Thread: [Matplotlib-users] removing a line with its label from an axes

Hello,
I know how to remove a line from an axes. But a I also want to remove the
label of the line from the legend of the axes.
In the sample code you can see two labels in the legend, while there is only
one line in the axes left.
import numpy as N
from matplotlib.pyplot import *
x = N.linspace(-10,10,201)
ax = figure().add_subplot(111)
ax.plot(x, x**2, label="$x^2$")
ax.plot(x, x**3, label="$x^3$")
ax.legend()
ax.lines[0].remove()
show()
Regards
Magnus

Try calling legend() again once you've changed the lines; in ipython - 
pylab, this
x = linspace(-10, 10, 101)
sub = subplot(111)
plot(x, x**2, label="x^2")
plot(x, x**3, label="x^3")
legend() #Two lines, two legend entries
sub.lines[0].remove() #One line, two legend entries
sub.get_lines()
legend() #One line, one legend entry
works for me.
