Description
\ltrparTWindRoseSeries is a Series displaying Wind directions, 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 "link TCustomPolarSeries.AngleIncrement#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 AddXY method:
MyAngle := 180 ; { wind coming from the south }
MyValue := 123 , { wind speed value }
Series1..AddXY( MyAngle, MyValue, '', clRed );
//multiple values..
Series1.AddXY( 30, 100, '', clTeeColor );
Series1.AddXY( 60, 200, '', clTeeColor );
Series1.AddXY( 90, 50, '', clTeeColor );
Series1.AddXY( 120, 150, '', clTeeColor );
