Analysis: Mathematics: Simple Curve Math
Perform simple arithmetic on a curve or XY data range.
Input XY data range or curve
The operand type.
Specifies a curve (XY Range) as operand. This option is available when you select Reference Data from the Operand drop-down. When the two datasets' coordinates differ, the two curves will be interpolated or extrapolated with linear interpolation before the specified operation is performed.
Specifies a constant as operand. This option is available when select Const from Operand drop-down.
Specifies the formula to calculate, in which y1 means Input1 and y2 means Reference data. This option is available when Custom is selected from Operator drop-down list.
Operate on the common range between the two curves. This checkbox is available when select Reference Data from Operand drop-down.
Specify whether to rescale the source graph after arithmetic operation.
Specifies the output data range. In script, the default option is <input>, while in GUI, defult is <new>.

Minimum X value of output curve
Maximum X value of output curve
Mean X value of output curve
Minimum Y value of output curve
Maximum Y value of output curve
Mean Y value of output curve
The original curve will be subtracted. The result should show as follows:
