I am making a scatter plot and want the legend to display the symbols.
This functionality doesn't seem to exist, so I have followed the
workaround outlined here:
Are there any plans to make the symbols which are available in plot()
the same as those available for scatter()? If not, can we at least
get the diamond symbol the same? I want to pass the same symbol to
plot() and scatter() and get the same symbol---as it is, I must use
'd' in scatter and 'D' in plot.
Also, how are the markersizes scaled? For example, in scatter(), I am
using s=30...but if I do plot(...,markersize=30), then the markers are
not the same size as the markers from the scatter plot. I can go back
and forth until the scale is right, but is there a better way?

I think this is worth fixing -- could you file a bug on the
sourceforge site and note any symbols you are aware of that don't
agree between plot and scatter.

Note sure if this is a bug or a feature, but it is a consequence of
emulating the matlab approach. In scatter, the size often is used to
convey information, and the size parameter give thes area of the
circle that circumscribes the marker. In plot, he marker size is not
generally intended to convey information, only that something happened
here, and the size choice is usually one of aesthetics. In any case,
in plot the size is radius of the circle, the side of the square or
diamond. For most markers, you should be able to square the
markersize to get approximate correspondence between plot and scatter.
