Hi all,
I don't understand how to include colours in a contourf plot. Is it possible ?
You need to change the colormap. BTW, it seems that imagemagick is used
for contourf output, so your result will be a matrix graphic.
Another thing is: is there a way to do as Matlab i.e. precise the axes for
contourf. For example doing something like contourf(xaxis, yaxis, matrix)
You can use "contour" this way, whose output is gnuplot.
A last point is that sometimes when I use contourf I get some errors like:
error: expecting integer index, found 2.291667
error: evaluating argument list element number 1
error: called from `contourf' in file
`/usr/share/octave/2.1.71/site/m/octave-forge/plot/contourf.m'
then I juste type the same contourf command and everything works.
I get this same behavior. I encourage to try Octaviz
(octaviz.sourceforge.net). There exists a contour function in Octaviz
which gives nice output. A "contourf" function (filled contour) doesn't
exist yet, but if you get Octaviz installed and express interest, I can
make one.

Jonathan
