Re: Working...

Ok,

	So this might not be a question for this list but here goes.  I have
used the set palette defined to (1 "red", 2 "white", 3 "blue") and that
shows the data greatly.  And I set cbrange to [-1:1].  Now all the -2
values are set to bright red, as they should be.  Is there a syntax
where I can say I want to interpolate the colors  between like -1 and 0
as red to white, between 0 and 1 interpolate between white and blue and
all colors from -1 and down go to black?  I am sure there is a way to do
this, without makeing a huge color xref file.  The help documentation
for the set palette is kinda confusing.  Thanks for the help.
