[Matplotlib-users] numpy masked array plot - isolated single unmasked value is hidden

[Gregorio B. <gre...@gm...>]

Hi,

The following example demonstrates the problem, value 5 could not be
seen w/o marker:

data = np.arange(10)
mask = [0,0,0,1,1,0,1,0,0,0]
x = np.ma.masked_array(data, mask)
plot(x)
plot(x, '+')

In my datasets, isolated unmasked values are rare, but placing a
marker to spot them makes the whole graph cluttered. I do realize that
at least 2 valid points are needed for a line segment, but still, is
there any way to visualize these isolated unmasked values w/o a
marker?

Thanks,
Gregorio
