Hello,
I want to create a matplotlib plot for 2 different lines, however I need the lines to have different markers.
i.e. use 'x' as marker for line 1 and '^' as marker for line 2.
I tried to use itertools.next() as I saw in some online suggestions but no luck, plot still appears with 'x' as marker for both lines. Can someone help?
My MWE code and the resulted plot below:
