Is there a memory-efficient workaround in my dummy example (instead of
increasing N)?
Thanks,

N is too large, the plot becomes very slow, and a lot of memory
is used; I think because an array is probably built with this size, although
in theory there is no need to construct such a complete array.
Is there an easy workaround, or have I to study and modify the matplotlib code
myself?

Hi everybody,
I try to move an instance of matplotlib.lines.Line2D from one subplot to
another. How to do that? I have tried the following code, but the Line2D
does not appear on the second subplot.
Thanks in advance,
Julien

Hi everybody,
I try to play with "sharex" feature. Then, I have been guided to the
class "Grouper" of module cbook:
http://matplotlib.sourceforge.net/api/cbook_api.html
So I tried the following example:
##
from matplotlib.cbook import *
g = Grouper()
g.join('a', 'b'
Hi everybody,
I want to modify a matplotlib.lines.Line2D and update the plot.
I have used Line2D._y member to modify the line. It works. But by doing
canvas.draw() (see example below), the line is not updated on the plot. To
update it, I have to do autoscale_view(). But I do not want the x and y

Hi everybody,
I want to delete a subplot from my figure. How to do that?
For example, I would like to remove the right subplot in the following
example:
from pylab import *
ion()
f = figure()
s = f.add_subplot("121")
X1 = arange( 0.0, 5.0, 0.1 )
s.plot( X1, X1**2)
s =
Hi everybody,
I would like to update a subplot position automatically. Try this example:
##
from pylab import *
f = figure()
s1 = f.add_subplot( '111' )
s1.plot( [5,7], [6,9], 'r' )
s2 = f.add_subplot( '212' )
s2.plot( [5,7], [4,9], 'b' )
show()

The problem is

Impressive!
Thanks a lot, now it works perfectly!

Hi everybody,
I encounter a strange behavior of TKAgg backend with Matplotlib 0.98.5 and
SVN versions, when panning: the grid lines do not always match the ticks on
the axes:

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_subp

Ok, del only removes a name from the local namespace.
I have found an old answer of John, below. It seems that a better solution
is to use the remove method of a line instance:

Hi everybody,
I have a question about the behavior of "del()" Python built-in.
In the following example, when I use del() on the copy of a line, it does
not delete it, whereas with the original line, it works. Why? I do not
understand, because the id is the same for the copy and the original:

Hi everybody,
In my own application, I want to specialize matplotlib.lines.Line2D to be
able to deal with units.
Concerning this class, is there a direct means to plot instances?
For example, if I do:
>>> a=matplotlib.lines.Line2D([5,6],[7,8],color='m')
To plot it, I have not found another way

Hi everybody,
Below you will find a small script that plots the graph of a simple function.
This code is aimed to be embedded in a GUI application.
I set the subplot dimension with the b.set_position([]) command. The floats
that are given to set_position() are percents relative to the Figure
