Developing Drill Down Functionality on a Line Chart using RadHtmlChart

[Sampath]

Hi there,

I am using RadHtmlChart control to display the absenteeism of several production plants on a daily basis. To accomplish this I am using the line series and each plant has a line series <telerik:LineSeries> of its own.

I was able to do this part successfully. See Image 1. 

Now each production plant has many departments and each department has many designations. 

What I want to do is when I click on a particular plant (when I select a particular line) I should be able to get the department level details belonging to that particular plant I selected.

Same goes for the getting the designations of a selected department (within the plant I selected) when I drill down furthermore.

Have followed the example mentioned here : http://demos.telerik.com/aspnet-ajax/htmlchart/examples/drilldownchart/defaultcs.aspx

This is for a column chart and it doesn't show me how I can identify the selected trend line.

string seriesName = RadHtmlChart1.PlotArea.Series[0].Name; 

Instead of getting the name of the LineSeries at the 0th Index, I want the name of the selected LineSeries.

Please help.

Hi Sampath,

You can use the approach from the mentioned demo - get the series name for the seriesClicked argument:

args.get_seriesName()
