Preparing your data is usually more than 80% of the job… But in this simpler case, you don’t have to worry about data … For example, to plot x matplotlib.pyplot.scatter(x, y, s=20, c=u'b', marker=u'o', cmap=None, norm=None, vmin=None, vmax=None, alpha=None, linewidths=None, verts=None, hold=None, **kwargs).
