Folks,
Merry Christmas!
While I'm waiting for the family to show up to open
presents this morning, I've been doing a little work. :-)
One of the problems Coyote Graphics routines have had
with legacy IDL code is interpreting LONG integers
correctly as color table index numbers, rather than
as numbers that can be decomposed into three separate
colors.
I have solved this problem this morning by writing
a new Coyote Graphics program, cgDefaultColor, which
all the Coyote Graphics programs will take advantage
of to obtain their color values (usually as a string
that can be used with cgColor to get a color in a
device independent way).
The input to cgDefaultColor can be a scalar or an
array, and the data type can be undefined, byte,
int, long, or string. You can learn more about
it here:

It should solve a number of problems that people
have been having with AL_Legend.
You will need an updated Coyote Library:

Best Wishes for the New Year!
Cheers,
David
