ISeries.Delete
ISeries

procedure Delete(Index: Integer);

Type Library
TeeChartx

Description
The Delete method will remove the # ValueIndex point from the Series values lists. The Chart will be automatically redrawn. Dependent Series will be recalculated.

Example [Visual Basic]:

We want to delete the 8th point of a Line Series:

TChart.Series(1).Delete(7) (remember, points index start at zero)

This will remove completely the 8th point in the 1st Series. The Chart will be repainted and all dependent Series (whose DataSource is Series(1)) will be recalculated and redrawn.
