Calculates the sample standard deviation (the square root of the sample variance) of all SourceChart's values over the time period and adds the value to the TargetChart. If the TargetChart is of a type that has more than 2 dimensions, such as a TRSLineChart with X and Y values, the new TargetChart value includes the TimeStamp.

Parameters
SourceChart
Type: TRSCustomChart
Chart to calculate the maximum from
TargetChart
Type: TRSCustomChart

IndexLow
Type: Integer
Lower bounds index into the SourceChart
IndexHigh
Type: Integer
Upper bounds index into the SourceChart
TimeStamp
Type: TDateTime

Note that this function is a class procedure so it may be called even if the TRSCustomChartFunction is not instantiated. The function can also be called by custom functions. For example, you could create a custom function that calls this function and then does something with the result (which is in the last value of the TargetChart) |
