When there are more than 10 (unlabeled) lines in a graph, they appear in the combobox as
_line0
_line1
_line10
_line11
...
_line2
_line3
etc.
"Natural" integer sorting (https://pypi.python.org/pypi/natsort) would be, well, more natural here. Or one could hack the "default" labels ("_lineX") to return a str subclass with a custom comparator, so that other labels are not affected.
