Re: [ferret_users] Odd lines on postscript with fill command

[Stephen Guimond <sguimond@xxxxxxx>]

Hi Roman, Billy and others,

Thank you for those suggestions.

First, I tried what Billy suggested (shade first then overlay with fill) this give me a better plot, but the lines are still there (now the right color, but obvious odd lines).

Next, I tried Roman's suggestion and indeed unchecking the aliasing box in ggv does remove the lines.  However, I am sending these files to a journal office and they will probably still print out with those lines since the file itself was not changed, just the viewer.

Note that I tried converting from plt to ps with Fprint and the same line feature is there.

Any other suggestions?  

Steve
