[GRASS-dev] Re: [GRASSGUI] New profiling module for wxgrass

Tue May 22 05:28:35 EDT 2007

Working fine here (Xubuntu 7.04). I installed all num*py stuff
(numarray, numpy, numeric).

Really nice the possibility to zoom in and out of the plot (at least
for me the left button was zoom in and the right button was zoom out).

Wishlits: export the plot in some vectorial format, such as svg, so we
can put that in a drawing program for final editing.

PS: I get this error when I tried to set the region from display:

Set region from display:

Traceback (most recent call last):

    p = Popen(cmd, stdin=PIPE, stdout=PIPE, stderr=PIPE, close_fds=True)
NameError: global name 'Popen' is not defined
