Re: [sumo-dev] plot_net_dump visualization

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

Both files passed to the plotting script must cover the same time intervals. The first file is used for the colors and the second for the width (the same file may be used for both parts).

By passing two files with different time ranges to the script, no color and width data with the same timestamps are found.

It is not like there is no plot at all. By removing the limits it gets zoomed out.

It is plotted like this:

The problem is that it is not colored at all.

Also, the path I am using looks looks this:

python D:/prog/tools/visualization/plot_net_dump.py

Do you have any idea what might be?

Thank you!

Possibly, you are plotting an empty spatial range. Try running your command without --xlim and --ylim.  Also, the tool is located at SUMO_HOME/tools/visualization. If you put it someplace else it may not find it's libraries.

Hello,

I was trying to get a plot using plot_net_dump python script but it seems like nothing is plotted.

I used the following command:

python .SUMO HOME/plot_net_dump.py -v -n pr.net.xml --measures speed,entered --xlabel [m] --ylabel [m]  --default-width 0.5 -i  dumps_0_500.xml,dumps_500_1000.xml --xlim 300,1500 --ylim 1100,2300 --min-color-value -1000 --max-color-value 1000 --min-width-value -1000 --max-width-value 1000 --colormap seismic

And nothing gets colored on the map. I ran the simulation with a random traffic using random_trips.py and with this code for the additional file:

<edgeData id="dumps_0_500" freq="20" file="dumps_0_500.xml" excludeEmpty="true" begin="0" end="500"/>

<edgeData id="dumps_500_1000" freq="20" file="dumps_500_1000.xml" excludeEmpty="true" begin="500" end="1000"/>

The output file looks like this:

Do you know which may be the problem?

Thanks a lot,

Iulia
