    i use with html5 websocket to receive, data , expect to show how many number of data received by counting length of array after split with ;
    and then show dynamic number of graph

    <!DOCTYPE HTML>

		text: "Gi0/4 Management port packet per seconds Chart"

		dataPoints: dataPoints2

updateData2();

var chart3 = new CanvasJS.Chart("chartContainer2", {

    Martin,

    Can you please explain the issue you are facing? It would also be useful if you can create a jsFiddle demonstrating the issue with minimal code.

    If you are just looking for an example using jQuery, here is one.
