Accessing colors

Hi all,

How can I access the (r, g, b, alpha) tuples used by default when using graph_draw()?

Thanks

The default color map used can be accessed via:

    graph_tool.draw.default_cm

Best,

The default color map used can be accessed via:

    graph_tool.draw.default_cm

I want to extract the exact colors used by default in coloring vertices. For example vertex_fill_color=0 is turquoise (graph_tool.draw.default_cm(0)), 1 is yellow (graph_tool.draw.default_cm(300)), ...

How can I access the exact colors used in graph drawing?

I need this to create a legend.

Thx

Haiko

The default colors are extracted from that color map, by normalizing the
property map values into the color map's range. In other words, the
smallest value will correspond to the first color, and the largest value
to the last color.
