I use chartjs.org in my HTML template with variables

 

<script>

 

var cType="bar";

 

var xValues=["Item1","Item2","Item3"];

 

var yValues=[34,12,45];

 

....

 

</script>

 

I will with IWButton click change this variables and draw chart?

 

I tried with WebApplication.CallBackResponse.AddJavaScriptToExecuteAsCDATA('var cType = "line";'); and not work!

 

Maybe is any variant this implementation with RegisterCallBack for change my variables?

Try update your chart.

 

Code:

 

WebApplication.CallBackResponse.AddJavaScriptToExecuteAsCDATA('var cType = "line"; yourchart.update();');
