I have used RadHtmlchart with navigation and plotted the couple of line chart on it. Data set for all the line chart is coming from the server side. Is there way to get all the data set of all the line chart covered under  navigation using the javascript (Client side) so that I can manipulate it put some extra info like Min and Max etc based on the navigation selection area.

Hello Binary,

You can obtain the current data source through the get_dataSourceJSON() method. After that you can modify it and bind it back to the chart through the set_dataSource() method. You can read more information on this regards here - http://docs.telerik.com/devtools/aspnet-ajax/controls/htmlchart/client-side-programming/overview

Is there way to get the plotted point value only instead of the data source attached to radhtmlchart because I have seen the scenario where data source values are group by radhtmlchart and plotted the points instead of straight plotting the data source value. If I am not wrong in this case plotted point values and data source supplied is not same.

Hello Binary,

To get the plotted data for a particular series you can use the code below:

$find('ChartClientID').get_kendoWidget()._plotArea.series[0].data;
