[Matplotlib-users] ft2font error while building with python3 support
Dear list, I have been trying to build matplotlib with python2 *and* python3 support. I am using Gentoo and a custom ebuild which can be found on gnlay overlay[1]. However, I had a build error while trying to compile 'src/ft2font.cpp' (see the log attached[2]). I was wondering weather there are any preparation steps involved to make this file compile, which might be different from the python2 version? I found the 'CXX/Extensions.hxx' and the problem might be that it is not loaded due to some reason? I am afraid that this might have something to do with the my ebuild, so could someone tell me more about how the building process works? Or how much it is different for python3 compared with python2?

[Matplotlib-users] Performance after benchmarking seems low
Dear MatPlotLib users,
I am having trouble with the performance of matplotlib.
For data analysis, I want to be able to place multiple graphs on screen,
with multiple lines, each consisting of 16000 data points.
I have benchmarked my solution, but it did not perform too well.
For example: 6 graphs with 6 lines each, takes 12.5 seconds.
This graph indicates my benchmark:
http://img59.imageshack.us/img59/7613/graphpython.gif
I also noticed that memory usage during the benchmark rises to too high levels.
I have, during a different experiment, plotted 36 graphs with 1 line.
This is about 9MB of total (x,y) data alltogether, but execution of the
benchmark
spikes 1GB of memory usage.
My question:
- Is this performance of matplotlib to be expected?
- Can it be improved in any way?
Thank you very much in advance,
Anne
The code I use for the benchmark
for nr_of_graphs in range (1,7):
for nr_of_lines in range(1,7):
root = Tk.Tk()
#nr_of_lines = int(argv[0])
#nr_of_graphs = int(argv[1])
m = myLinMultiPlot()
m.drawxy(test {0}L on {1}G.format(nr_of_lines, nr_of_graphs),
nr_of_graphs, nr_of_lines)
root.mainloop()
The code that plots the actual lines
class myLinMultiPlot(Tk.Toplevel):
def drawxy(self, test_name, plots, lines):
pointsize = 16000
figure = Figure(figsize=(2,1), dpi=100)
storage = []
axes_arr = []
for p in range(0,plots):
for li in range(0,lines):
shift = li * 100
axes = figure.add_subplot(plots,1,1 + p)

xarr = xrange(0,16000)
yarr = []

[Matplotlib-users] Basemap drawparallels failed issue
Hi,
I am a new user of matplotlib Basemap. I tried to draw the latitude with

integer values. (drawmeridian can work with small interval 0.1).
Does anyone have any idea to fix this issue?

I am afraid that this might have something to do with the my ebuild, so could someone tell me more about how the building process works? Or how much it is different for python3 compared with python2? For py2k it's just pythonX.Y setup.py build and then pythonX.Y setup.py install, if you want to install. ft2font.so is built during the build step. I believe it's the same for py3k. I actually don't know if it'll work if you say e.g. pythonX.Y matplotlib.git/setup.py build .. might be an mistake in either distutils or the matplotlib build engine which I don't know at all (if there are additions from the mpl side to building at all.). If I'm right a ``cd ./matplotlib`` should do the trick. :-) I believe it's rare to invoke the setup.py from another directory than that where it resides in. I don't know how to build ebuild scripts.

Notice that upon clear() the locators are most probably lost. gca() get the current Axes object. xaxis and yaxis are its Axis attributes. The locator defines where to set ticks. If it's the NoneLocator this is rather a stub to saying don't place ticks ever. But it's more clean than to force them directly to the empty list because it'll survive at least limit changes. I don't know if the manual method survives that. Otherwise it's also a matter of taste. From the docs I do not see that you could hand over the locators directly to the imshow call http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot.imshow. For the frame, if it really matters, you can set the ``edgecolor`` probably to 'none', literally with the quotes. There's a Figure object created when you create the plot, you can get it via gcf().

Confirmed with git master. This is a major bug. Eric Hmmm, the bug that I once reported before about the errorbar plots having black edges seems to be back for me as well... I wonder if this is related? Ben Root Looks like an alpha-handling bug. I think the mec='none' is setting edgecolor alpha to zero, which is setting the gc alpha to zero, which is clobbering the rgbFace.

Re: [Matplotlib-users] data free margin
I don't know if this will work for you, but in your situation I would probably just make another axis for the data with no y value. Like, a short squat axis directly below the main axis. -Jeff Thanks. That crossed my mind, but I never tried it yet. I thought it would take up too much vertical room in the display to have another axis just for what would likely be 1-2 data points worth of y-less data. I'd really want to not display the x axis for that one and just align it with the x axis of the main plot, but then the data points would be *below* the axis, and that would seem visually odd. I'll play with it in a sample app and see if I can get it to look good this way.

Re: [Matplotlib-users] markeredgecolor (mec) in the plot function not working?
