According to the 0.3.7 documentation at http://julia-demo.readthedocs.org/en/stable/stdlib/math.html?highlight=hist2d!#Base.hist2d!, the function hist2d! is included as a standard function.
However, when I type hist2d! into the REPL, I just get an error message: julia> hist2d! ERROR: hist2d! not defined But when I type Base.hist2d!, it does appear to recognize it. Does this mean it wasn't properly exported?
