when the same Line2D is plot on two subplots, it disappears on the two subplots

Hi,

I use matplotlib 0.91.2.
When I plot the same Line2D on two subplots, it disappears: execute the
following script:

···

#######################
from pylab import *
ion()
f = figure()
s = f.add_subplot("211")
curve = matplotlib.lines.Line2D([0,1],[0,1],color='m')
s.add_line( curve )
s2 = f.add_subplot("212")
draw()
raw_input('press a key to delete a line to second subplot')
s2.add_line( curve )
s2.lines[-1].figure.canvas.draw()
print s2.lines[-1].get_visible()
raw_input('press a key to quit')
#######################

What is the reason for this behavior?

Thanks

Julien

PS: thanks to Friedrich Hagedorn for his correction of my signature.

The lines get their transforms from the axes they reside in -- you
can't share a line on multiple axes
