LabelModeAngular


Unit:SDL_polchart
Class:TPolChart
Declaration: property LabelModeAngular: TpcAngLabelMode;

The property LabelModeAngular determines how the angular scale will be labeled:

almNone no labels at all
almDegrees display degree values in the range of 0 to 360
almRadians display radians in the range of 0 to 2p
almMultiPi display angle in integer multiples of some fraction of p (in the range of 0 to 2p)
almSymmDeg display degree values in the range of -180 to +180
almSymmRad display radians in the range of -p to +p
almSymmMultiPi display the angle in integer multiples of some fraction of p (in the range of -p to +p)

Please note that the labeling does not automatically correspond to the kind of used units. You can for example use the polar diagram with radians (set UseDegrees to FALSE) while displaying degrees (LabelModeAngular := almDegrees). Further the kind of labelling does not affect the polar coordinate system (e.g. -50 degrees is equal to +310 degrees).

Example: This property is used in the following example program (see http://www.lohninger.com/examples.html for downloading the code): poldiag
