Dear SUMO community,

Happy new 2016!

I am experiencing problems while trying to visualise aggregated edge states on 
a map. I am using plot_net_dump.py and I have made sure 1) I have set 
<SUMO_HOME> for sumo-0.23.0; 2) I have installed matplotlib and Python. The 
command in cmd I am using is very similar to the one in the examples in 
http://sumo.dlr.de/wiki/Tools/Visualization .

The traceback I am getting is:

File "plot_net_dump.py", line 199, in <module>
                sys.exit(main(sys.argv))
File "plot_net_dump.py", line 178, in <module>
                sm = matplotlib.cm.ScalarMappable(cmap=get_cmap(
NameError: global name 'matplotlib' is not defined

Any suggestions what I might be doing wrong?

I apologise if this is a common problem, but I couldn't find anything relevant 
in the mailing lists.

Needless to say, any help will be greatly appreciated!
