Subtract Value, reached from the Waveform menu, removes an offset value for the signals in the active signal viewer. By clicking on Subtract Value, a pop-up window appears with the following option:
- "Mean Value" removes the mean of the signal.
- "Value" allows to specify the value to be subtracted.
Warning: the offset may be hidden by the offset correction in the Properties of the Graphic viewer (tab "Layers", box Values). On the contrary to this appearance option, "Subtract value" modifies the temporary signal.
Note: In Geopsy toolboxes, the mean is automatically removed for all signals and windows.
