Can't display axis to my rickshaw chart - json

I'm trying to display x- and y-axis to my charts.
I'm using JSON for the data.
This is my following code :
new Rickshaw.Graph.Ajax( {
element: document.getElementById("chart"),
width: 580,
height: 300,
renderer: 'line',
dataURL: 'dataoutevo.json',
onData: function(d) {
return d },
onComplete: function(transport) {
var graph = transport.graph;
var hoverDetail = new Rickshaw.Graph.HoverDetail( {
graph: graph
} );
var shelving = new Rickshaw.Graph.Behavior.Series.Toggle( {
graph: graph,
legend: legend
} );
},
series: [
{
name: 'ligne1',
color: '#c05020',
}, {
name: 'ligne2',
color: '#30c020',
}, {
name: 'ligne3',
color: '#6060c0'
}, {
name: 'ligne4',
color: 'red'
}
],
onComplete: function() {
var x_axis = new Rickshaw.Graph.Axis.Time({
graph: graph
});
x_axis.graph.update();
}
}
);
Can anyone help me and tell me how to do it ?
I have numbers as x- and y-datas (not words)

new Rickshaw.Graph.Ajax( {
element: document.getElementById("chart"),
width: 580,
height: 300,
renderer: 'line',
dataURL: 'dataoutevo.json',
onData: function(d) { d[0].data[0].y = 80; return d },
onComplete: function(transport) {
// important . do not forget
var graph = transport.graph;
var detail = new Rickshaw.Graph.HoverDetail({ graph: graph });
var legend = new Rickshaw.Graph.Legend({graph: graph,element: document.querySelector('#legend')});
var xAxis = new Rickshaw.Graph.Axis.Time({graph: graph});
xAxis.render();
var yAxis = new Rickshaw.Graph.Axis.Y({graph: graph});
yAxis.render();
var shelving = new Rickshaw.Graph.Behavior.Series.Toggle({
graph: graph,
legend: legend
});
var highlighter = new Rickshaw.Graph.Behavior.Series.Highlight({
graph: graph,
legend: legend
});
var order = new Rickshaw.Graph.Behavior.Series.Order({
graph: graph,
legend: legend
});
},
series: [
{
name: 'ligne1',
color: '#c05020',
}, {
name: 'ligne2',
color: '#30c020',
}, {
name: 'ligne3',
color: '#6060c0'
}, {
name: 'ligne4',
color: 'red'
}
],
});

Changing Rickshaw.Graph.Axis.Time to Rickshaw.Graph.Axis.X worked for me in a very similar situation. BTW your example code shows two definitions of onComplete, which I assume isn't intended?

Google Charts - Not Drawing - JSON Response

I would like to lead with google charts is brand new to me and I could be making a really dumb mistake. I have been working on this all day and no matter what I do, I can't get my google chart to draw using my json data. I think it has something to do with the columns and rows. I've made alot of changes different ways and I've given up at the below information. I'm not getting any errors but my chart isn't loading. I've looked at so many threads and examples now that nothing is making sense. Any help is appreciated!
<div class="col-lg-12">
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<div id="pieDisconnectReasonsChart" style="min-height:271px"></div>
</div>
<script>
google.charts.load("current", { packages: ["corechart"] });
google.charts.setOnLoadCallback(drawDisconnectReasonsChart);
function drawDisconnectReasonsChart() {
var jsonData = $.ajax({
url: "/Reports/RunDisconnectReasonsReport",
type: "POST",
dataType: "json",
data: {
openDate: #Html.Raw(Json.Encode(Model.OpenDate)),
closeDate: #Html.Raw(Json.Encode(Model.CloseDate)),
},
})
.done(function (jsonData) {
var data = new google.visualization.DataTable(jsonData);
data.addColumn("string", "SY_OPEN_LBL");
data.addColumn("string", "SY_DESCRIPTION");
data.addColumn("number", "TOTAL");
data.addColumn("number", "PERCTWODEC");
data.addColumn("number", "PERC");
data.addColumn("number", "ErrMsg");
Object.keys(jsonData).forEach(function (row) {
data.addRow([
row.SY_DESCRIPTION,
row.SY_OPEN_LBL,
row.TOTAL,
row.PERCTWODEC,
row.PERC,
row.ErrMsg
]);
});
var options = {
title: 'Disconnect Reasons',
titleTextStyle: { color: 'black', fontSize: 22, bold: true },
legend: {
position: 'bottom', textStyle: { fontSize: 8 }, alignment: 'center'
},
chartArea: {
width: '98%', height: '80%'
}
};
var chart = new google.visualization.PieChart(document.getElementById('pieDisconnectReasonsChart'));
debugger;
chart.draw(data, options);
});
};
</script>
the data format for a pie chart only allows for two data table columns.
one string and one number.
unless you're providing a custom tooltip, then a third string column is allowed.
next, you're manually adding columns and rows to the data table,
so you need to remove the jsonData variable from the constructor, here...
from...
var data = new google.visualization.DataTable(jsonData); // <-- remove jsonData
to...
var data = new google.visualization.DataTable();
if you want to create the data table directly from json,
the json must be in a specific format, found here...
Format of the Constructor's JavaScript Literal data Parameter
with the above method, you would not need to manually add columns and rows,
and the chart would be faster, depending on the amount of data anyway...
try removing the extra columns and correcting the constructor,
and it should work, similar to the following working snippet...
google.charts.load("current", { packages: ["corechart"] });
google.charts.setOnLoadCallback(drawDisconnectReasonsChart);
function drawDisconnectReasonsChart() {
var data = new google.visualization.DataTable();
data.addColumn("string", "SY_OPEN_LBL");
data.addColumn("number", "TOTAL");
data.addRow([
'CAT A',
2
]);
data.addRow([
'CAT B',
6
]);
var options = {
title: 'Disconnect Reasons',
titleTextStyle: { color: 'black', fontSize: 22, bold: true },
legend: {
position: 'bottom', textStyle: { fontSize: 8 }, alignment: 'center'
},
chartArea: {
width: '98%', height: '80%'
}
};
var chart = new google.visualization.PieChart(document.getElementById('pieDisconnectReasonsChart'));
chart.draw(data, options);
};
<script src="https://www.gstatic.com/charts/loader.js"></script>
<div id="pieDisconnectReasonsChart" style="min-height:271px"></div>
EDIT
in the done method,
it appears your looping on the keys of your json object.
Object.keys(jsonData).forEach(function (row) {
instead, loop on the json object itself.
jsonData.forEach(function (row) {
see following snippet...
google.charts.load("current", { packages: ["corechart"] });
google.charts.setOnLoadCallback(drawDisconnectReasonsChart);
function drawDisconnectReasonsChart() {
var jsonData = $.ajax({
url: "/Reports/RunDisconnectReasonsReport",
type: "POST",
dataType: "json",
data: {
openDate: #Html.Raw(Json.Encode(Model.OpenDate)),
closeDate: #Html.Raw(Json.Encode(Model.CloseDate)),
},
}).done(function (jsonData) {
var data = new google.visualization.DataTable();
data.addColumn("string", "SY_OPEN_LBL");
data.addColumn("number", "TOTAL");
jsonData.forEach(function (row) {
data.addRow([
row.SY_DESCRIPTION,
row.TOTAL
]);
});
var options = {
title: 'Disconnect Reasons',
titleTextStyle: { color: 'black', fontSize: 22, bold: true },
legend: {
position: 'bottom', textStyle: { fontSize: 8 }, alignment: 'center'
},
chartArea: {
width: '98%', height: '80%'
}
};
var chart = new google.visualization.PieChart(document.getElementById('pieDisconnectReasonsChart'));

Integrating maps in Cytoscape

I am currently using Cytoscape JS to visualize a network but I would like to overlay the graph on a world map and plot the nodes to specific locations. The Tokyo Railways Demo is similar to what I have imagined but the background is black. I want my map to look like the google maps and have similar zoom in and out capabilities. It would be great if there is a way to integrate the google maps in the Cytoscape graph.
Cytoscape.js on Google Maps, a demo code based on a sample overlay-simple. The current state is rough, but it works.
Try running the code below in full screen. To zoom IN/OUT, use press_Ctrl + scroll_wheel.
The best platform to test this code is jsfiddle.net, by forking the original code and replacing parts with the code presented here.
/*
Status: google_APIkey is good for development only

// This example creates a custom overlay called CyOverlay, containing
// a U.S. Geological Survey (USGS) image of the relevant area on the map.
// Set the custom overlay object's prototype to a new instance
// of OverlayView. In effect, this will subclass the overlay class therefore
// it's simpler to load the API synchronously, using
// google.maps.event.addDomListener().
// Note that we set the prototype to an instance, rather than the
// parent class itself, because we do not wish to modify the parent class.

How to get Piwik Json Data and use it with chart.js?

I use the piwik php api to generate data like this:
[
{"label":"1680x1050","nb_visits":9,"nb_actions":53,"max_actions":27,"sum_visit_length":3051,"bounce_count":3,"nb_visits_converted":0,"sum_daily_nb_uniq_visitors":7,"sum_daily_nb_users":0,"segment":"resolution==1680x1050"},
{"label":"1440x900","nb_visits":1,"nb_actions":1,"max_actions":1,"sum_visit_length":0,"bounce_count":1,"nb_visits_converted":0,"sum_daily_nb_uniq_visitors":1,"sum_daily_nb_users":0,"segment":"resolution==1440x900"}
]
and i want to use chart.js to visualize this data, at the moment my code looks like this and doesn't work:
var chartjsData = [];
var chartjsLabel = [];
$.getJSON("piwik.php", function (json) {
///src = http://stackoverflow.com/questions/24696329/how-to-use-json-data-in-chart-js
for (var i = 0; i < json.length; i++) {
chartjsData.push(json[i].nb_visits);
chartjsLabel.push(json[i].label);
}
});
var barChartData = {
labels :[chartjsLabel],datasets : [
{
fillColor : "rgba(220,280,220,0.5)",
strokeColor : "rgba(220,220,220,1)",
data : chartjsData
}
]
};
var ctx = document.getElementById("myChart").getContext("2d");
var myChart = new Chart(ctx, {
type: 'bar',
data: barChartData,
});
can maybe someone give me a working example how to work with chart.js and piwik's json data, or a hint how to get this working, thanks alot!
I got it like this:
var label = [];
var data = [];
$.getJSON("piwik.php", function (json) {
for (var i = 0; i < json.length; i++) {
label.push(json[i].label);
data.push(json[i].nb_visits);
}
graph();
});
function graph(){
var ctx = document.getElementById("myChart");
var myChart = new Chart(ctx, {
type: 'bar',
data: {
labels: label,
datasets: [{
label: '',
data: data,
backgroundColor: [
'rgba(255, 99, 132, 0.2)',
],
borderColor: [
'rgba(255,99,132,1)',
],

},

How can i draw simple line in column chart in google-charts API?

I have a simple column chart. using the google-charts API:
JS code:
function drawChart() {
var data = google.visualization.arrayToDataTable(<?php echo $str ?>);
var options = {
title: 'Business Optimization Per Predicted Conversion Rate',
bar: {groupWidth: "70%"},
colors: ['purple','grey'],
fontSize:20,
legend: { position: "none" },
width: 900,
backgroundColor: { fill: '#efeff0'},
};
var chart = new google.charts.Bar(document.getElementById('chart_div_1'));
chart.draw(data, google.charts.Bar.convertOptions(options));
My question is: How can i draw simple line here?
Horizontly to the X-axis.

Select which columns from CSV to graph with HighChart

What am I doing wrong? Thank you in advance:

if(lineNo !== 0) {
var x = + new Date(items[1]+'/'+items[2]+'/'+items[0]+' '+items[4]),
kwh = parseFloat(items[5]),

if(!isNaN(kwh) && !isNaN(savings)){
options.series[0].data.push([x,kwh]);
options.series[1].data.push([x,savings])
}
}
});
});
new Highcharts.Chart(options);
});
Here is the jsfiddle:http://jsfiddle.net/tonystinge/3bQne/1223/
I got it now...
// data is variable from $.get()
$.get('http://www.geoinc.org/Dropbox/geo/sites/GC_ROOM/EXAMPLE.csv', function(data){
// parsing here...
});
new Highcharts.Chart(options);
});
Your problem is the placement of the new Highcharts.Chart(options) call. $.get (like most ajax calls) is asynchronous So the new Highcharts will be called before it completes.
Change it to this:
// data is variable from $.get()
$.get('http://www.geoinc.org/Dropbox/geo/sites/GC_ROOM/EXAMPLE.csv', function(data){
var lines = data.split('\n');
$.each(lines, function (lineNo, line) {
var items = line.split(',');
if(lineNo !== 0) {
var x = + new Date(items[1]+'/'+items[2]+'/'+items[0]+' '+items[4]),
kwh = parseFloat(items[5]),
savings = parseFloat(items[6]);
if(!isNaN(kwh) && !isNaN(savings)){
options.series[0].data.push([x,kwh]);
options.series[1].data.push([x,savings])
}
}
});
new Highcharts.Chart(options); // this is now in the $.get callback function
});
