Re: [ferret_users] Contour Labels on White Box?



Thanks for the example - I thought that might be the kind of thing Jammal had in mind. Ferret does not have a label style of that kind.

 I believe what Jammal meant is like the attached graph which is not
generated by ferret but using  gri ( , though I am not sure if it is
possible in ferret. It is a good feature if implemented particularly
when the labels get embedded in background colors

I didn't understand the question (and still I'm not sure I understand it
even after Ansley's answer).

One solution to many of these dilemmas is to draw whatever you want using an
otherwise unused color, then do a simple edit of the resulting postscript
file to modify that particular color. Search the mail archives for "edit
postscript" and you should find instructions to change the colors by
modifying the "ct" (color table) code near the top of the postscript file.
It's pretty easy even if you know nothing about postscript code.

Another technique is to define two identical plot boxes (DEFINE VIEWPORT).
Make your background SHADE or FILL plot, then use the second viewport to
draw your white contours on top of that.

Hi Jammal,
No, there is not a way to make the labels for contour lines on a small
white background.  One idea for you to try is to use white for the lines and
labels, which might show up better, depending on the palettes you are using.

  yes? fill/i=1:15/j=1:15 i+j
  yes? contour/over/lev/color=white/i=1:15/j=1:15 i+j

Another thing people sometimes do is to make the final plot for a
publication, and then use a separate graphics editing program to make a few
changes to enhance the figure.  This might be another way to get exactly
what you want.

Dear Ferret users,

Is there any way to plot contour labels on white Box in CONTOUR command
not to be disturbed by FILLed or SHADed background?

Many thaks to you in advance.
