Hi all, I'm a complete beginner with Julia, so perhaps I'm missing something obvious, but I'm not able to produce histograms with Gadfly. I thought at first I was using it wrong but even the example from the docs <http://dcjones.github.io/Gadfly.jl/geom_histogram.html> doesn't work for me. Here's a notebook that shows what I get (same thing with writing the plot to a PNG file): http://nbviewer.ipython.org/gist/kleinschmidt/46998cf74fd8f066485e
Any ideas? Thanks, Dave
