First of all: thanks for the new version, there are many new and appreciated features :-)

While playing with the demo app, I found this odd behaviour with the ViewPolar. If you use the mouse wheel to zoom out, the amplitude axis can get separated from the rest of the diagram:

Hi Andreas and thanks for the report.

The zooming out can indeed break the polar chart drawing.
For now this can be prevented by using BeforeZooming event, that has a Cancel property that cancels the ongoing zooming.

Unfortunately there is a bug in the event that causes the reported new zooming scale to be always 1. This'll be fixed in the next release.
