Help, Log scale for Contour Plots ?

[G. Collins]

Is this what you want to do?
contour(peaks)
set(gca,'xscale','log')
Drew

Did you happen to notice that the isolines and the fill colors scale differently after applying the log scale to the x-axis? The isolines and fill colors don't match up in the log axes. I don't understand why this happens. Any thoughts?

Seems to me to be working fine in release R2015b. Can you post an example
where the colors are different after switching to log scale? Can you also
post the release you're using -- are you using one from before the new
graphics system was released in release R2014b?

Thanks Steve. I'm running 2015b. I posted a screenshot here:

I am not able to post the data set I am using, and unfortunately I could not re-create the problem using data from the peaks function or dummy data.

(BTW, is it possible to attach an image directly to a MATLAB Newsgroup post? I could not find a link to do this :-\ )

I see one plot here; since the X axis is in log scale, I assume this is the
"after" picture. Where's the "before" picture?

No, it is not possible.

Everything looks fine when both scales are linear.
