Description
TWindRoseSeries is a Polar Series displaying Wind directions,
TWindRoseSeries is a small component which derives from Polar Series.
It overrides the default labels around the polar circle perimeter to show "Wind" directions ( North, South, West, East, etc ).
It is provided as an example of Series customization.
The "AngleIncrement" property controls how many labels around the circle will be displayed.
By default WindRose is configured to plot labels every 30 degree.
Series1.AngleIncrement := 30;
"Wind" data can be added using the AddPolar method:
MyAngle := 180 ; { wind coming from the south }
MyValue := 123 , { wind speed value }
Series1.AddPolar( MyAngle, MyValue, '', clRed );
