Hi Joern,

You can't switch from one tool to another while the first one is still active. You can do so only if this is implemented as a single tool. In general the event handling mechanism in the chart is as follows:

1. The control dispatches the mouse event to all tools in the collection (in the order they appear there). If a tool wants to become active (for example a drag tool like the range selection) it cancels the event and then becomes the active tool. 
2. After a tool is activated all other tools do not receive mouse events
3. When the tool deactivates the whole process starts again from 1. 

We hope this helps - let us know if you have any questions or meet any problems with the implementation.

Hi Experts, I have a Chart where I want to have a zoom tool - but which allows the user after some zooming to activate range selection (via extra button) -> then select a range using NRangeSelectionMoveResizeTool -> then save the selected range values -> switch back to zoom mode

I have implemented a zoom tool and the NRangeSelectionMoveResizeTool:

So how can I switch between zoom and NRangeSelectionMoveResizeTool ?

Thanks for your help,
best regards,
Joern
