Hello,
I am having problems using the visualization tool plot_net_dump.py, and I was
wondering if you could help me out.
I am using this command:
>python plot_net_dump.py -v -n eichstaett.net.xml -i
>emissionStats.xml,emissionStats.xml
and I just get the following:
Reading network from 'eichstaett.net.xml'
Reading colors from 'emissionStats.xml'
Reading widths from 'emissionStats.xml'
>
No plot! :S
I already tried to change the measures using speed, co2, nox, but I get the
same result.
I tried to put some flags inside the .py file to see where it stops and I saw
that it never enters the for "for t in times" since times is empty:
-----
times = []
hc = None
if options.dumps.split(",")[0]!="":
if options.verbose: print "Reading colors from '%s'" %
options.dumps.split(",")[0]
hc = WeightsReader(options.measures.split(",")[0])
sumolib.output.parse_sax(options.dumps.split(",")[0], hc)
times = hc._edge2value
print times
hw = None
if options.dumps.split(",")[1]!="":
if options.verbose: print "Reading widths from '%s'" %
options.dumps.split(",")[1]
hw = WeightsReader(options.measures.split(",")[1]
sumolib.output.parse_sax(options.dumps.split(",")[1], hw)
times = hw._edge2value
print times
for t in times:
"It never enter the for since times is times is{}"...
------
I printed times before getting into the for and this is what I got:
Reading network from 'eichstaett.net.xml'
Reading colors from 'emissionStats.xml'
Reading widths from 'emissionStats.xml'
{}

I don't think it is a issue with matplotlib because I can use other tools like
plot_net_speeds.py, plot_net_trafficLights.py or plot_summary.py
emissionStats.xml is a bit large but if you need it I can share it... I did
check that all the brackets were closed though.
This is an extract from emissionStats.xml:
<emission-export>
