[Matplotlib-users] Setting a user defined color for each marker of a Line2D
Hello, I am trying to plot a line assigning a user specified color to each marker. The idea is that if I have n points x, n ppoints y, I was expecting to be able to provide n markeredgecolors or n markerfacecolors as a (npoints, 4) array of RGBA values. However that does not seem to be possible (or I have failed to find it). The closest thing to that functionality I have found is based on creating a colormap with as many entries as points to be plotted: http://stackoverflow.com/questions/16834861/create-own-colormap-using-matplotlib-and-plot-color-scale and that only seems to work with scatter plots. Any hint about how to generate a Line2D object with a user specified set of colors (therefore not needing to create and use a colormap)?

Re: [Matplotlib-users] Can not display 3D plot !
Resending to the list, but also with amendments to my previous statement (the new gmail app is really crappy with viewing conversations...) Ah, I see I missed that in the original message (I was heading out the door at the time). You say there is a crash. Is there a traceback or segfault? Also, was there a previous installation of matplotlib on the system? If so, which version? Amendment: I see the original email noted that ipython would sometimes report errors and sometimes would not. Could you try running those scripts in a regular python environment? I have seen situations where ipython would completely swallow or misreport oddball import issues. My suspicion is that there is a version 1.2 installation of mpl_toolkits that is getting mixed up with the version 1.3 or 1.4 installation of matplotlib. We have seen odd issues like this back when the devs were going back and forth between v1.2 and v1.3 when we change the installation system.

Re: [Matplotlib-users] Setting a user defined color for each marker of a Line2D
If you want each marker to be a different color you have to use scatter. You can pass scatter a sequence of colors (see http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.scatter) so you don't have to go through making a custom colormap.

Re: [Matplotlib-users] Control of the display of the navigation toolbar --- how?
Also note that there is an rcparams context manager ( http://matplotlib.org/api/matplotlib_configuration_api.html#matplotlib.rc_context) that will take care of the boiler plate of temporarily changing an rcparam.

Re: [Matplotlib-users] Can not display 3D plot !
Someone installed Vizard on my PC before, which has its own python distribution, that may be the reason of all those troubles. I uninstalled it. Then I tried the code with python without any IDE from the Windows console. The same kind of thing happens. With agg backend, no error, but no figure either. With the default backend, I just get a window with python.exe has stopped working or something like that. Python does not provide any error, but I found the windows report, I attached it to the mail.

Re: [Matplotlib-users] Can not display 3D plot !
No OpenGL. The 3d graphics all goes through the same layering engine as the 2D plots. They aren't real 3D plots but rather what I like to call 2.1D plots. A single point of a 3D element is chosen to determine how to layer it with everything else. So, it is very easy to get visualization artifacts, especially with polygons. Do this from python: import matplotlib import mpl_toolkits.mplot3d print matplotlib.__file__ print mpl_toolkits.mplot3d.__file__ And tell us what that returns. Cheers!

Re: [Matplotlib-users] Can not display 3D plot !
Yeah, I am at a real loss here. Can you try one of the axes_grid1 examples? Also, how about the basemap examples? Those are both mpl_toolkit packages as well and might behave similarly. Also, it would be interesting to figure out at exactly which step the failure happens. There is a package called faulthandler that is really useful for that: http://faulthandler.readthedocs.org/en/latest/ It is a bit limited on Windows, but it is better than nothing. Also, does it fail regardless if you are doing savefig() or show()? Unfortunately, the traceback info you provided doesn't seem to be encoded properly (or at least, not auto-detectable).

The 3d graphics all goes through the same layering engine as the 2D plots. They aren't real 3D plots but rather what I like to call 2.1D plots. A single point of a 3D element is chosen to determine how to layer it with everything else. So, it is very easy to get visualization artifacts, especially with polygons. Do this from python: import matplotlib import mpl_toolkits.mplot3d print matplotlib.__file__ print mpl_toolkits.mplot3d.__file__ And tell us what that returns. Cheers!
