This appears to be an aliasing "screen door" effect. I can reproduce it somewhat on mac firefox while reshaping the window, but when I let go of the edge of the window, it re-renders and the problem goes away. I do not see this effect on mac chrome. @matthew-blackman or @catherinecarter can you help investigate the cause of this?

@samreid and I investigated this and found that the issue was that the major grid line spacing was not a multiple of the minor grid line spacing for a bin width of 2. We fixed the issue by changing the major grid line spacing from 5 to 10, which also made the histogram consistent with the lines on the field. Nice work! Closing.
