InexactError #860

Closed ShnitzelKiller closed 5 years ago

ShnitzelKiller commented 8 years ago

When plotting a collection with exactly one data point using Geom.histogram2d or Geom.hexbin, Gadfly crashes: julia> plot(x=[0], y=[0], Geom.histogram2d)

This also happens when specifying your own bin counts.

I can reproduce this, but I'm not sure what the proper way to handle this is. How would you even set up binning when there is only one datapoint?

@shashi any idea how to handle this?
