Scroll Prev Top Next More |
Calculates the Euclidean 'L-2' norm for the values in the SourceChart over the time period and adds the value to the TargetChart. The 'L-2' norm is the square root of the sum of squares. 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.

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) |
