Is there a way to suppress the contour lines and filling, leaving only stippling? I have been experimenting with it but no luck. I have a contourf of a 2D variable and a separate 2D array indicating regions of statistical significance (i.e. a mask, which equals 1 in cells where the variable is significant and equals 0 else), and I want to put black hatching over the contourf where it is significant. I can get this to work, but still with a black contour line surrounding the hatched region. I'd like to remove the line, leaving just the hatching. Thanks!

Re: [Matplotlib-users] cross hatching in contours?
As of matplotlib v1.2.0 you can hatch a contour set directly. There is an example in the gallery: http://matplotlib.org/examples/pylab_examples/contourf_hatching.html Hope that helps, Phil On 5 December 2012 17:28, spencerahill spencerah...@gmail.com wrote: Jae-Joon Lee wrote On Thu, Sep 15, 2011 at 10:33 PM, Jonathan Slavin lt; jslavin@.harvard gt; wrote: I'm wondering if there is some way to do cross hatching as a way to fill contours rather than colors (using contourf).
