I'm afraid the scatter plot does not allow afterward adjustment with size
currently (by using setp).
Probably you should redraw the scatter points with different sizes. like
for x,y,z in zip(xlist,ylist,sizelist):
m.scatter(x,y,s=z)
if you question is to change the real 2km or 1.5km to the size on the map,
sorry I don't know as I never did this. Probably you need consider
projection.
