i am plotting two distinct lines, one of the format '-o' the other of the
format '-s' -- i.e. one line with circular markers the other with a square
marker. when i add a legend to the figure, it gives a legend that looks like
o---o label of circular marker line
s---s label of square marker line
however, in these types of plots, it's standard for the line in the legend
to only have *one* marker. meaning the legend should look like this:
--o-- label of circular marker line
--s-- label of square marker line
is there a way to get this modified legend appearance?
second question: how can i make the legend altogether smaller? or at least
make the label text font smaller?
