Dear Telerik team, 

I have requirement to display detail data when click on selection data in chart. Is it possible using telerik chart ?

For Example :

I have pie chart that shows Gender percentage, Male 40%, Female 60 %. I want to display detail when click on Male.

If possible, please give me example how to do it.

 

Thanks in advance

 

Hi, Richard,

In order to achieve the desired outcome, you can take advantage of the ChartSelectionBehavior. Eventually, you can use the SelectionChanged event to show additional data for the data point which has been selected. For example, you can show a popup page designed according to your needs and expose additional properties of the business object within it. I have attached a sample project that shows such approach. I am using the Telerik DataForm to show some additional properties. Also, the Rg.Plugins.Popup is used.

Please have a look at the attached sample and consider a similar approach at your end. Of course, you are not limited to using the same setup, you can show any element of your choice based on the selection of the chart.

Have a great week.

Thanks In Advance

 

Hi Divya,

I noticed there is a separate thread on this topic and I would ask you to continue the communication there:
