S=E6l ! Is there a way to "turn-off" lines without removing the data ? My goal is to hide some lines in a plot wihtout losing the data so I can sh= ow it again later. I can do=20 # Hide the line x=3Dline.get_xdata() y=3Dline.get_ydata() line.set_data([],[]) # Reset the line line.set_data(x,y) But I would prefer I more elegant way like line.hide() line.show() Would it be possible to get something like that ?

This can be done very easily (for any artist) with a minor
modification of artist.py. The base class forewards all drawing to
the derived classes so no other changes are required. Just replace
artist.py with the attached file below and then you can do:
from matplotlib.matlab import *
x =3D arange(0.0, 1.0, 0.05)
l1, l2 =3D plot(x, sin(2*pi*x), x, sin(4*pi*x))
l1.set_visible(False)
show()

S=E6l !
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):

line.set_visible(Plot.False)

And this happens even if I redo the full installation of matplotlib 0.51:

This is my routine:

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

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

I can't seem to get multiple plots to draw on the same figure under TkAgg.
In the below example, the cos() doesn't show up, and the tan produces an
error. This seems to be repeatable for arbitrary cases of trying to plot
2 or 3 lines together on the one plot.
Cheers and thanks for matplotlib,
Matthew.

Found and fixed. This crept into the functions that process plot
arguments when I added matplotlibrc support there. In axes.py, search
for def _plot_1_arg and replace the first part of it with
def _plot_1_arg(self, y, **kwargs):
if self.count==0:
color = self.firstColor
else:
color = self.colors[int(self.count % self.Ncolors)]
^^^ this is the critical part

Thanks for the bug report!

Hi Just a quick note that the EPS bounding box still seems to be buggy in matplotlib 0.52. If I save an EPS using the save button on a GTK figure window, the right hand side gets slightly clipped when printed. If I do the same from a TkAgg window, most of the plot gets clipped. Cheers, Matthew. |
