matplotlib-devel Mailing List for matplotlib

In case anyone is interested, it looks like the new config package is working 
with traits 3. This morning I uninstalled my enthought-2.whatever packages 
and installed etsconfig-2.1 and traits-3 from enthought's svn trunk (using 
the usual python setup.py install, not easy_install). backend_driver.py ran 
without errors.

Hi, here a message I sent a while ago, but I hanen't seen it on the
ML, so here it is again, in case.

Thanks,

Here is a simple patch that allow to make legend and its compnents
(texts, patches and lines) pickable for real.

The goal was to make this work (may be added to examples in mpl):

from pylab import *

N=100

props = dict( alpha=0.5, faceted=False )

fig=figure()

handles = []
colours = ['red', 'green', 'blue', 'magenta', 'cyan', 'yellow']

for colour in colours:
    x, y = rand(2,N)
    s = 400.0 * rand(N)
    handles.append(scatter(x, y, c=colour, s=s, picker=True, **props))

l = legend(handles, colours, )

grid(True)

for lb in l.get_texts():
    lb.set_picker(True)

def pick(event):
    a = event.artist
    if isinstance(a, matplotlib.text.Text):
        name = event.artist.get_text()
        h = handles[colours.index(name)]
        h.set_visible(not h.get_visible())
        draw()

fig.canvas.mpl_connect('pick_event', pick)
show()

 

PS: note that I am not on the mpl-devel  mailing-list. Please Cc me
