plot always return *a list* of lines. So you need to do
 lines = canvas.figure.axes[0].plot(Xrange, Yrange, symbol)
 lines[0].set_visible(Plot.False) # get the first element of the list

Thanks for the change of the artist class. It should do exaclty what I want
I modified artist accordingly (no more 'transform' defined ?
I can run you example witout problem.
But If I implement it in my program which is embedded within gtk with the o=
bject_picker, it does not work:
If I try to set_visible on lines I just define with plot I get an error mes=
sage
Traceback (most recent call last):

AttributeError: 'list' object has no attribute 'set_visible'
And this happens even if I redo the full installation of matplotlib 0.51:

This is my routine:
def plot_hap(canvas, map, h , symbol, size=3DNone):
 """ plot the specific haplotype """
 lh=3Dlen(h.haplist)
 Xrange=3D[map[m] for m in [y for x,y in h.haplist]]
 Yrange=3D[-math.log10(h.pval) for i in range(lh)]
 line=3Dcanvas.figure.axes[0].plot(Xrange, Yrange, symbol)
 line.set_visible(Plot.False)
 return line
Any idea ?
Thanks
