Description
HighFunction may be added to your project by Chart Editor at design time or at runtime using code. Default period for HighFunction is 0 (By default, HighFunction will show the highest point of all the series points). Period is applicable to the number of axis points, Period 1 = 1 axis point; period 2 = 2 axis points, etc..</sup>

^{If more than 1 data series is added as datasource for HighFunction then the period default changes to 1.}

^{HighFunction will work with any number of input series as datasource. The Datasource is best defined using the Chart Editor.}

^{HighFunction class Example}

^{To set the period for HighFunction you should use the FunctionType property of Series}

^{To define a function series by code you should first create a new series for the function. The series may be of any type.}

^{Visual Basic}

^{{ Set the function using the SetFunction method}.}

^{TChart1.Series(0).SetFunction tfHigh}

^{{You may then define the period for the function - here setting it to to 5}}

^{TChart1.Series(0).FunctionType.Period = 5}

^{To undefine (delete) a function defined for the series either delete or inactivate the Function Series or redefine the Datasource.}
