Re: [ferret_users] Flipping colorbar

[mick spillane <mick.spillane@xxxxxxxx>]

Hi Savin,
   You could use "shade/set" followed by the  "PPL SHAKEY" command as 
in the following demo:

! the regular way
set view upper ; shade/i=1:10/j=1:10 i+j
! invert the color bar
set view lower ;shade/i=1:10/j=1:10/set i+j
ppl shakey,,,,,,,,,`($PPL$YLEN)+($PPL$YORG)`,($PPL$YORG)
ppl shade

To learn more about SHAKEY see the manual.  The symbols for plot 
dimensions used can be seen (after creating a plot) with PPL LISTSYM.  
SHAKEY needs the y-values in inches of the desired bottom and top of the 
color bar and the above simply flips the defaults.  If you wanted other 
values, or wanted to flip a horizontal color bar you could modify the 
SHAKEY parameters. Note that in PPL syntax the string of commas 
',,,,,,,' says to use the default value.

There are probably other ways to do the flipping too.
Good luck,
   Mick
