Re: Re: about color key and plot a rectangular
Hi, Jaison Kurian,
You did me a big favor. Thanks.
Why i couldn't find out it in the Ferret user guide.
Question 1: sp rm -f map.gif >>>>i wonder why
you add this command befor "frame/file=map.gif".
Question 2: pls see the attached jnl file. when i plot the upper view it is
ok, but when i plot the upper and lower view together there is a question. As if
the etopo5 data file closed after the first plot by itself, and when plot the
second figure it does not exist. It is so strange! Have you ever
encountered it?

Hi Gao Rongzhen,
I made few modifications to your script and is
working fine for me (on my pc, Fer5.8). Have a trial with the modified
script (please see the attachment color_key1.jnl).
You can get a box overlayed on your plot in many ways. Two methods are
illustrated in color_key1.jnl.
1. use box.jnl
usage : GO box xlo xhi ylo yhi [pen_number]
for details see this file /usr/local/fer5.8/go/box.jnl
this is the most easy method
2. use plot command
define the corner points and plot it using the qualifiers
/ov/vs/line
Please let me know if you need more explanation.
With Regards
Jaison

Pls look at the attached figure. My problem is why the color from -9000 to -10000 is gray not blue? Is there a way to solve it?
