Re: Multiple faults in pslegend

Hi Paul,

Thanks for taking care of this so quickly. I can confirm that the pslegend with multiple faults is working as expected in r13381.

Cheers,
Dave

>>> Anyway, we don’t know enough about GMT to determine what we need to do to resolve this error message, so we’re hoping perhaps one of you knows how we should modify our GMT script to plot multiple faults in the legend. I’ve attached a simple example script that should reproduce the multiple fault plotting issue. Must everything is commented out for now, except for an attempt to plot two faults.
