 [Matplotlib-users] invisilbe line From: Jean-Baptiste Cazier - 2004-03-12 12:59:22 ```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 ?

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() ```

 [Matplotlib-users] multiple plots fail in TkAgg interactive From: matthew arnison - 2004-03-16 07:01:52 ```I can't seem to get multiple plots to draw on the same figure under TkAgg.

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 matthew> Cheers and thanks for matplotlib, Matthew.

 [Matplotlib-users] eps bounding box buggy in 0.52 From: matthew arnison - 2004-03-29 08:02:19 ```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. ```
