I'm not quite sure what /should/ happen when you set the `facecolor` to
'none' and the `edgecolor` to 'face'. I'm surprised anything shows up at
the axes at all. But if you remove the `edgecolor` kwarg things look better:

import matplotlib.pyplot as plt
fig = plt.figure()
plot = fig.add_subplot(111)
plot.scatter([1, 2, 3], [4, 5, 6], c = [0.2, 0.4, 0.6], label = 'one',
     cmap = 'jet', marker = 'o', edgecolor = 'face')

plot.scatter([1, 2, 3], [7, 6, 5], c = [0.2, 0.4, 0.6], label = 'two',
              cmap = 'jet', marker = 'o', facecolor='none')
plot.legend()
plt.show()
