Re: [Matplotlib-users] depth longitude plot

[Sudheer J. <sud...@ya...>]

Hi Benamin,
I was looking for a plot similar to the attached one named ferret.gif. But from matplot lib I get flat fill and contours which are not aligned to the levels ( named figure_1.png , it looks like matplotlib has just flat surfaces as it used pcolor.

with best regards,
Sudheer

Thank you,
                       I just posted this question in numpy lists thinking that it is possible after regriding the data to new axes. 
Thanks for the help.
with best regards,
Sudheer

You can overlay contours on the pcolormesh image by simply using the plt.contour() function after the pcolormesh() call.  It allows you to control which levels to contour and you can specify the attributes of those contours like the color or thickness.  Note that unlike Matlab, you don't have to call "hold on" between plots.  By default, matplotlib will hold.

I hope that helps!
