[Matplotlib-users] STIX font baseline shifted in screen and png backend
Hi! Using the STIX fonts, the baseline of mathtext glyphs is corrupt using screen backands like GTK or TK. The problem does not appear using the ps or pdf backend. Attached is png and eps file of a semilogy plot with a mathtext xlabel. The ytick labes and the xlabel are skrewed in the png. Best wishes!

Re: [Matplotlib-users] MatPlotLib + Py2exe, backend problems ...
I *finally* got this to work!!! Thanks to Werner's message, I found the culpit: the matplotlibrc file copied to the dist directory contains the TkAgg backend. All I had to do is to change *that* file to say: backend : WXAgg Note that it's not the matplotlibrc in the installed copy - but the one in the resulting dist directory. In addition, I have to do a: set MATPLOTLIBDATA=.\mpl-data before I start the exe file. I don't know why this is necessary because the code for _get_data_path appears to look at that directory by default but if I don't set this, it can't find the data files. In any event, it works now - after bumping head for 2 weeks! Thanks everybody. > -Original Message- > From: Werner F.

[Matplotlib-users] subplots with linked axes
I would like to plot two or three graphs as subplots in a figure and control the axes such that when one graph is zoomed the others are adjusted too. I was hoping there would be a notification mechanism which would allow me to catch a rescaling of one subplot and redraw the others in step. Can anyone suggest a method of doing this?

Re: [Matplotlib-users] automatically choose line markers/styles?
Just an idea: Maybe you could also auto cycle between dash types if only the colour and not the dash type is specified in a plot command. The gnuplot default would be one model, or the predefined patterns in CorelDraw or Inkscape etc. Personally I don't see this as a high priority though.

Re: [Matplotlib-users] STIX font baseline shifted in screen and png backend
Yeah -- the hinting doesn't seem work very well with the STIX fonts. I may need to expose an option in the font backend to turn hinting off.

Note in matplotlib.__init__.py, it looks at a different folder if it is frozen by py2exe or py2app or ...: # py2exe zips pure python, so still need special check if getattr(sys,'frozen',None): path = os.path.join(os.path.split(sys.path[0])[0], 'matplotlibdata') So, if you use the sample setup.py I posted a while ago here and on the wxPython list it will create the matplotlibdata folder in your distribution (basically a copy of your mpl-data folder) folder. > before I start the exe file.

It sounds like what you want is to use the "shared axis" functionality.

Re: [Matplotlib-users] MatPlotLib + Py2exe, backend problems ...
Ok, I know what the problem is. I was using a sample setup.py posted by Stef and in his setup, he created a "mpl-data" subdirectory under "dist" to store all of the data files use by matplotlib. That's why matplotlib couldn't find it without a set statement. After changing the name to "matplotlibdata", everything works. I also made changes to every one of the matplotlibrc file I found in the installed copy of matplotlib to invoke WXAgg - instead of TkAgg. So for completeless, may be this will benefit other matplotlib users, here's my py2exe script - tested using python 2.3, latest wxpython and so forth. Let say you wish to create an exe of the sample multicolor.py program. Place multicolor.py in a test\multicolor directory, and a copy of the following script, have py2exe installed, and then just run it. You will end up with a dist subdirectory under test\multicolor and that's where you'll find multicolor.exe. # Kill_Distro = True MatPlotLib_Wanted = True def File_Exists( path ): res=os.path.isdir(path) if res==True: return res return os.path.isfile(path) from distutils.core import setup import py2exe import sys import os import shutil import glob homedir= r"E:\test\Matplotlib\multicolor" python = r"c:\Python25" # Name of python directory if File_Exists(python)==False: python = r"c:\Python23" # Name of python directory # *** # Some suggests that old build/dist should be cleared # *** dist_paths = [ homedir+'\\build', homedir+'\\dist' ] for path in dist_paths : if File_Exists ( path ) : shutil.rmtree ( path ) # *** # *** # *** data_files = [] packages = [] includes = [] excludes = [] dll_excludes = [] data_files.append ( ( '', glob.glob ( 'templates_*.*' ) ) ) # *** # For MatPlotLib # *** if MatPlotLib_Wanted : import matplotlib includes.append ( 'matplotlib.numerix.random_array' ) packages.append ( 'matplotlib' ) packages.append ( 'pytz' ) def mpl_data_files(destpath, path): mpl_data=[] for x in glob.glob (path+'\\*.*' ): if os.path.isdir(x): mpl_data_files(destpath+'\\'+os.path.split(x)[1], x) elif os.path.isfile(x): mpl_data.append(x) data_files.append ( ( destpath, mpl_data)) mpl_data_files(r'matplotlibdata', python+r'\Lib\site-packages\matplotlib\mpl-data') data_files.append ( ( r'matplotlibdata', glob.glob ( python+r'\Lib\site-packages\matplotlib\mpl-data\matplotlibrc' ))) data_files.append ( ( r'matplotlibdata\images', glob.glob ( python+r'\Lib\site-packages\matplotlib\mpl-data\images\*.*' ))) data_files.append ( ( r'matplotlibdata\fonts\afm', glob.glob ( python+r'\Lib\site-packages\matplotlib\mpl-data\fonts\afm\*.*' ))) data_files.append ( ( r'matplotlibdata\fonts\pdfcorefonts', glob.glob ( python+r'\Lib\site-packages\matplotlib\mpl-data\fonts\pdfcorefonts\*.*'))) data_files.append ( ( r'matplotlibdata\fonts\ttf', glob.glob ( python+r'\Lib\site-packages\matplotlib\mpl-data\fonts\ttf\*.*' ))) excludes.append ( '_gtkagg') excludes.append ( '_tkagg' ) excludes.append ( '_agg2' ) excludes.append ( '_cairo' ) excludes.append ( '_cocoaagg' ) excludes.append ( '_fltkagg' ) excludes.append ( '_gtk' ) excludes.append ( '_gtkcairo') excludes.append ( 'backend_qt' ) excludes.append ( 'backend_qt4') excludes.append ( 'backend_qt4agg' ) excludes.append ( 'backend_qtagg' ) excludes.append ( 'backend_cairo' ) excludes.append ( 'backend_cocoaagg' ) excludes.append ( 'Tkconstants' ) excludes.append ( 'Tkinter' ) excludes.append ( 'tcl' ) excludes.append ( "_imagingtk" ) excludes.append ( "PIL._imagingtk" ) excludes.append ( "ImageTk" ) excludes.append ( "PIL.ImageTk" ) excludes.append ( "FixTk" ) dll_excludes.append ( 'libgdk-win32-2.0-0.dll' ) dll_excludes.append ( 'libgdk_pixbuf-2.0-0.dll' ) dll_excludes.append ( 'libgobject-2.0-0.dll') dll_excludes.append ( 'tcl84.dll' ) dll_excludes.append ( 'tk84.dll' ) dll_excludes.append ( 'tclpip84.dll' ) # *
