matplotlib-users Mailing List for matplotlib

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.

Good idea !

* your PDF file looks fine with Okular
* your PS indeed has the problem you describe (again Okular) :
  - "°" (degree sign) is fine
  - but "⁰" (zero superscript) is replaced by "?"

In case it may explain the difference : I'm using mpl 1.1.1rc2 from
Debian testing
and I have the following line in my matplotlibrc (is it relevant ???)

font.sans-serif     : DejaVu Sans, sans-serif

I believe you are looking for Proxy Artists:

You are right, U+00B0 is the right one. I think, I couldn't find a
"superscript o" easily then decided to use superscript zero from
http://en.wikipedia.org/wiki/Unicode_subscripts_and_superscripts

However, there is a slight difference in their appearance when I compare
them side by side.

For simplicity, I just use subscript and superscript unicode symbols to
construct simple units.

Could you test my outputs if they look fine on your side?

I just noticed that you are using here the character U+2070 "superscript
zero" (^(0)) while Ryan's proposition is U+00B0 "degree sign" (°) which
I think is the correct one to use.

This being said, there should be no difference between using the Unicode
code and actual "°" character (and I agree it's simpler to remember)

In [1]: a = u"Temperature, \u00B0C"
In [2]: a
Out[2]: u'Temperature, \xb0C'

In [6]: b = u"Temperature °C"
In [7]: b
Out[7]: u'Temperature \xb0C'


Coming back to your other question, I can't select the text in the PS
file (using Okular or Evince). (but PDF is selectable)

Also, the PS file renders properly with both "^(0)" and "°" signs. (but
with PDF, the "^(0)" is placed to low, while "°" is fine)

Best,
Pierre

Hi,

I have a time series data which I am using plot_time(). I am able to get a
legend and I also have axvspan to show weekends. However, how can I state
the "yellow" (axvspan) is a weekend on the legend or is there a better way
to show this?

This works fine. However it is easy to remember a superscript o then its
code :) By the way, can you select the text within the PS file?

Gökhan,

I tried your code, and everything worked fine for me. (PythonXY 2.7.3.1 
on Windows 7)
However, I usually use the escaped unicode value rather than unicode 
characters directly. Does the following work instead:

fp = plt.figure(figsize=(8.5, 11))
fp.text(0.5, 0.5, u"Temperature, \u00B0C", color='black', fontsize=16)
plt.savefig('test.ps <http://test.ps>', papertype='letter')
plt.savefig('test.pdf', papertype='letter')

Just a thought. Hope it helps.

Hello,

For some reason, I can't get the degree sign showing up in my ps output:

Here is the simple test code:

fp = plt.figure(figsize=(8.5, 11))
fp.text(0.5, 0.5, u"Temperature, ⁰C", color='black', fontsize=16)
plt.savefig('test.ps', papertype='letter')
plt.savefig('test.pdf', papertype='letter')

PS output shows Temperature, ?C, however PDF renders degree sign correctly.

I can't seem to select the text in PS output, but the text is selectable in
PDF.

This is probably a font issue, where PDF uses DejaVu, on the other hand PS
uses a Times type font.

So, how can I adjust matplotlib to save in PS file?

Thanks.
