matplotlib-devel Mailing List for matplotlib

First of all I just committed a generalized SpanSelector widget that
allows for a horizontal or vertical selection.

I am running into a problem (and HorizontalSpanSelector suffered from
the same problem) that the rect is drawn incorrectly if I adjust the
sublot params.  Any of the MPL transforms experts know what I need to
do?

Thanks,

After adding the paths for cygwin to 'basedir' in setupext.py (see
attached patch), I can now compile matplotlib 0.84 under cygwin. I do
however have problems with Tk.


I get the following error if I try to compile with Tk:

c++ -shared -Wl,--enable-auto-image-base

collect2: ld returned 1 exit status
error: command 'c++' failed with exit status 1



The problem with Tk, seems to comes from the fact that when it is
linked, the flags -ltk8.4 and -ltcl8.4 are used.

However, although /usr/lib/tk8.4 exists, the libs seem to be '84', not 
'8.4':

$ ls -l /usr/lib/libtk*
lrwxrwxrwx  1 walker Users      9 Feb 29  2004 /usr/lib/libtk.a -> libtk84.a
-rwxr-x---+ 1 walker Users 490984 Sep  2  2003 /usr/lib/libtk84.a
lrwxrwxrwx  1 walker Users     13 Feb 29  2004 /usr/lib/libtkstub.a -> 
libtkstub84.a
-rwxr-x---+ 1 walker Users   2058 Sep  2  2003 /usr/lib/libtkstub84.a


If I link  with the flags -ltk -ltcl, then it all seems to work:

  c++ -shared -Wl,--enable-auto-image-base 
build/temp.cygwin-1.5.18-i686-2.4/src/_tkagg.o

-lz -lstdc++ -lm -lpython2.4 -o 
build/lib.cygwin-1.5.18-i686-2.4/matplotlib/backends/_tkagg.dll



I'm not sure if this is a bug in the tcl/tk implementation on cygwin,
or a problem with matplotlib.

PS Cygwin doesn't come with things like numeric - these have to be 
compiled separately
