Re: [Matplotlib-users] Missing \Delta in mathtext

Re: [Matplotlib-users] Missing \Delta in mathtext
I see what's going on here. Upper-case Greek letters are always upright (non-italic) in mathtext. TeX does this, and it is apparently a long standing American typographic convention. So, when it goes to print the \Delta, it looks at mathtext.rm, which in your case you have set to serif, which causes it to look at the setting for font.serif, in which the first font it finds is Bitstream Vera Serif, which doesn't have Greek characters. Personally, I like to set the math fonts explicitly, rather than using the font categories. This is what I set for using Arev Sans: mathtext.cal : Arev Sans:oblique mathtext.it : Arev Sans:oblique mathtext.rm : Arev Sans mathtext.bf : Arev Sans:bold mathtext.sf : Arev Sans I may consider adding arev and arevsans values to mathtext.fontset that would do nothing more than set the mathtext.* values to reasonable defaults to avoid this confusion. (Which would of course require that the Arev fonts are available -- they aren't included with matplotlib). I still think it's useful and reasonable to provide access to full font customization, but it would be nice to support the common case in a more direct way. Hope that helps.

[Matplotlib-users] Matplotlib very slow
Hi, I have compiled v.0.90.1 on RHEL 5. By default, the GTKAgg backend is being used (TkAgg cannot be set, as TkInter is not installed on the system, I think. It throws a NO Module named Tkinter error). At any rate, a test session is as follows: import pylab pylab.plot ( [1,2,3],[1,2,3],'-or') #Wait for a long time, up to 3-4 minutes pylab.show() # Display the graph. Quite fast 1sec This delay is very unusual, and does not happen on my laptop. Does anyone have any ideas? Thanks!

All the stuff we are defining in matplotlib/__init__.py, like rcParams and friends, is being lost. Instead, a import matplotlib dir(matplotlib) just shows the special names '__path__', '__doc__', and '__name__', and the 'toolkit' dir.

I'm relatively new to matplotlib and what I'll ask to you seems to be simple

In matlab I use axis('ij') but in matplotlib I couldn't find something

I am not 100% sure what you are asking and I don't have a matlab
install handy to test. If you want to plot a decreasing scale on the
y-axis, that is easy, just invert the min and max args to the ylim
ax.set_ylim(ymax, ymin)
If you want to do something more sophisticated, please describe in
detail and then I may have to tell you it is not currently supported

[Matplotlib-users] Contours on imshow with limited range
Hi, I limit the value range of my imshow using vmin and vmax. As I like the way the contour levels are usually coloured by contour, I would like to just restrict them to the same range but have matplotlib use the default spacing and colouring. In other words, I want to avoid setting levels manually. Is that possible at all? There is obviously no vmin and vmax in contour but can I do this is some other way? Or do I have to set up my own array for the levels to achieve this? Cheers, Christian - SF.Net email is sponsored by: The Future of Linux Business White Paper from Novell.
