[Matplotlib-users] setting user defined color map as default
Hi, I just created a hsv-like color map with gray levels only, now I'd like to use this as default color map. But how? Calling it like hsv() does not work and I did not find a hint in the documentation how to set a user defined color map interactively as default color map.

[Matplotlib-users] I really can't get into hist() barstacked
Hi all, I'd like to do a histogram with barstacked style. Well, I'm not able to make it in any way :( - what is the format of the the data to pass? - what's the value of bins? (related to the above question, I suppose) for example, let's say I want to plot this series s1 = 2,3,6,3,1 s2 = 1,2,2,4,1 s3 = 4,1,0,3,7 what's the format of data to pass to hist() ? by row? by column?

Re: [Matplotlib-users] speeding-up griddata()
Robert C, Robert K, folks, messing with the nice delaunay/testfuncs.py to time linear_interpolate_grid nn_interpolate_grid and nn_interpolate_unstructured in _delaunay, I see linear ~ 100 times faster than the nn_ s: # from: trigrid Ntri=1000 Ngrid=100 run: 21 Jul 2009 17:33 mac 10.4.11 ppc time: 0.027 sec trigrid: build Triangulation 1000 time: 0.0059 sec trigrid 100 linear corners: 0 1 2 1 time: 0.5 sec trigrid 100 nn_grid corners: 0 1 2 1 time: 0.49 sec trigrid 100 nn_unstruct corners: 0 1 2 1 Correct me: if all 3 methods do gridpoint-to-triangle in the same way, then the huge diff is in find-neighboring-triangles (6 on average ?), not in gridpoint-to-triangle ? This is with the _delaunay.so that comes with the mac 98.5.3 egg, however that was compiled (-O3 ?) What to do ? 1) does it matter, how many people care ? (all who believe in telekinesis, raise my right hand) 2) natgrid ? don't see it in matplotlib.sf.net 3) stick with fast linear, smooth the triangle planes a la 3t^2 - 2t^3 or fancier smoothing In any case, add griddata( ... method = linear / nn ... ) so users have a choice. Can a real user or two tell us about the flow, with some rough numbers for Ntri Ngrid Npix -- Ntri = nr original sample points, say 1000 Ngrid 100 x 100 Npix 800 x 600 ? (Ntri - Ngrid slowly and accurately, then Ngrid - Npix w fast inaccurate image interpolation ? hmm.) cheers -- denis -- View this message in context: http://www.nabble.com/speeding-up-griddata%28%29-tp24467055p24591133.html Sent from the matplotlib - users mailing list archive at Nabble.com. -- ___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
Re: [Matplotlib-users] Strange issue when using Matplotlib with PyQt4

The same happens ;) In your original post, you said: the widget in the Tab is incorrectly sized. If I embed the FigureCanvas in a QTabWidget the widget is to big, but if I put it in a QWidget it is shown correctly. Could you be more specific? What does incorrectly sized mean? What do you mean by the widget is too big, as opposed to shown correctly? Is this really a PyQt issue, or is it specific to matplotlib? If the latter we should continue the discussion on the mpl mailing list instead of cross-posting.

[Matplotlib-users] adjusting the height of rectangle legend handles
I know that there is a keyword argument for adjusting the width of legend handles but how would I reduce the *height* of rectangle label handles? -Chuck -- ___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
Re: [Matplotlib-users] adjusting the height of rectangle legend handles
The height of the box will scale with the font size. If you want to change the height independent of the font size, you need to manually adjust the properties of the individual legend handles. l = legend() patches = l.get_patches() # list of legend handles whose type is matplotlib.Patch. for p in patches: p.set_height(20) # height in point. you can also adjust y positionwith set_y method. Note that y=0 is the baseline.

Hello, Yes, the problem was really related to my version of matplot: i used matplot 0.98.5.2-4.fc11 before. I tried it with the latest svn revision (r7279) and it worked.
