Description
Sets the Period to apply to a range (eg. DateTime month) or a number of Series Points.</sup>

^{Example [Visual Basic]:}

^{TChart1.Series(2).FunctionType.PeriodStyle = psRange}

^{TChart1.Series(2).FunctionType.Period = TChart1.GetDateTimeStep(dtOneMonth)}

^------------

^{'The range can also be used for non-datetime series:}

^{TChart1.Series(2).SetFunction (tfAverage)}

^{TChart1.Series(2).FunctionType.PeriodStyle = psRange}

^{TChart1.Series(2).FunctionType.Period = 100}

^{TChart1.Series(2).DataSource = "Series1"}

^{'This will calculate an average for each group of points}

^{'inside every "100" interval.}

^{'(Points with X >=0, X<100 will be used to calculate the}

^{'first average, points with X >=100, X<200 will be used}

^{'to calculate the second average and so on... )}

^{'Notice this is different than calculating an average for}

^{'every 100 points.}
