^{ICurveFittingFunction.LastPoint
ICurveFittingFunction}

<sup>property LastPoint: Integer;

Type Library
TeeChartx

Description
Default Value: -1</sup>

^{Sets the last point index used to display the fitting}

^{With FirstCalcPoint and LastCalcPoint properties you can restrict the subset of points CurveFittingFunction will use to calculate the polynomy coefficients and it's point values.}

^{Example [Visual Basic]:}

^{In this example LastPoint is being used with FirstValueIndex / LastValueIndex to refit a fitted curve (CurveFitSeries1) to a 'zoomed' series (LineSeries1).}

^{Private Sub TChart1_OnZoom()}

^{With TChart1}

^{If .Series(0).FirstValueIndex > 0 Then}

^{.Series(1).FunctionType.asCurveFit.FirstCalcPoint = _}

^{.Series(0).FirstValueIndex - 1}

^{.Series(1).FunctionType.asCurveFit.LastCalcPoint = _}

^{.Series(0).LastValueIndex}

^Else

^{.Series(1).FunctionType.asCurveFit.FirstCalcPoint = _}

^{.Series(0).FirstValueIndex}

^{.Series(1).FunctionType.asCurveFit.LastCalcPoint = _}

^{.Series(0).LastValueIndex}

^{End If}

^{If .Series(0).LastValueIndex - .Series(0).FirstValueIndex > 6 Then}

^{.Series(1).FunctionType.asCurveFit.FirstPoint = _}

^{.Series(0).FirstValueIndex + 1}

^{.Series(1).FunctionType.asCurveFit.LastPoint = _}

^{.Series(0).LastValueIndex - 1}

^{End If}

^{.Series(0).CheckDataSource}
