Select Range

Hi,

I would like to be able to select an area on a chart. This could be similar to the selection used by NDataZoomTool, except with a custom event handler

Ideally the area could then be dragged or, by dragging the border, resized

Any thoughts?
Many thanks,
Neil

Hi Neil,

This generally requires a custom tool (similar to the NDataZoom tool), but with altered Drag / End Drag behavior. We'll add this feature in the Vol2 release of the control as currently the implementation of such tool cannot be achieved trough the public API (some important overrides in the base NDragTool are obfuscated). Alternatively it can be achieved using transformations / hit testingg, but this will be cumbersome. We’ll try to add this functionality in the control as non documented in the SP coming next week and keep you posted.

Sorry to post to such an old thread but here we are 4 years later and I can find no clue of such a tool... was one ever developed to meet this need?  If so, can you point me to where it can be located?

Hi Bill,

You can check the custom drag tool example - Interactivity \ Tools \ Custom Drag Tool. Hope it helps - let us know if you meet any problems or have any questions.
