[Matplotlib-users] empty scatter

[Paul Hobson]

Vincent,

I think you want to use `plot` with no line, like so:


from matplotlib import pyplot
fig, ax = pyplot.subplots()
ax.plot([1, 2, 3], [3, 6, 1],
        linestyle='none', marker='o',
        markeredgecolor='k',
        markerfacecoloir='none')
