I figured now that this was the bottom zero, hence I used other value instead. But here we are - there is a conceptual problem with stacked bar plots in the log scale - the stacked areas lose their proportions and are no longer illustrative.

I am having a trouble with making a bar plot with log scale enabled.
When setting simply log=True in the bar () command, all bars have junk
values of kind 1E-100. When using semilogy () on the other hand, not
all stacked bar elements get drawn, plus what is being drawn starts
"in the air" above the zero level (attached two eps files).
I must be doing the wrong thing, I suppose.
Are you specifying the "bottom" keyword argument?
