Has there been any work on touch support for the Chart control? I found this old post that mentioned support being worked on in 2012 Q2.

The features we want to implement are:

  • Swipe to pan
  • Pinch to zoom
  • Tap to place custom markers
  • Drag to move custom markers

I could not find anything in the API documentation, could you give me any pointers as to how to implement this?

Hello Wouter,

The RadChart control is the older control from the both charting controls our Telerik UI for WPF suite offers. It is in maintenance mode from quite some time and this is why I would like to recommend you using the newer charting control - RadChartView. It has touch support and you can find more information about its gestures and control's behavior using this link.

Hope this helps.

Thank, that's the one we're actually using. I always mix up the names and the Rad in front of it in some places doesn't make it any more clear. Also the actual name of (one of the charts), RadCartesianChart, has no relation to the official name ChartView.

Hi Wouter,

Thank you for your feedback on this. Actually the ChartView is the suite for three separate controls - RadCartesianChart, RadPieChart and RadPolarChart, each of them visualizing data in a different coordinate system - cartesian, radial or polar. Having this in mind we decided to go with the RadChartView on top several years ago.
