Polar Trouble

Post by walker1 » Wed Mar 02, 2005 10:01 am

Hi

1. Which tools work on polar charts.
2. Trying to use an series function seems to result in a straight curve and not a"circular" one.
3. Is it possible to have a logarithmic grid. At least when you choose logarithmic axis.

Best Regards

Ole

Hi Ole,

1) The majority of the Tools has not been designed to be used with this Series type. I've not checked one by one, but you should to be able to use only the ones that not require a special ValueList, point order, etc.. like Drag Marks tool, Marks Tip tool, etc..
2) Yes, the functions has not been designed to be used in this series type (Polar)
3) Logarithmic axis for all circled series is not yet supported. At the moment the only way around this is to manually calculate Log(radius) and draw polar rings directly onto Chart.Canvas by using TCustomPolarSeries.DrawRing method.
