Hi mpl users,

I get some strange results when I make a quiver plot of a masked

array. This script:

from numpy.ma import zeros, masked_values

from pylab import quiver, savefig

a = masked_values(zeros((5,5)), 0)

quiver(a,a)

savefig('test.png')

gives me a plot which has 25 horizontal arrows (although they look

strange). It should give me a plot without any arrows. Is this a bug

in matplotlib (I am using 0.98.3)?

Best regards,

Jesper

Yes, it was fixed in svn.
