Hi again Paul,

OK, I am now at a workstation where I can test commands and send you
what I find works:


>I am plottong out the mosaic radar images but wouldnlike a background
>color of white instead of black...but i cant figure out how to do that.

Here is what I did:

- display a NEXRCOMP 1km national composite base reflectivity product:

IMGDISP NEXRCOMP/1KN0R-NAT LINELE=1500 2368 PLACE=C MAG=-5 -5 EU=BREF24 SU=X 
ALL=26 SF=YES REFRESH='EG GRA=(GRA);MAP FILE=OUTLUSAM MCOL=1 WID=1 
GRA=(GRA);BAR (GRA) SU=X X COL=7 ORIENT=VER;TE ?LASTFRM (GRA)'

- list out the display/colors used in the BREF24 enhancement:

  244 255   224 224   128 128   255 255
EU: Done

- change the black background to white:

EU MAKE 0 2 WHITE

All white (bright white) seems kind of glaring, so I toned it down to
a gray shade:

EU MAKE 0 2 GRAY

>Also, on the WWDISP i am trying only the watches...but there is a label
>that says warnings...anyway to get rid of that?

I tried:

WWDISP TYPE=SEVWATCH TORWATCH WINWATCH FLOODWATCH TIME=0 23:59:59

and now see the 'Warning' label that you want to get rid of.  It looks
to me that putting up the 'Warning' label when no warning is asked for
is a deficiency/bug in WWDISP.  The only thing I can offer you at this
point is a procedure on how to blank out the label using CW:

- find the location of the center of the label 'Warning' in TV coordinates
  (this will depend on the size of your frame).  For my 700x950 frame, 
  the center of 'Warning' is at 650x64.

- use CW to fill/erase the graphics under the cursor:

PC T 650 64
CW 0 X 15 100

You will probably have to play with the values for PC and CW a bit, but
once you find a set that works for your display, it can easily be
incorporated into scripts that produce displays.

Cheers,

Tom
