Thank you for the suggestion, but I couldn't see a difference with
antialiased either True or False. The lines between contour levels remain.
I tried a different colormap (spectral) but it had the same effect. I tried
more color levels (256) but the effect got worse.
I can't find any example
Ryan,
I have noticed the same issue with contourf. It seems to be a thin gap
between neighboring polygons showing through. You can turn on a thin
contour line of the same color to cover the gap:
for c in pylab.contourf( x, y, z ).collections:
c.set_linewidth( 0.1 )
Not ideal, but it

Eric,
Here's a pcolor plot of the same data:
contour_plot = pyplot.pcolor(x_grid,y_grid,z_grid_masked)

For contourf I'm using:
contour_plot =
pyplot.contourf(x_grid,y_grid,z_grid_masked,contour_levels,origin='upper',\
extent=extent,cmap=pyplot.cm.jet)

It looks to me like this is more suitable for showing your data than
contourf would be.
For contourf I'm using:

Hello,
In my filled contour plot: http://imgur.com/vXoCL.png
There are faint lines between the contour levels. I think they are yellow
since they disappear in the yellow parts of the graph and are most obvious
in the red areas. Is there any way to get rid of these lines? The number of
