You have to make sure your yaxis limits are strictly

No that won't quite do it, sorry for the noise. The problem is that
the histogram bottom of the rectangle is zero by default, and
transforming those vertices are causing the problem. You need to use
the "bottom" kwarg to set the bottom of the bars to be positive, eg
hist(rand(100), 20, bottom=1e-3)

Oops, I replied to your previous message before seeing this one.
Still, the larger question remains: maybe we should do something to make it easier for users to understand what is going on when the transform chokes on log(0). Changing numbers <=0 to a small positive number and issuing a warning would accomplish this, and I don't see much disadvantage.
