Hi there, I think this functionality already exists exactly as you describe. ax.plot appends new lines to ax.lines, ax.scatter appends new collection to ax.collections (via the ax.add_collection method). try this, and you'll see the cyan line is removed: plt.plot([1,2,3],'r') plt.plot([1,2,1],'c') ax = plt.gca() del(ax.lines[-1]) plt.draw() -- Paul Ivanov 314 address only used for lists, off-list direct email at: http://pirsquared.org | GPG/PGP key id: 0x0F3E28F7
