Re: [Matplotlib-users] speed up imports?
Slow on my OSX machine as well. I also get this strange warning which I
have never seen before (I usually only use MPL on my windows machine).
Warning (from warnings module):
File
"/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/pytz/__init__.py",
line 29

UserWarning: Module numpy was already imported from

Re: [Matplotlib-users] speed up imports?
import pytz only took 0.0 seconds.
I actually just ran that pstats module and there is one line that stuck out
at me:
ncalls tottime percall cumtime percall filename:lineno(function)
10.0000.0000.0000.000
C:\Python26\lib\os.py:35(_get_exports_list)
5603.1070.0063.1070.006 {open}
That is ~50% of the load time. I have 0 idea what this is though.
Let me try this on my os machine.

[Matplotlib-users] speed up imports?
Has anyone had any success in speeding up the mpl imports? "import matplotlib.pyplot as plt" ( or "from matplotlib.figure import Figure") takes 6 full seconds to load. That seems excessive. Any ideas? -Andy -- Download Intel® Parallel Studio Eval Try the new software tools for yourself. Speed compiling, find bugs proactively, and fine-tune applications for parallel performance.

Re: [Matplotlib-users] Top/Right Tick Labels
So twiny() is up and running with a FixedLocator and Formatter for the ticks
on the upper xAxis but am now unable to rotate these tick labels. Is there
a special method to set the rotation, etc with FixedLocators?

Re: [Matplotlib-users] Top/Right Tick Labels
Turning label2On = true turned on the labels as directed. However, the
function label2.set_text("New Tick Label") does not update the
actual text. I can set_size(), etc and it works, but set_text() does not
update. Any ideas why?

[Matplotlib-users] Top/Right Tick Labels
Can someone point out how to simply label the ticks on the top and right of
a plot? twinx() and twiny() are not necessary because I don't need
independent scales and the mpl_toolkits.axes_grid.parasite_axes module is a
bit too limiting for my purposes.
(Part of my confusion stems from the fact that I can access the Tick
instances on the Axis but when I call Tick.set_label2("New Label") the label
does not get drawn. Perhaps I am being daft.)
Thanks in advance.
-Andrew

Re: [Matplotlib-users] Unknown Path Error
I spent some time trying to cobble one together but it was taking too much time so I tried the following and it seems to work now: Instead of using a thick line2D and adding it to the drawing, I added a patches.Rectangle instead. The line2D works in 0.88.5 but not in 0.99. The newer version was tripping over the Artist.contains() function call when used with line2D.

[Matplotlib-users] Unknown Path Error
I recently re-installed matplotlib (0.99) on my vista machine and my code that worked yesterday (no changes) no longer runs because of the following matplotlib error: File "C:\Python25\Lib\site-packages\matplotlib\lines.py", line 286, in contains path, affine = self._transformed_path.get_transformed_path_and_affine() AttributeError: 'NoneType' object has no attribute 'get_transformed_path_and_affine' All I am doing is initially drawing a line2D (which works) and then testing if line2D.contains(event)==True if I mouse over the line.

[Matplotlib-users] Align Text (Relative)
I am currently using the annotate() method for my data points and I was curious if there is a way to center a line of text relative to a line of text below it. I am currently using two annotate() function calls in a row (I need the text to be different colors) but I need the first one to act as a title for the second (i.e. so I want it centered relative to the one below.) I have tried to use the length of the second bit of text to center but I just cannot seem to do it. The code looks sort of like this: import matplotlib.pyplot as plt ... annotateTitle='Title' annotateText='Blah, Blah, Blah' plt.annotate(annotateTitle, xy=(1,1), xytext=(20,50), xycoords='data', textcoords='offset points') plt.annotate(annotateText, xy=(1,1), xytext=(20,20), xycoords='data', textcoords='offset points', size='small', color='black') Any ideas? -Andy -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

[Matplotlib-users] Dog Ear?
Hello,I am relatively new to matplotlib but I get the basics. What I need to do though is a slightly customized graph area. There are two plots on the same graph - a parabola and a straight line (with a negative slope) north east of the parabola. This graph has grid lines. Simple enough, but now I want to remove the graph area to the right of the line. Think of a dog-eared page in a book. Basically that top right triangle is gone. Can I do this in MPL or do I need to do some post processing in PIL? Much thanks for any help. -Andrew -- This SF.net email is sponsored by: High Quality Requirements in a Collaborative Environment.
