Hi,

I would like to know if it's possible to use the NZoomTool(not the NDataZoomTool) with a polar chart?

The goal is to have the ability to make a zoom on a part of the chart with a frame drawed by the mouse.

This frame has always a 1:1 ratio for width/height due to the polar chart nature.

How could I achieve this for one chart(my chartControls contains 3 charts, only one is a polar chart and needs this feature).

I found this:
http://support.nevron.com/KB/a185/implement-zooming-panning-axis-scrolling-nevron-chart-net.aspx
But:
1. This is a zoom on data, and I need a zoom on the whole plot(with axis that aren't always at the same position)
2. Doesn't seems to works with polar, I guess because of the RangeSelection that isn't available

Thank you very much

Hi Julien,

This feature is not present in the control, however it can be implemented only for value axes (it does not seem logical to implement it for angular axes). Can you describe further what the desired behavior will be in this case?

Hi,

I've a ChartControl, that has three charts.
Two are cartesian, one is polar.

I've to zoom only on the polar(the DataZoom on cartesian works already fine).


The goal is to draw a frame(like with the DataZoomTool, except it has a fixed width/height ratio, corresponding to the chart size). When we finish to draw(OnMouseUp), we zoom on this part.

I attached you two pictures with the normal.png(before zoom) and zoomed.png(when we have made the frame and zoomed on it).

Thank you for the support
