How do you change plot symbols and symbol size?
This is changed by changing the
marker attribute in the
object. If you have a graphics method
my_gm.marker = 4
sets the plot symbol to a circle. You can find a list of symbols here.
Symbol size is set by the
markersize attribute in the
graphics method object:
my_gm.markersize = 5
The units for
markersize seem arbitrary, like the values
for text height.
Through trial-and-error, it appears that 1
markersize unit equals 2 text height units,
i.e. a plot symbol of
markersize = 20 is around the same size as
text of height = 40.
