Please accept my apologies for the confusion. If I've understood you right this time I can suggest the following:
- default behavior
for the RadDiagram
- panning behavior
- start panning with CTRL+ left mouse and dragging the current viewport for the both controls
To achieve this behavior we can set in the ChartPanAndZoomBehavior
property to None by default and only when the CTRL is pressed to set the DragMode
to Pan. For your convenience I implemented this approach in the attached project. Please take a look at it and let me know if it works for you.
