How to draw Null Points on the Polar?

Hello,

The polar series is not working properly when null are added.

SeriesLeftBoard.Clear ;
SeriesLeftBoard.AddPolar(45,140);
SeriesLeftBoard.AddPolar(55,145);
SeriesLeftBoard.AddPolar(75,114);

SeriesLeftBoard.AddNullXY(75,0);
SeriesLeftBoard.AddNullXY(100,0);

SeriesLeftBoard.AddPolar(101,170);
SeriesLeftBoard.AddPolar(192,123);

There should be a break between 75 and 100 degree. I expected to see a break in the plot like those in a fastline serie but i don't.

Thanks.

Hi Lixin,

This method is not functional for polar series since it derives from TCustomPolarSeries, a class which radar series also derive from. Radar series is not such an easy case to implement this functionality. We will try to include this feature for v8 which is the version we are currently working in.

Hi Lixin,

I'm afraid there's nothing that can be done for now. If you are interested we will send you the information to download TeeChart Pro v8 Beta. We have just implemented this feature there and a new beta, including this feature, will be posted very soon.

Hi Lixin,

I've just sent you the details to beta-test TeeChart Pro v8 VCL. The current version available still doesn't include this feature. We expect to post a new version very soon implementing this. We will also send you an example of the feature's usage.
