Re: [Matplotlib-users] 3D Data to 2d Plots

Philip, A few questions before I give one possible solution, Does this plot need to be updated in real time ? or is this plot to be done in post processing? if you can do the plots with post processing you should be able to use pcolor function to do your tasks http://matplotlib.so

[Matplotlib-users] 3D Data to 2d Plots

Hi list, I want to visualize Plots over time. This describes the data: [image: 3dplot.png] a) and b) are single scans, the cutting at the red bars is no problem. c) illustrates how they are done over time. d) is what I want. I think this plot

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

[Matplotlib-users] pyplot: Extract contourset without plotting

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

Re: [Matplotlib-users] How to draw a specific country by basemap?

Hi, Adding some extra work in the readshapefile method in your code allows you to play with the region names etc,... I've just made a new tutorial script to show this : http://www.geophysique.be/2011/01/27/matplotlib-basemap-tutorial-07-shapefiles-unleached/ Thom

Re: [Matplotlib-users] How to draw a specific country by basemap?

Hi, that would do: data = m.readshapefile(r'borders\ita_adm1','itaborder',linewidth=0.5) italy = data[4] print dir(italy) italy.set_facecolors('red') italy.set_alpha(0.5) I think at some point you"ll meet the limitations of the method, you might need to use another shapefile-reading module
