Help with pswiggle -G syntax

Hello all,

I am having an issue with pswiggle when trying to fill the positive and negative sections of a wiggle with two different colors and I am getting an incorrect syntax error. Does anyone know the correct way to do this? On the pswiggle webpage, it looks like you would just do “-Gred+p -Gblue+n” if you wanted positive red spikes and negative blue ones but I can’t seem to get it and I have not been able to find any examples.


You did not actually show us en error so difficult to know what you got. Minimal test examples of all modules are in test/pswiggle I think (installation dependent). Please consider posting the information our gurus actually need to help:

GMT version and OS
Actual command
Error or output from command
Ideally a small example file so we can recreate the error

Without that we go in circles
