Why don't you just use the code provided here: http://matplotlib.sourceforge.net/examples/api/watermark_image.html
The first thing to do when you want to plot something is maybe to look at the examples section, isn't it? It shows pretty good how to not only mark points, but also to mark points with semi-transparent circles. Please keep in mind: Plotting a set of lines and mark several points produces exactly the same image as plotting a set of lines and, above that, plot a set of circles. Maybe there are "cleaner" solutions, but to get an impression how to do things this might be enough.
