IContourLevel.DefaultPen
IContourLevel

property DefaultPen: WordBool;

Type Library
TeeChartx

Description
Returns True when this level has no special custom pen.

By default all levels have no custom pen, that is, they use the Contour series pen property to draw all levels with the same pen.

As soon you change a level Pen property, this function returns False.

Series1.Levels(0).Pen.Color = vbRed

To use the default series pen, set pen to "nil" :

Series1.Levels(0).Pen = nil
