Interface IPolarPropertySet

public interface IPolarPropertySet

This interface is used to modify the properties associated with a 2D polar chart.

A handle to an object that implements this interface can be obtained by calling the gethPolarProperties method defined in QbChart.

eg. QbChart chart = new QbChart(...);
IPolarPropertySet polar = chart.gethPolarProperties();
