Thread: Re: [Matplotlib-users] removing lines from plot

redlines.set_visible(False)

it is also possible to delete the line from ax.lines.
Ex: del ax.lines[-1] deletes the last line.

you need to perform a redraw for the change to be visible on the plot.

Hi
I've added some lines with
ax.add_line(yellowlines)
ax.add_line(redlines)

how can I remove the lines without completely redrawing everything?

There are more "correct" ways to do this.  For example, each artist object
comes with a "remove" method:

http://matplotlib.sourceforge.net/api/artist_api.html?highlight=remove#matplotlib.artist.Artist.remove

So, if you save the lines that you create from the call to plot, you can
subsequently remove them at your leisure.
