Re: [Matplotlib-users] pyplot: Extract contourset without plotting

Daniel, Following on from Eric's comments, attached is the simplest example I could come up with to do what you want. For non-filled contours, the 'segs' (last few lines of the file) should be fairly self-explanatory, and this is hopefully what you want. If you are after filled contours, you wil

Dear all, contourset = pyplot.contour(..) calculates the contourset but also grabs whatever figure is currently active *somewhere* in the entire code and whichever scope it was created. The contours are plotted into it. While I could possibly live with that, I would really like to suppress any
