Hello
I have a need where I need to plot a multi line live chart , in which number of lines will be decided dynamically. Each line corresponds to a entity .
As a feature , User going to select the number of entities , those entities data will be gathered from back end and the data should be plotted in line chart.
This data should get updated after 20 secs.
Can any one give some pointer on this, how can I achieve this dynamic multi line chart?

You can check these samples:

http://www.jqchart.com/samples/RealTime/LiveData
http://www.jqchart.com/samples/RealTime/ChartSeries
http://www.jqchart.com/samples/RealTime/ChartDataPoints

After you get the new data from your backend, you can create the chart series and update the jqChart. The code can be something like:

Code:

var series = [];

for (var i = 0; i < yourBackEndData.length; i++) {
   series.push({ type: 'line', data: yourBackEndData[i].data });
}

$('#jqChart').jqChart('option', 'series', series);
