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):
  File "./novi.py", line 604, in ?
    main()
  File "./novi.py", line 576, in main
    MaxP =3D plot_Haps(canvas, map, Haps)
  File "./novi.py", line 367, in plot_Haps

  File "./novi.py", line 389, in plot_hap
    line.set_visible(Plot.False)
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

Jean-Baptiste
