[Matplotlib-users] stacked bar and a table
Hi,
I have to problems when using a table with bar.
On the first one I use this code:
for row in xrange(rows):
bars = axes.bar(ind, yearValues[row], width, bottom=yoff,
color=colours[row])
yoff = yoff + yearValues[row]
cellText.append(['%d' % (round(x*1.0, 0)) for x in
yearValues[row]])
axes.set_xticks([]) # remove the default ticks
axes.set_ylabel(labelDesc)
# Add a table at the bottom of the axes
the_table = axes.table(cellText=cellText,
rowLabels=rowLabels, rowColours=colours,
colLabels=colLabels,
loc='bottom')
the_table.set_fontsize(10)
My problem is that the bars are taking up to much space and only a
portion of my table is shown.
My second problem uses this code:
for row in xrange(rows):
# purchase values
bars = axes.bar(ind, yearValuesP[row], width, bottom=yoffP,
color=colours[row])
yoffP = yoffP + yearValuesP[row]
# consumption values
bars = axes.bar(ind, yearValuesC[row], width, bottom=yoffC,
color=colours[row])
yoffC = yoffC + yearValuesC[row]
cText = []
for x in range(len(yearValuesP[row])):
xP = round(yearValuesP[row][x], 0)
xC = round(yearValuesC[row][x], 0)
xN = xP + xC
cText.append('%d - %d = %d' % (xP, -xC, xN))
cellText.append(cText)
# add a line to mark zero
axes.axhline(linewidth=4, color='k')
# add a line for net change
netVal = yoffP + yoffC
aLine = axes.plot(indNet, netVal, 'o-', color='blue', linewidth=4)
autolabelLine(aLine, axes)
axes.set_xticks([]) # remove the default ticks
axes.set_ylabel(labelDesc)
# Add a table at the bottom of the axes
the_table = axes.table(cellText=cellText,
rowLabels=rowLabels, rowColours=colours,
colLabels=colLabels,
loc='bottom')
the_table.set_fontsize(10)
Here the full table is shown but the text is too small to read.
In both cases I tried 'axes.autoscale(tight=True)' and played with the
font size but with no success.
Would appreciate any tips on what I may do wrong or what else I need to
do to have things show correctly.

Re: [Matplotlib-users] What backends are working with python 3
Hi Jorge, Oops, sorry for first sending it directly to your mail. Some time ago I did a bit of work on the wx backend to work with wxPython Phoenix. https://github.com/matplotlib/matplotlib/pull/2803 I haven't had time to look at the last few comments made on that PR. Just the other day someone contacted me off list and he used it on a project of his with a recent build of Phoenix. He noted small refresh issues which corrected itself by resizing the frame, this probably needs a "self.Refresh" or similar when things get drawn. Builds for Phoenix are here: http://wxpython.org/Phoenix/snapshot-builds/ Recent versions of Phoenix (this is still in development) run on Py 2.7, Py 3.3 and Py 3.4 and use the wheel format and can be installed with the following at least on Windows and Mac as far as I know: pip install -U --pre -f http://wxpython.org/Phoenix/snapshot-builds/ wxPython_Phoenix Werner -- Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.

I would like to have the percentage values shown in white instead of in black within a pie chart. I figured I could do something like: def reColor(percent): "I am lost here on how to format the percentage and change the color" axes.pie(values, labels=labels, autopct=reColor, shadow=False, colors=colors) I thought I could use a mpl.text.Text but I only get the percentage in "reColor".

The following code is doing what I want, but it does not feel right.
myPie = axes.pie(values, labels=labels, autopct=u'%1.0f%%',
shadow=False, colors=colors)
for x in myPie[2]:
x.set_color('w')
Is there really no "cleaner" way of doing this?

[Matplotlib-users] mpl 0.99 and py2exe
I have run into a bit of problem using 0.99 and py2exe. I am getting errors "TypeError: unsupported operand type(s) for +=: 'NoneType' and 'str'" in mlab.pyo after py2exe'd my application. This is caused by this type of code, as one normally uses the optimize option with py2exe which means that the docs are stripped from the .pyo files. "psd.__doc__ = psd.__doc__ % kwdocd" I changed it to: if psd.__doc__ is not None: psd.__doc__ = psd.__doc__ % kwdocd else: psd.__doc__ = "" Above is a bit of a hack, if someone can suggest how to correct this in a way which would get accepted as a patch I would search all modules correct them.

I documented what is needed for a py2exe setup.py with mpl 0.99 on the py2exe site at the end of the following page http://www.py2exe.org/index.cgi/MatPlotLib . While doing this I noted one more problem if one uses backend_wx, the wxPython version check will always fail if py2exe'd. I added "if not hasattr(sys, 'frozen'):" on line 113 and indented lines 114 to 131. Hopefully someone could make this change for the next version of mpl.

[Matplotlib-users] does mpl.canvas has a flag "needsdrawing"?
I have multiple canvas and sometimes one or more might have nothing to
draw (no data).
Currently I just call.
canvas.draw()
canvas.Refresh()
for each of the canvas, but this gives me an error if there is no data.
Is there a built-in flag I can check before calling draw? Or do I have
to keep create my own?

There is no such flag, but you should not get an error on drawing an
empty figure or one that doesn't "need" to be drawn. Can you post
example code that produces the error?
I narrowed it down to one line of code, if I comment the following line
then the error goes away.
axes.xaxis.set_major_formatter(yearFmt)
Is this enough for you? Or do you like some runnable code?

[...] Hi, Werner. I've been running the release candidate of Windows 7 and haven't encountered that issue. Same here, I had no problem with the RC, but frankly did very little work with it. My Python installation is that of Python(x,y) 2.1.17, which includes the same version of Python as yours, and I'm using a build of matplotlib from SVN, although I previously used version 0.99.0 without DLL trouble. On my machine, I found msvcp71.dll in several directories under C:\Python25\Lib\site-packages (including site-packages\wx-2.8-msw-unicode\wx), in C:\Windows\System32, and in several locations under C:\Program Files, but not in C:\Python25. There is a similarly-named msvcr71.dll in C:\Python25. I have both "p" and "r" of msvcX71.dll. I'm wondering whether and how msvcp71.dll is related to the traceback to the _path module, because the _path module comprises a .pyd (~= .dll) file.

It looks like I run into a similar issue on a client machine.
He is on Windows XP SP 2 Suisse edition and he gets "Unhandled
Exception" error which does not show any traceback.
My application is py2exe'd, so I did another build using 0.98.5 (both
with numpy 1.3, Python 2.5.4 and wxPython 2.8.10) but now at least we
get a traceback:
Traceback (most recent call last):
File "appwine.pyo", line 939, in OnToolbarChart
File "zipextimporter.pyo", line 82, in load_module
File "frameplotmpl.pyo", line 24, in
ImportError: cannot import name FigureCanvasWxAgg
The relevant section of frameplotmpl.py is:
from numpy import arange, sin, pi
import matplotlib as mpl
# following is already done on stats page
##mpl.use('WXAgg')
from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg as FigureCanvas
from matplotlib.backends.backend_wx import NavigationToolbar2Wx
from matplotlib.dates import YearLocator, MonthLocator, DateFormatter
from matplotlib.ticker import FormatStrFormatter
from matplotlib.font_manager import FontProperties
What is really strange I can run the same .exe on my XP test machine which is
running XP SP2 English without any problems.
I know there is not much to go by here, but would very much appreciate if
anyone has some hints/tips on what I should look at (note that the client is
non technical and I have no access to his machine).

Re: [Matplotlib-users] 0.99.1 crashes python on Windows XP [SEC=UNCLASSIFIED]
Using numpy with "/arch nosse" solved the issue.
Probably OT here, but does anyone know if numpy will in the future be
able to dynamically switch on/off the SSEx support?

Hi Kim,

Hi group,
I have previously had success with py2exe and matplotlib, using a
specialized setup.py like the attached one (which is adapted from
http://www.py2exe.org/index.cgi/MatPlotLib).
However, now I have tried to go a step further and integrate some
Tkinter controls in the GUI for a prototype, see attached alphabeta.py
If I do a python setup.exe py2exe with this setup file on the attached
Tkinter/matplotlib and alphabeta.exe is successfully created.
However, it does not run for everyone else:
Myself: Works like a charm
A user with a python environment who make py2exes himself: Crashes on
startup with the attached error log
A user with just a Python environment: Works!
A user with no Python environment: Crashes on startup with the same log.
The log does not give me any good ideas as to how I could modify
setup.py to get it working.
Any good ideas?
Changing the line 560 in mathtext.py from:
font = FT2Font(basename)
to:
font = FT2Font(str(basename))
Fixed it for me, I don't know what FT2Font does and why this matters -
hopefully someone else can expand on this.
Attached your setup.py a bit simplified as you are using matplotlib 0.99.

This worked here as well - sort of, at least. It was just a guess, as I noticed that the other call to FT2Font is using str too. It does not crash anymore, but the LaTeX $\alpha-\beta$ in the title is not rendered correctly in the title of the graph for the users who had problems before. Yeap, I see this now too. I guess it must be due to some fonts not being available in the dist, which are available to me and others. I do not know if there is a way to patch up setup.py such that the needed fonts are included in the dist? It should be there, i.e. mpl-data in the lib/site-packages/matplotlib folder has the same number of files and folders as the one created by setup.py in dist. But it obviously doesn't find it or some other setting to handle the LaTex stuff is not there. Put this at the top of alphabeta.py, i.e. just after import matplotlib matplotlib.verbose.level = u'debug' and change setup.py to generate a console app. If I run this on my dev machine the output shows that fonts are found, but if I run it on the py2exe'd version lots of STIX fonts are not found. Even so these fonts are in mpl-data/fonts/ttf of the py2exe dist folder. So, I think/guess that the font searching is not done correctly, as running with verbose "debug" it shows that it finds the mpl-data folder in the dist folder or wherever you copy dist too. Hopefully someone who knows how the font searching is done can help out/point to the culprit. Attached your setup.py a bit simplified as you are using matplotlib 0.99. Thank you.

[Matplotlib-users] text element just above previous text element
I like to have 2 or 3 text elements "stacked" on top of each other on top of a bar. Currently it works for the first text element by doing: height = bar.get_height() xCorr = bar.get_x() yCorr = 0.20 + height txtax = axes.text(xCorr, yCorr, hstr) trying to add the second text just above the previous one I tried this: pCorr = yCorr + txtax.get_size() + 0.4 txtax = axes.text(xCorr, pCorr, hstrPerc) It looks like my problem is that get_x() returns a value in ticks and txtax.get_size() is in pixels and I can't find a way to get at the height of the text element in ticks.

Re: [Matplotlib-users] text element just above previous text element
Finally figured it out after pulling some hear. Using "axes.annotate" instead of "axes.text" worked for me, i.e. something like this: axes.annotate(hstr, xy=(xCorr, yCorr), xytext=(0, 5), textcoords='offset points') instead of what I did originally.

[Matplotlib-users] numpy and matplotlib 0.87
I got this to work, only issue left is the py2exe problem (see other post). Looking through the matplotlib 0.87 doc (page 13) it mentioned that one should use an appropriate package for the numeric package one uses, but I can't see see these packages. Is it that the doc is just a bit out of date? FYI, the section 1.2 Numerix does also not mention numpy. Werner Using Tomcat but need to do more? Need to support web services, security?

Can not get it to work with numpy (see other thread), however using
Numeric with the following py2exe setup.py sections looks like it works
even using an Ansi wxPython version (my app uses a database, while I am
planning to switch to Unicode, I don't have time for this at the moment).
The matplotlib related entries in the options section are "pytz" and
"matplotlib.numerix" and the exclude of the wxmsg26uh_vc.dll".
# options for py2exe
options = {"py2exe": {"compressed": 1,
"optimize": 2,
"packages": ["encodings",
"kinterbasdb",
"pytz", "matplotlib.numerix",
],
"excludes": ["MySQLdb", "Tkconstants", "Tkinter",
"tcl",
"orm.adapters.pgsql",
"orm.adapters.mysql"
],
"dll_excludes": ["tcl84.dll", "tk84.dll",
"wxmsw26uh_vc.dll"]
}
}
zipfile = r"lib\library.zip"
And this is the setup section (with some stuff omitted):
setup(
classifiers = ["Copyright:: Werner F. Bruhin",
...
"Natural Language :: English"],
windows = [twcb],
#console = [twcb],
options = options,
zipfile = zipfile,
data_files = [("prog\\locale\\fr\\LC_MESSAGES",
mylocaleFR),
...
matplotlib.get_py2exe_datafiles(),
("prog\\amaradata", amaradata),
("prog\\amaradata\\Schemata", amaraschemata),
]
)
I am using py2exe 0.6.5, wxPython 2.6.3.2 and Python 2.4.
Need to do further testing with it, but the matplotlib plots (some line
and pie charts - nothing very sophisticated) work fine.
Will give numpy another try, if I get some hints on how to overcome the
issue reported in another thread.

I have only Numeric and numpy on my system. I only need one, just wanted to get up to date, so tried changing from Numeric to numpy. For testing I rename the folder of the one I don't want to use, so py2exe nor matplotlib can not find it. I don't have a real need to change, so for the moment I will stay with Numeric and if I don't run into other problems with matplotlib 0.87.3 I stay with it otherwise I will go back to the version I used before and upgrade when I get around to move over to wxPython Unicode.

[Matplotlib-users] matplotlib 0.87.6 and wxPython
Second sending (to list instead of gmane) - sorry if this gets through twice, but sent it yesterday and until this morning would not see it. I am including indiv. files instead of zip (maybe zip's are blocked?). Just downloaded the latest build to start testing my things with Python 2.5. I also installed the examples.zip for 87.1 and found that they were still using "from wxPython import *" which is deprecated as of wxPython 2.7. I upgraded some of them to "import wx" and included them in the attached zip file, there are some (using XRC which I did not upgrade as I don't know how the XRC stuff works, it also uses the old style import). Note that the "dynamic_image_wxagg.py" example does not close when clicking on the "X". Will keep looking and try to figure out why. Some of these examples give me the "wxmsg26uh_vc.dll" not found error. I thought having seen some messages explaining how to deactive the use of unibol version of wxPython but can't find it. BTW, will there be a build for Python 2.5 and wxPython 2.7 Unibol (which is what I used for testing - see below)?

Re: [Matplotlib-users] matplotlib version info
Stephen, On the dev list was an ANN post which stated that 0.87.7: This release is compiled against numpy-1.0 final. The binaries are fresh on sourceforge, so they may take some time to propagate to the mirrors. http://cheeseshop.python.org/pypi/matplotlib/ http://sourceforge.net/project/showfiles.php?group_id=80706&package_id=82474 Note: There is a compile error on python2.3 that will probably require a slight modification to the released source. Please allow some time for us to fix this and post the binaries.

For me the ideal would be not to be depended on a particular release of wxPython - big surprise no :-) . If I understand it correctly the dependency came in for performance optimization, does 2.8 change something for this. - If yes, I would not see a problem with 0.9 requiring as a minimum 2.8.0.1 but going forward I could use any 2.8.x or newer release. - If no, then I guess we have to live with having a "fixed" dependency, e.g. 0.87 is wxPython 2.6.x, 0.90 is wxPython 2.8.x, but it should through at least a warning if one tries to use it with another wxPython release.

Matplotlib 0.9 is still build against wxPython 2.6 and it is using the Unicode build of it. But I am surprised that you see crashes. I did a little bit of testing with wxPython 2.8, Python 2.5 and matplotlib 0.9 using the examples for matplotlib and did not see hard crashes (see the thread on the 14th).

Re: [Matplotlib-users] matplotlib and py2exe
Hi Archana,
Sometimes py2exe can't figure out what needs to be included. In these
cases one creates entries in the packages section to force the inclusion
of one or multiple packages.

You need to activate/un-comment the matplotlib.numerix line. Also note
that if you only include UTC and you use the timezone stuff in matplot
then a user NOT using UTC, i.e. another timezone will have a problem, it
is therefore better to just include all of pytz.

Re: [Matplotlib-users] matplotlib and py2exe
Hi Giorgio,
Had a quick look at pylab based scripts and got an error on
backend_tkagg when py2exe it. It looks like one needs to force the
backend to be included, I used tkagg but you would have to replace that
with wxagg for your script.
Attached is a setup.py and from the examples the file simple_plot.py.

The setup.py you are using will not work, it is meant for a matplotlib
embedded in wx, and even for that some lines are commented out.
Can you try the setup.py I sent yesterday with which I included
simple_plot.py, which is a script using pylab as you do in your trial.py.

Re: [Matplotlib-users] matplotlib and py2exe
Hi Emmanuel,
Maybe your problem has to do with your "enthought" build of wxPython. I
use standard builds from wxPython site.

You get two copies of matplotlibdata as you kept both of the two above
lines active. You need to use the first one of you use the py2exe
option to create a library.zip which I put into a sub-folder called
'lib' in the sample setup.py file.

You are also using an 'egg'. I seem to recall that py2exe does not yet
really support that, but you might want to check on the py2exe list
(e.g. on the gmane mirror of it at
http://dir.gmane.org/gmane.comp.python.py2exe

the above line does not look correct. I.e. the '+' in there, what is it
for?
I have a folder structure of
dist/lib
dist/prog
so this one works for me
("lib\\matplotlibdata", mpfiles), # use this line if use zipfile option
if one does not use the py2exe zipfile option, which I use, then this
should work
matplotlib.get_py2exe_datafiles(), # or this one if you don't use the
zipfile option
If one uses the zipfile option then all of the matplotlib stuff is under:
dist/lib
and it expects to have the data stuff in
dist/lib
otherwise it wants it in
dist

I don't know, but I think the setup.py I posted to this list for
"embedding_in_wx4.py" is pretty accurate and at least for me it does
build a matplotlib app.

If you use wxPython then as of 0.87.? something you need to either use wxPython 2.6 Unicode or rename the following file: matplot\backends\_wxagg.pyd to matplot\backends\_wxagg DO NOT USE.pyd (or something similar). The 0.87 version was compiled against wxPython 2.6 to take accelarate some functions, by renaming the above file you basically deactive this accelaration code. I believe the next version of matplotlib will get rid of this dependency.

Re: [Matplotlib-users] matplotlib and py2exe
Hi Robert,
If your app is wxPython based then I would use the attached as a test
case and not the simple_plot one.
Then if you don't use wxPython Unicode 2.6.x then you need to follow
Andrea's work around.
matplotlib/backends/_wxagg.pyd
to
matplotlib/backends/_wxagg not used.pyd
Hope this helps

The work around I did is using glob.glob instead as follows:
# matplotlib data
##mpdir, mpfiles = matplotlib.get_py2exe_datafiles()
mpfiles = glob.glob('C:\Python25\lib\site-packages\matplotlib\mpl-data\*.*')
But I can't confirm yet that this works as I am also trying out
something else in my InnoSetup script. Will confirm ASAP and will try
and look into matplotlib.get_py2exe_datafiles() and see how it could be
fixed.
Best regards
Werner

I have change matplotlib.get_py2exe_datafiles() to:
def get_py2exe_datafiles():
import glob
mplfiles = []
for item in glob.glob(os.sep.join([get_data_path(), '*/*'])):
if os.path.isdir(item):
mplfiles += glob.glob(os.sep.join([item, '/*']))
mplfiles.append(os.sep.join([get_data_path(), 'matplotlibrc']))
try:
mplfiles.remove(os.sep.join([get_data_path(), 'Matplotlib.nib']))
except:
pass
return ('matplotlibdata', mplfiles)
Now this creates a "flat" folder, i.e. all datafiles are directly under
matplotlibdata. In my tests this works for me in my limited tests, with
the exception that I also get the "Could not match Bitstream Vera
..etc" error - but this is something I also get with py2exe, so I
don't know if this is an issue.
Andrew, do you know if the sub-folder structure should be retained when
using py2exe for matplotlib to work correctly in all circumstances? If
that would be the case let me know and I try to come up with something.

Hi Andrew,

Dear Werner,
I am reluctant to eliminate the sub-folder structure because I think
it would add the possibility of unnecessary bugs to just the py2exe
built version. Would it be possible for you to re-factor this to
include the directory layout? When you test it, can you test some
interactive plot to make sure all the button icons are loaded properly?
I don't know how to change "matplotlib.get_py2exe_datafiles()" to retain
the folder structure. But in the attached setup.py I used
"matplotlib.get_data_path()" for each of the sub-folders and then define
the folder structure again in the py2exe "data_files" section. The
enclosed setup.py builds an exe for embedding_in_wx.py and I have no
problems running it and the toolbar shows all its icons.
I am also enclosing some example files which I have upgraded to the new
wxPython namespace - I had sent them some time ago but the examples.zip
file I just downloaded contains the old versions.
dynamic_demo_wx.py, namespace changes and a OnClose event to stop the
timer (otherwise the script can not be stopped by clicking on the X).
dynamic_image_wxagg.py, namespace changes
dynamic_image_wxagg2.py, namespace changes and removed numarray stuff.
embedding_in_wx.py, namespace changes
embedding_in_wx2.py, namespace changes
embedding_in_wx4.py, namespace changes
Can you update the zip file with the above files?
Best regards
Werner
