Download Image of Chart"
},
dataZoom: {
yAxisIndex: false,
title: { "zoom": "Zoom Chart", "back": "Remove Zoom" }
},
brush: {
type: ['lineX', 'clear'],
title: {
"lineX": "LineX", "clear": "Clear" }
}
}
},
xAxis: [
{
type: 'category',
boundaryGap: false,
data: xAxisData
}
],
yAxis: [
{
type: 'value'
}
],
series: [
{
name: 'Paid Claims',
type: 'line',
stack: 'WWWWWWWW',
label: {
position: 'TopLeft',
normal: {
show: true,
formatter: function (data) {
return thisInstance.GetFormattedValue(data);
},
color: '#151515'
}
},
areaStyle: { normal: {} },
data: paidAmounts
},
{
name: 'Unpaid Claims',
type: 'line',
stack: 'WWWWWWWW',
label: {
normal: {
show: true,
formatter: function (data) {
return thisInstance.GetFormattedValue(data);
},
position: 'BottomRight',
color: '#151515'
}
},
areaStyle: { normal: {} },
data: unPaidAmounts
}
]
}
html code:
<div class="clr-row">
<div class="clr-col-2">
</div>
<div class="clr-col-8">
<div echarts [options]="this._appService.GraphsService._paidUnpaidSplitGraphOptions" class="demo-chart"></div>
</div>
<div class="clr-col-2">
<button class="btn btn-outline btn-sm" (click)="this._appService.ClaimCaptureService.GetHpCodesLagReport()"><clr-icon shape="download"></clr-icon>LAG REPORT</button><br />
<button class="btn btn-success-outline btn-sm" (click)="this._appService.ClaimCaptureService.GetHpCodesAgeReport()"><clr-icon shape="download"></clr-icon>AGE ANALYSIS REPORT</button>
</div>
</div>
What i have tried so far is to change the position of the labels as you can see in the above code t making the one 'TopLeft' and the other 'BottomRight', but this didn't seem to help at all the labels are still overlapping.
below is a screenshot of what it looks like
To move text slightly you can use offset: [0,-15], reference.
However you might want to use the label formatter to mask the labels that are under a certain value.
Example
var data = [
[820, 932, 901, 934, 1290, 330, 320],
[0, 0, 0, 0, 0, 900, 1320]
];
var option = {
xAxis: {
type: "category",
data: ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"]
},
yAxis: {},
itemStyle: {
},
series: [{
data: data[0],
type: "line",
stack: "stack",
color: 'blue',
areaStyle: {
color: 'blue',
opacity: 0.3
},
label: {
position: "top",
offset: [0, -15],
show: true,
}
},
{
data: data[1],
type: "line",
stack: "stack",
areaStyle: {
color: 'red',
opacity: 0.3
},
label: {
position: "top",
show: true,
formatter: function (params) {
return (params.value === 0) ? "" : params.value;
}
}
}
]
}
var dom = document.getElementById("container");
var myChart = echarts.init(dom);
if (option && typeof option === "object")
myChart.setOption(option, true);

You should try avoidLabelOverlap = true
I find that the google documents are i bit limited in explaining if this is possible
how would you strip out all the empty space in a google candlestick chart.
Then fit the candlestick over a background element
code

</style>
</head>
<body>

use the chartArea option to stretch the chart to the edges of the container
chartArea: {
backgroundColor: 'transparent',
top: 0,
left: 0,
bottom: 0,
right: 0,
height: '100%',
width: '100%',
},
set the background and various other colors to 'transparent',
then you can apply any background to the <div> element

I am using Highcharts to plot the graph of temperature vs time. I am having a JSON file wherein data from the backend keep updates the JSON file. I want to call ajax function such that the graphs automatically generates with respect to time. How to do that? I am new to high charts, please help me.
You can use Series.addPoint method.
http://api.highcharts.com/highcharts/Series.addPoint
Here is a example of using Highcharts with live data with GET HTTP requests.
const options = {
chart: {
type: 'spline'
},

},
xAxis: {

},
yAxis: {
title: {
text: 'Price (USD)'
}
},
legend: {
enabled: false
},
exporting: {
enabled: false
},
series: [{
name: 'Live Bitcoint Price [USD]',
data: []
}]
}
const chart = Highcharts.chart('container', options)
// Data
const getData = () => {
setInterval(() => {
window.fetch('https://api.cryptonator.com/api/ticker/btc-usd').then((response) => {
return response.json()
}).then((data) => {
chart.series[0].addPoint({ x: data.timestamp * 1000, y: Number(data.ticker.price) })
})
}, 3000)
}
getData()
