[Matplotlib-users] plot legend title extension

[matthew a. <ma...@ca...>]

Hi

You might know that octave is a free software clone of matlab. I used it 
heavily for a previous project. One thing I liked about it's plot command 
is an extension to the fmt string which allowed you to specify the legend 
title for each line between semicolons. Like this:

plot(x, sin(x), 'r;sine;')
plot(x, cos(x), 'g;cosine;')
plot(x, tan(x), 'b;tangent;')

It seems like a handy way to be able to do things.

I couldn't see this mentioned in the matplotlib docs, and when I tried it 
I got a dialog "Unrecognized character in format string". May I suggest it 
as a useful addition to matplotlib? It seems like legend() might need 
adjustment to allow for it too.

BTW, using the GTK backend the "Unrecognized character in format string"  
dialog has locked up my python session after I clicked OK. It appeared
straight after the plot command -- not when I ran show(). After I clicked 
OK, the window stayed visible but unresponsive to the close button etc.
