unfilled scatter points

hi,

is it possible to draw unfilled scatter points?
i want to use an unfilled 'o' marker with a dashed border to
represent the 'expected' data, as opposed to the observed data.
i can make the border dashed but haven't figured out how to
make the marker not filled.

any idea?
thanks!

Yes, try the following

import numpy as np
import matplotlib.pyplot as plt
x = np.random.rand(10)
y = np.random.rand(10)
plt.scatter(x, y, facecolor='none')
plt.show()

Also take a look at
http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot.scatter
