I tried to replicate this problem and could not. I did a clean
install of 0.83.2 on windows XP for python23 and Numeric 23.7 and your
test script ran fine for me. That makes it harder to fix.
I reread your original post and you are getting the error
File "C:\Python23\Lib\site-packages\matplotlib\agg.py", line 809,
def move_to(*args): return _agg.path_storage_move_to(*args)
TypeError: argument number 1: a 'path_t *' is expected,
'path_storagePtr(<agg.path_storagePtr; proxy of C++
agg::path_storage instance at _208aa401_p_agg__path_storage>)' is
Is this the one you are still getting? For some reason it appears
that the SWIG typedef 'path_t' for 'agg::path_storage' is not being
properly handled on your system.
Can you provide any more information (exact operating system, other
things you've installed, any nonstandard path settings, etc). I
assume the script you posted is the one you are working with, and you
are not importing anything except pylab.
Here is what I am testing with
from pylab import *
xlabel('this is a xlabel\n(with newlines!)')
ylabel('this is vertical\ntest', multialignment='center')
#ylabel('this is another!')
text(2, 7,'this is\nyet another test',
horizontalalignment = 'center',
verticalalignment = 'top',
multialignment = 'center')
which I run with
C:> c:\Python23\python myscript.py -dAgg --verbose-helpful
