You have two options -- the axes stores the lines in a plain-ol-list,
and you can manipulate that list like any python list
If you know the line number, ie, the i-th line you've added to the
list
del ax.lines[linenumber]
if you don't know the line number, but have an instance of the line
l, = ax.plot(x, y)
ax.lines.remove(l)
After you've removed the lines, you'll have to force a figure redraw
In pylab, you can simply call
draw()
or using the API, use the figure canvas method
canvas.draw()
The containment relationship is Canvas holds a Figure holds an Axes,
but each child has a pointer to its parent, so if you have access to
an Axes instance
ax.figure.canvas.draw()
