Does this mean you have the entire grid of points?
In any case, you can get an array of your points
as np.array([(x,y,z) for (x,y),z in d.iteritems()])

To get a field plot with null clines,
I'm using the approach John illustrated here:

Is this the recommended approach these days?
Thanks,

Can you explain this:
norm = colors.Normalize(vmin = -1, vmax = 1)
I take it that this scales the range for the
color bar, which is what 'luminance' must
refer to in the docs? In which case, can
we just set vmin and vmax as i

OK, it's obvious one you point it out.
Sorry for the typo in the example.
Now suppose I want a colorbar labelled at
Using contourf in version 0.99.1,
I'm seeing an unwanted white strip to
the top and right, adjacent to the axes.
(In fact, the strip looks just wide
enough to underlay the ticks.)

PS Simple example:
x = np.linspace(-5, 5, 100)
X, Y = np.meshgrid(x, x)
Z = np.sin(x*y[:,None])
fig = plt
1. Sorry if I miss this in the docs, but what are
the default values of rstride and cstride?
It seems these automagically limit the amount
of data used by the surface plot.
2. Also, what is the right way to set alpha for
the surface? If I use an alpha keyword for
plot_surface, I cannot seem to pu
