You may try to get the line to remove with
self.gex, = self.axes.plot(ex[:,0],ex[:,1],'b', lw=2,label = mypathex)
in openex (note the comma)
To remove the line, put
self.gex.remove()
in delex function.
An alternative is
self.axes.get_lines()[-1].remove()
so that you don't need self.gex for this.
Now, you need a function to interactively select the line. I don't have
a solution for that, but I'm interested too!
