Hi Jimmy,

if you are happy with linear scale for the x and y axis,
any of the numerous program to plot images with axes will
do, but if it matters to you to have log scales as in the
Ulysses plots, I suggest to use

http://hea-www.cfa.harvard.edu/~pgrigis/idl_stuff/pg_plotima ge.pro

Example of usage:

pg_plotimage,dist(512,512),findgen(512),findgen(512)/10+1,/y log,/
xstyle,/ystyle

Ciao,
Paolo
