Calculates the greatest common divisor (gcd) of the SourceChart Values and adds the GCD to the TargetChart. The SourceChart Values are rounded into integers and the GCD calculated from this array. The GCD of two or more integers, when at least one of them is not zero, is the largest positive integer that divides the numbers without a remainder. For example, the GCD of 8 and 12 is 4.
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 GCD from
TargetChart
Type: TRSCustomChart
Chart to add the calculated GCD to
IndexLow
Type: Integer
Lower bounds index into the SourceChart
IndexHigh
Type: Integer
Upper bounds index into the SourceChart
TimeStamp
Type: TDateTime
TimeStamp to attach to the new value
SourceDim
Type: Integer
TargetDim
Type: Integer
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) |
