background color

[sh zhou]

Dear All，

When I draw a station plot, the background color is always red, can you tell
me how to change it?
The following steps is what I did,
1.  I write two binary files for station data and background grid data
respectively.

In grid data file, I set all arguments value  zero,  and then the background
color is red when display , in this step how to change the background color?

2. I insert station data into  background grid data use command :" oacres",
but the background color is still red.

Does it means arguments in background grid data should be set with other
values? not "0"? or I should modify some parameters in step 2?

Another question is  how to extract station data from grid data( grid data
is model output), I'm so confused with the command "gr2stn",
would you like to do me a favor to tell me the specify steps about  how to
use it?

Thank you .

With regards.
