Hi,

I'm plotting a matrix with the contourf function. As this matrix represents
a signal spectrum there are many distinct peaks. When viewed as a 2D filled
contour plot some of the contour lines are so close together near the
spectral peaks as to appear like black bands across the plot. Is there any
way I can turn the black contour lines off and leave just the coloured
contour regions?

Thanks in advance,

Pete

Try the command

shading flat

Just in case you didn't catch this when you posted the identical
query to comp.soft-sys.matlab (which would have been the correct
place to put it):

I'm not sure this is the quickest way, but contourf will return handles
to the contours:

[mumble, H, grumble] = contourf(thingo);

for q=1:length(H)
set(H(q),'LineStyle','none')
end
