Default period for LowFunction is 0 (By default, LowFunction will show the lowest 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..

If more than 1 data series is added as datasource for LowFunction then the period default changes to 1.

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

LowFunction class Example

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(tfLow)

{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.
