add_line method sets label to something like "_line1" if not set.
def add_line(self, line):
if not line.get_label():
add_collection sets label to "collection1" if not set.
def add_collection(self, collection, autolim=True):
label = collection.get_label()
if not label:
add_patch does nothing.
Can someone enlighten me why add_line and add_collection method sets the label?
Actually, my issue here is that collections without empty label show
up in the legend as "collection1" etc., instead of being ignored.
