Error when plotting Histogram about metricsgraphics

Encountered the same problem.

I could not replicate. That same sequence of commands works fine for me. Here's my session info (note that "local v 0.8.0" has virtually no differences besides documentation and moving some Depends to Imports, so that's probably not the issue):
