[Matplotlib-users] Matplotlib in Cygwin
Has anyone had any luck compiling Matplotlib using cygwin?
Out of the box I get the following: (I have numpy, tcl/tk and libpng1.2
installed)
~/matpl/matplotlib-0.98.3$ python setup.py build
BUILDING MATPLOTLIB
matplotlib: 0.98.3
python: 2.5.1 (r251:54863, May 18 2007, 16:56:43) [GCC

platform: cygwin

numpy: 1.2.0
freetype2: 9.18.3
OPTIONAL BACKEND DEPENDENCIES
libpng: found, but unknown version (no pkg-config)

841, in check_for_tk
explanation = add_tk_flags(module)
File "/cygdrive/c/linuxshare/matpl/matplotlib-0.98.3/setupext.py", line
1084, in add_tk_flags
result = parse_tcl_config(tcl_lib_dir, tk_lib_dir)
File "/cygdrive/c/linuxshare/matpl/matplotlib-0.98.3/setupext.py", line
946, in parse_tcl_config
tk_lib = tk_vars.get("default", "TK_LIB_SPEC")[1:-1].split()[0][2:]
IndexError: list index out of range
Any help or ideas appreciated!
Thanks,
Pete

Hi John,
Thanks - that's a help. TK_LIB_SPEC is apparently empty -
tk_vars.get("default", "TK_LIB_SPEC") returns ''. See attached patch for an
attempt to manage this condition.
This brings me on to my next problem.. here's the result of the patched
script. is this new error likely to be connected with the above issue?
(I'm using an up-to-date cygwin installation)

Re: [Matplotlib-users] failure with python setup.py build
See my previous posts, subject "Matplotlib in cygwin". I attached a patch in
that thread that solves this problem for me, but it looks like I have other
more serious problems with cygwin on my machine.
Please let us know if you get it to work.

[Matplotlib-users] heatmap with varying size boxes?
Hello, I have a list of X,Y coordinates and a ratio associated with each coordinate. The X and Y coordinates are continuous but random from 50-500, I would like to make a continuous heatmap of the ratios at each coordinate. One caveat is that the coordinates are clustered together do some bixes might have too little data. I am wondering if there is a way that R can automatically adjust box sizes?

[Matplotlib-users] 1d heat map
Hello List, I am trying to use the pylab.contourf(X,Y,Z,100) function but I would like to mplot a 1 dimensional heatmap instead of a 2 dimensional heatmap, Perhaps "contourf" is not the solution but I do like these plots.

I was able to use WxAgg instead. wxPython 2.8 did not work but switching to 2.6 cured that.
