How to add text descriptors to highlighted regions in the circular graph?

[tlnagy]

I have a graphic that is very dense and it's hard to distinguish between the leaves so I wanted to label over each colored region to indicate what they are:

How could I do this? I would prefer to label over the individual regions themselves, but a legend would work as well. I'm coloring the regions using NodeStyle's background color property.

Thanks for the help! -t

Hi Tamas,

region labels are not implemented yet, although the feature is in the roadmap for future versions.

Adding a legend is possible using the TreeStyle.legend, which is a FaceContainer object. You can use TreeStyle.add_face(...) and then place the full block in any of the four corners of the image (TreeStyle.legend_position).

Something like this: http://pythonhosted.org/ete2/tutorial/tutorial_drawing.html?highlight=legend#add-legend-and-title

cheers, jaime

PS. I am CCing this question to the support mailing list

Using a simple legend will work for now. Thanks!
