TFunctionPeriodStyle

type TFunctionPeriodStyle = (psNumPoints, psRange);

Unit
TeEngine

Description
TFunctionPeriodStyle defines the possible values of the TTeeFunction.PeriodStyle property.

For example, TAverageTeeFunction and TMovingAverageFunction have a Period value. This is a numeric value that can be expressed either as a number of points or a horizontal range.

    • \*\pn
      \pnindent\pntxtb
    \fi-200\limsNumPoints     A number of points (for example: 20).
    • msRange     A X value range (DateTime or not).


    Example:

    AverageSeries1.PeriodStyle := psRange ;
    AverageSeries1.Period := DateTimeStep[ dtOneDay ] ;


    That will construct a Series based on its DataSource Series. For every group of points within a Day, it will calculate its average.
