Re: [sumo-user] Custom Colormap for Visualization

[Fabio Lamanna <fblamanna@xxxxxxxxx>]

Thanks Jacob. In the meantime, what's the exact meaning of the discrete colormap:

--colormap "#0:#0000c0,.25:#404080,.5:#808080,.75:#804040,1:#c00000"

Does it take five intervals (bins?) of input values and interpolate the colors among them? Is it possible as a workaround to have the same pattern but as discrete interval colors (e.g. green, yellow, orange, red, purple), without interpolation?

Thanks a lot.

Fabio

You can use option --colormap to pick among a large range of predfined maps: https://matplotlib.org/stable/gallery/color/colormap_reference.html

User-defined colormaps are not supported but pull-requests are welcome.

Hi all,
is it possible to pass to plot_net_dump.py and other scripts a custom colormap?
This might be created within matplotlib with ListedColormap(), like:

Thanks.
