I am calling a PageMethod in codebehind.aspx.cs file which returns me a string array[] in the javascript code in the aspx page the problem at hand is that string array returns Time(X axis-Value),Data/Name(Y axis Value),Type(Defines the type of chart (Spline or Column)) from a WEB SERVICE. I am using that data to add series dynamically to the chart. Using the function chart.AddSeries() but I am unable to do so.
Can anyone please guide me how to do that and upon doing that I want to add points to the particular Series.
Please Note that I would be displaying to types{Spline and Column} on the same chart.
<script type="text/javascript">
alert("Bingo");
$(function () {
$(document).ready(function () {
Highcharts.setOptions({
global: {
useUTC: false
}
});
var chart;
chart = new Highcharts.Chart({
chart: {
renderTo: 'ltrChart',
type: 'spline',
marginRight: 10,
events: {
load: function () {
PageMethods.GetSingleValue(function (result) {
var Name = new Array();
var Type = new Array();
var Data = new Array();
var Time = new Array();
var Ser = chart.series;
for (var i = 0; i < 6; i++) {
Type[i] = result[i].split('-')[0];
Name[i] = result[i].split('-')[1];
Data[i] = result[i].split('-')[2];
Time[i] = result[i].split('-')[3];
chart.addSeries({ name :Name[i], data : [ [Time[i], Data[i]] ] }, true, true);
/* Test Method To ensure data Fetching */
// alert(Type[i] + Name[i] + Data[i] + Time[i]);
// alert(result[i]);
}
})
//console.log(typeof PageMethods.GetSingleValue);
// PageMethods.GetSingleValue();
setInterval("PageMethods.GetSingleValue()", 5000);
}
}
},
title: {
text: 'Live random data'
},
xAxis: {
//type: 'datetime',
//tickPixelInterval: 150
},
yAxis: {
title: {
text: 'Value'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
formatter: function () {
return '<b>' + this.series.name + '</b><br/>' +
Highcharts.dateFormat('%Y-%m-%d %H:%M:%S', this.x) + '<br/>' +
Highcharts.numberFormat(this.y, 2);
}
},
legend: {
enabled: false
},
exporting: {

},
series: [{
name: 'Test Data',
data: [[10, 50], [15, 55]]
}]
});
});
});
</script>
This is what I’ve done and works like a charm. On a side-note, since you mentioned aspx page, why don’t you just buy the dot net highcharts library? It makes life a lot easier if you’re a dot net fan!
I am initially creating a chart with 5 elements, and then using the “iterated” JSON serialized string to pass data to client-side. Traversing the elements gives me a dynamic live chart!
You can add as many series as you like; you can use a loop if needed and the same code I’ve added as a function can be used to create the chart completely in Javascript.
