Re: [Matplotlib-users] question about building from source on windows
I was using version 3673 of svn (matplotlib) when it worked. I had a clean build directory (I usually kill it before trying to build a new version, along with whatever is in lib/site-packages). I'm not sure of the exact version I was using when it was dying (I want to say somewhere around 3660-69, but I tried a lot last week without success).

[Matplotlib-users] 3D scatterplot histogram + error ellipses
Hi all, I'm trying to display the histograms of lists of 2D vectors together with their error ellipses in a 3D plot. Plotting the histograms as 3D scatterplots is easy using matplotlib.axes3d.Axes3D( ).scatter3D( x, y, h ), but how do I draw the error ellipse in the ( x, y ) plane. I know how to create a matplotlib.patches.Ellipse object, but I'm pretty clueless on how to integrate it into the figure. Any help? -- Alex Borghgraef - This SF.net email is sponsored by: Splunk Inc.

[Matplotlib-users] Custom contour labels?
Hi, I am trying to make a contour plot using custom labels that consist only of text strings but can not figure it out. For example, if I do the following: A=arange(100) A=A.reshape(10,10) CS=contour(A,[50,]) clabel(CS) I get one contour line as expected, but instead of printing the contour level (50) I would like to print a simple string like Some String. I tried using the fmt option of clabel, but it requires a way to stuff in the level value (ie. fmt=Some String %f). Is it possible to use a simple string for these labels?

I don't know if there is a recommended way, but here is a quick hack:
class FormatFaker(object):
def __init__(self, str): self.str = str
def __mod__(self, stuff): return self.str
A=arange(100).reshape(10,10)
CS=contour(A,[50,])

[Matplotlib-users] How to use different fonts in mathtext

Re: [Matplotlib-users] How to use different fonts in mathtext
I believe the rcParams you're referring to actually affect the (now deprecated) mathtext2, which explains why they're having no effect ;) Sorry about that. These will soon be replaced with a new way to handle custom Unicode fonts, that is mostly working, but may not produce the best results. When typesetting math, symbols are pulled in from a number of fonts, and it looks best when all symbols are designed to match. For example, the freefonts don't have a very complete math symbol set at all. Falling back on the Computer Modern fonts for just those symbols would work, but won't look very nice. That said, a lot of users can probably do without those extended symbols altogether. The other nice thing that the Computer Modern fonts have is multiple sizes of many of the delimiters. For instance, as the '[' gets taller, it doesn't get wider as well. In any case, once I have an interface available for fonts to be replaced by the end user, I'll let you know and you can decide for yourself. I think I'm probably judging that option harshly based on the complete set of features available, not on a common subset that matters most.

You say that CM fonts/symbols look bad mixed with other fonts -- that
is also my experience from years of LaTeXing...
However, I often just want to put powers on units -- e.g., m^3 s^
{-1}, and serifed fonts look terrible as superscripts for sans fonts.
Perhaps there is another way to get what I want?
Also, the main problem I find when mixing CM symbols (e.g., \epsilon)
with other fonts is that the CM fonts seem small. Perhaps there is a
way to jack up the symbol size to that it matches the non-CM fonts in
a more reasonable way?

Angus McMorland a écrit :
Since all sorts of data can be displayed in am mpl window (e.g. a

scalar value to display. You could do this with the
motion_notify_event. Register it during init, something like:
self.canvas.mpl_connect('motion_notify_event', self.mouse_move_callback)
then in mouse_move_callback:
def mouse_move_callback(self, evt):
xpos, ypos = evt.xdata, evt.ydata
val = self.data[numpy.floor(xpos), numpy.floor(ypos)]
status_str = x: %4.2f y: %4.2f I:%4.2f \
% (xpos, ypos, val)
self.SetStatusText(status_str)
where data is your image variable. This works in a wx.Frame object,
which has a SetStatusString method for displaying the values. I'm sure
you could find an equivalent in your traits app.
Thanks, I'll look at this asap (as I got other stuff on fire).
BTW, I can't ever get (in fact, I don't know how) working
the coords to be displayed in my traits app.
I guess this is more related to traits, not to mpl.
For what it's worth, mpl embedded in wx also _requires_ the use of
motion_notify_event to get co-ordinates to display. It doesn't happen
by default except in stand-alone mpl as far as I can tell.
But the mpl embedded in traits app guru is on holydays for now.
Let's wait...

Re: [Matplotlib-users] How to use different fonts in mathtext
There is now experimental support for custom fonts in math mode.
You'll need to set mathtext.use_cm to False, and then set up a mapping
from each of the TeX font names to the name of your desired font.
It is assumed that the fonts are Unicode fonts -- it will use the same
font for both Latin and Greek characters. If your font doesn't have
Greek characters, it will (optionally) fall back on the Computer Modern
fonts. There isn't (at present) a way to fall back to a Greek-only
font. (There would, IMHO, have to be a compelling reason to add that
functionality, since there are too many font options to test already ;)
Here's an excerpt from matplotlib.template:
# The following settings allow you to select the fonts in math mode.
# They map from a TeX font name to a 3-tuple of the form:
#(family, weight, style)
# These settings are only used if mathtext.use_cm is False, otherwise, the
# Bakoma TeX Computer Modern fonts are used.
#mathtext.cal : (['cursive'], 'normal', 'normal')
#mathtext.rm : (['serif'], 'normal', 'normal')
#mathtext.tt : (['monospace'], 'normal', 'normal')
#mathtext.it : (['serif'], 'normal', 'oblique')
#mathtext.bf : (['serif'], 'bold', 'normal')
#mathtext.sf : (['sans-serif'], 'normal', 'normal')
#mathtext.use_cm : True
#mathtext.fallback_to_cm : True # When True, use symbols from the
Computer Modern
# fonts when a symbol can not be found in one
of
# the user-specified math fonts.

Agreed.
Perhaps there is another way to get what I want?
Try the above, and let me know how it goes...
Also, the main problem I find when mixing CM symbols (e.g., \epsilon)
with other fonts is that the CM fonts seem small. Perhaps there is a
way to jack up the symbol size to that it matches the non-CM fonts in a
more reasonable way?
If the Unicode font has both Latin and Greek characters in it, those
characters should play well together. More generally, though, I agree,
and one might run into that problem using some of the more obscure math
operators. Perhaps scaling one or the other font to get the x-heights
to match might work. I'll have to look into that further...
Thanks for spurring me on to get this custom font stuff together.
Cheers,
Mike
