confirmed by looking at
http://www.adobe.com/type/browser/info/charsets.html
Adobe western 2 has the same info.
Alt-0179 or U+00B0
So, best is to use the degree sign.
If you're not sure, what's present at rendering time, maybe try to force the generator to convert fonts to ps paths. 
But i donÄt know if matplotlib has tat optin at all...

Okay, fair enough.
But do you have any ideas, how to force the PS creator to use a different
font?
Say -> font Times-Bold

Hi,
Le 27/02/2013 10:01, Sudheer Joseph a écrit :
> I was checking the plt.xcorr and it calls the np.correlate in side it.

Just as a side note, mode=2 is the old fashioned way to specify
mode='full' [1]. This may help in reading the numpy.correlate doc.
This being said, I'm really unfamiliar with cross-correlations. I just
kind of know the usual 95% confidence interval for autocorrelation at
1.96/sqrt(n). Just as a quick check, this is what R uses by default, but
there are options like ci.type get more appropriate intervals for an MA
series
(http://stat.ethz.ch/R-manual/R-patched/library/stats/html/plot.acf.html)

Hi,
I need to set the frame off for my plots, so that I can have axes only on the sides I want, rather than on all four sides.
I do it this way:
from pylab import *
fig = figure(figsize=(3,2),dpi=300,facecolor='w')
ax = fig.add_subplot(111,frameon=False)
ax.add_artist(Line2D((0, 0), (0, 1),color='k',linewidth=0.5))
ax.add_artist(Line2D((1, 1), (0, 1),color='k',linewidth=0.5))
ax.set_yticks([0,1])
ax.set_xticks([0,1])
show()
Unfortunately, now the ticks and axes-lines are misaligned, as seen in the screenshots attached. In the second screenshot, I've panned the plot, so the misalignment is even more visible.
matplotlib.__version__ gives '1.1.1rc'
matplotlib.get_backend() gives 'TkAgg'
-------
If I use 'WX' backend by adding these two line before the above code (before pylab import):
import matplotlib
matplotlib.use('WX')
then the misalignment still appears to be there, but that is because the Line2Ds are clipped in their width, but the ticks are not. This is seen by panning the plot.
I can set the clipping of the Line2Ds off by doing:
l1 = ax.add_artist(Line2D((0, 0), (0, 1),color='k',linewidth=0.5))
l1.set_clip_on(False)
l2 = ax.add_artist(Line2D((1, 1), (0, 1),color='k',linewidth=0.5))
l2.set_clip_on(False)
So, WX backend is fine.
Backend 'GTK' doesn't even have the above clipping problem.
-------
But any workarounds for the TkAgg backend? Because my production machine doesn't have either wx or pygtk installed, so I can only use TkAgg.
Thanks,
Aditya.

That did it, Ben!
Many thanks,
Chad

Most likely, you need to clear out matplotlib's font cache. How to do that for windows, I don't know, but for Linux, it is as simple as "rm ~/.matplotlib/fontList.cache". Maybe there is a similar file somewhere on your system. After getting rid of that file, at the next import of matplotlib, it will recognize that that file is gone and rebuild it.
Cheers!

Just out of curiosity, I looked at the list of ASCII printable
characters
(http://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters) and
didn't find the degree sign. However, I found it in the so-called "8
bits extensions", which I believe is just the same as the Unicode U+00B0
character.

Hi, All,
I am using matplotlib 1.2.0 under Windows 7 64-bit.
I am trying to get matplotlib to recognize a new font that I downloaded (Arimo, for the curious). I put the .ttf files in the matplotlib ttf font directory (...\\fonts\\ttf\\ArimoRegularLatin.ttf, etc.), where Bitstream Vera Sans, STIX, etc. live. But matplotlib does not recognize the new font, and defaults to Vera Sans. If I load the font_manager and do a findfont, it does not find the new font and defualts to Vera Sans.
I also tried putting the ttf files in the system font location, with the same results. When I do this, other programs like Word can see and use the font.
Is there some trick that I'm missing, here?
Thanks,
Chad

Hello,
Does matplotlib recognize the file generated by a file sink in GNU Radio? I
guess its format is '.dat'.
I want to read the information in this file and create some graphics.
Thanks!

Ok, I finally got it working after a couple of hours of experimenting. I
couldn't figure out how to get your methods to work, maybe because I'm such
a novice at Python. But, it was as easy as using a simple 'for' loop.
num = the number of lists to plot
time = a list of lists
volts = a list of lists
figure()
for x in range(0,num):
 plot(time[x],volt[x])
show()

Sudheer:
It sounds like your needs are beyond the scope of matplotlib. It'll
probably be more productive to check in with the numpy or scipy mailing
lists.

Marcello: As a workaround you could mask the data outside the bounding 
lat of the projection before you draw the contour lines. Something like 
this ought to do it:
from numpy import ma
sst = ma.masked_array(sst, mask=lats>-40)

Marcello: I asked what version of basemap you had, not matplotlib. 
Anyway, thanks for providing the script - with it I can reproduce the 
problem. It looks like the Text instances returned by clabel are not 
being clipped properly. Unfortunately, I don't have any idea why. I'll 
get back to you if I find a solution.
BTW: you don't need to shift the lons and lats to represent the center 
of the gridbox (that's only needed for pcolor).

I'd say it's got nearly nothing to do with matplotlib.
The question is: will the font be included in the .ps and in the .pdf?
If not, which is most likely, it's upon the renderer to decide what to do if the requested glyph in the requested font is present or not in the system.
pdf is more likely to have the fonts / glyphs used also embeded in the pdf. One reason for them to be bigger than .ps. Ps, on the other hand, most of the times relys on the renderer to have the exact same font, referenced by name, pre-loaded in the system. Go figure.
To sum it up: use the old 7-bit equivalent for the degree sign, not any fancydancy UTF-8 character that is commonly not included in ye olde style postscript standard font embedded into your laser printer waaaay back then in the last millenium...

That feature is specific to the Qt4 backend.

Can anyone explain to me why I don't see the "Edit Curves Line and Axes
Parameters" button in the matplotlib toolbar when using
matplotlib.backends.backend_wxagg.NavigationToolbar2Wx
The example code here creates a Matplotlib plot with the matplotlib toolbar
including all buttons except for the one above.

Marcello: I cannot reproduce your problem. From the github pull request 
you mention, it seems like this was fixed about 3 months ago. What 
version of basemap are you running?

A few years ago, Gökhan Sever posted this technique, which is the simplest
and best I've seen:
##
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.cm as cm
x = np.linspace(0, 3 * np.pi, 5000)
y = np.sin(x)
z = np.cos(0.5 * (x[:-1] + x[1:])) # 1st derivative
cmap_z = cm.coolwarm(z)
fig, ax1 = plt.subplots(nrows=1, ncols=1)
ax1.scatter(x, y, c=cmap_z, marker='_', s=5)
fig.show()
##

Hi
have a look at http://matplotlib.org/examples/pylab_examples/multicolored_line.html and
http://matplotlib.org/examples/pylab_examples/show_colormaps.html.

Joe Kington's answer is the best solution I've seen to this problem:
http://stackoverflow.com/questions/13622909/matplotlib-how-to-colorize-a-large-number-of-line-segments-as-independent-gradi
There is also an example in the gallery:

Hi,
I am currently plotting cpu utilization over time (plot_time). I would like
the color of my line to be red when at 100%. 80-90% a bit less red, more
yellow, and lower numbers will be green. Any thoughts of doing this?

Dear Pierre,
            I was checking the plt.xcorr and it calls the np.correlate in side it. It calls np.correlate(ts1,ts2, mode=2).
Is there a way to see which vector is sided back in time? ie ts1[t1,t2,t3,t4....] ts2[t1,t2,t3,t4...] ( ts2[t2] correlated with ts1[t1] or ts2[t1] is correlated with ts2[t2] ie {to make out which one is the cause and which is effect)
in case of cross correlation it can be obtained by either sliding ts1 back in time or ts2 back in time. Is there a way to know this? I am not able to make much from np.correlate. Also is there a way to get 95% significance or p value from the xcorr.? in case of matlab? in matlab xcorr can be called with option of corcoeff instead of default cross correlation but is there similar option for matplotlib?
sincerely.

I am interested in using basemap and gdal to plot a georeferenced image, draw features on top of it, and then resave to the same georeferenced format. 
I'm wondering the easiest way to go about this. I made a first attempt (script & file attached), but am getting mixed up with all the coordinates (figure,image,georeferenced).
Thanks for any advice,
Scott

My matplotlib is a git clone of a couple weeks old.
There is this line in the PS file (opening via vim)
%%BeginResource: font KDYSTE+NewCenturySchlbk-Roman
don't know where it gets this.
#font.serif : DejaVu Serif, Bitstream Vera Serif, New Century
Schoolbook, Century Schoolbook L, Utopia, ITC Bookman, Bookman, Nimbus
Roman No9 L, Times New Roman, Times, Palatino, Charter, serif
font.sans-serif : DejaVu Sans, Bitstream Vera Sans, Lucida Grande,
Verdana, Geneva, Lucid, Arial, Helvetica, Avant Garde, sans-serif
PS uses that even I choose to use fot.sans-serif.
Dont see any font specification in the PDF file.
