This bug is actually due to a different recent change, in which I fixed the half-cut-off first and last bars in the bar-like charts. The case I missed was when there is only one row of data, in which case it doesn't know how wide the bars should be. Zero rows of data might cause a related problem, but my fix for this will catch both of those cases. I'll see about patching this change in the new release.
