New Revision: 27138

URL: http://svn.gna.org/viewcvs/relax?rev=27138&view=rev
Log:
Fixes and improvements for the gnuplot correlation_matrix() plotting API 
function.

This is for the structure.atomic_fluctuations user function.  The "pm3d map" 
plot type is incorrect
for such data type, so instead of using 'splot', 'plot' is being used 
instead.  The resultant EPS
file is now much smaller.  The colour map has also been changed to one of the 
inbuilt ones for
higher contrast.
