[Matplotlib-users] Any available backend for non-root users?

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Hi everyone. I have trouble to find a usable background on a remote server
where I do not have root privilege. Unfortunately, there is no backend
available:

               Tkinter: no
                        * Using default library and include directories for
                        * Tcl and Tk because a Tk window failed to open.
                        * You may need to define DISPLAY for Tk to work so
                        * that setup can determine where your libraries are
                        * located. Tkinter present, but header files are not
                        * found. You may need to install development
                        * packages.
                  Gtk+: no
                        * Building for Gtk+ requires pygtk; you must be able
                        * to "import gtk" in your build/install environment
       Mac OS X native: no
                    Qt: no
                   Qt4: no
                PySide: no
                 Cairo: no

The output of a simple script is
==================
simple_plot.py:
#
from pylab import *
plot([1,2,3])
show()
#
python simple_plot.py --verbose-helpful > output.txt
==================
$HOME=/ccs/home/user1
CONFIGDIR=/ccs/home/user1/.matplotlib
matplotlib data path
/ccs/home/user1/.local/lib/python2.7/site-packages/matplotlib-1.1.0-py2.7-linux-x86_64.egg/matplotlib/mpl-data
loaded rc file
/ccs/home/user1/.local/lib/python2.7/site-packages/matplotlib-1.1.0-py2.7-linux-x86_64.egg/matplotlib/mpl-data/matplotlibrc
matplotlib version 1.1.0
verbose.level helpful
interactive is False
platform is linux2
Using fontManager instance from /ccs/home/user1/.matplotlib/fontList.cache
backend agg version v2.2

When I tried to install pygtk, it requires glib, which is missing, and I
just did not digg further. So, is there any workaround that I can get ANY
backend to work (to show images on screen).

Any suggestions will be greatly appreciated (I really want to get things to
work).

Regards,
Liang
