<sup>function Clicked(XCoord, YCoord: Integer; Var SegmentIndex, PointIndex: Integer): Integer;

Type Library
TeeChartx

Description
Returns -1 if the XY pixel coordinates are *not* over any level segment lines.</sup>

^{Returns the level index (starting from zero) otherwise.}

^Example

^{'where Series(0) is a ContourSeries}

^{levelndex = TChart1.Series(0).Clicked(X, Y) ' Get the contour point index.}

^{If levelndex <> -1 Then}

^{myText = Format(TChart1.Series(0).asContour.Levels.Items(levelndex).UpToValue, "0.0")}
