Re: [Matplotlib-users] Newbie : How to add a Colored legend with Text for 3d plot

[hari j. <ha...@gm...>]

Thanks a lot John and Benjamin for your help.

The Proxy Artist approach fits the bill perfectly.

I used the following code to make a legend from my color_lut lookup table.


# Lookup table for color
col_lut = dict(Bistris7p2 = "burlywood", Cit7p2 = "c",APhosph8p0 = "m",
Acetate5p5 = "k",Borate8p5 = "y",Mes6p7 = "c",Hep8p2 = "g",ATris9p0 = "r")

for key,value in col_lut.items():
    legend_box.append(Rectangle((0,0),1,1,fc="%s" % value))
    legend_text.append(key)
ax.legend(legend_box, legend_text)
