This is a "feature" of scatter that has annoyed many people. I'll see
if I can come up with something better.
To plot a dot, use
plot(x, y, '.') # draws a *very small* circle
plot(x, y, ',') # draws a pixel
To plot circles (not ellipses) on axes with different scales, use
plot(x, y, 'o') # draws a circle
In the latter case you can set the marker size attribute in points
plot(x, y, 'o', markersize=6) # draws a circle with a 6 point radius
As long as you want the markers to be the same size and color, you
should use plot. If you need either the size or color to vary, you
need scatter. In which case I need to get the transform issue fixed
up sooner rather than later.
