Re: [ferret_users] vector representation

["William S. Kessler" <william.s.kessler@xxxxxxxx>]

Hi Marco -

First, for postscript/pdf output, it is usually better to thicken the  
vectors (or any lines) in the plot commands:

vector/line=7 ucomp,vcomp    ! or /line=13

This method may look terrible on the screen, but will print much better.

Second, there have been a few scripts contributed to the user group  
that thicken lines in post-processing and discuss this question.  
Search the user group archives for "thicken".
