notice fillto= doesn't help:

julia> barplot([1,2,3,1,2,3], [1,2,3,1,2,3], stack=[1,1,1,2,2,2], color=[1,1,1,2,2,2], gap=0, fillto=eps(); axis=(; yscale=log))
┌ Warning: Ignore keyword fillto when keyword stack is provided

It looks like, from further testing, that it's just the first set of bars (at stack level 1) that aren't drawn - if you add more stacks, everything else seems to be drawn correctly...

Yea because the bottom bars reach zero which is impossible in log scale so it got "canceled"

Use pseudolog to avoid the infinity at zero?

that would look "weird" to HEP community, basically since we never display zero, we should fill to eps()

It was suggest that maybe we can bypass this by shifting data and translate!(), unfortunately it doesn't work, in fact, shifting data doesn't help:

barplot([1,2,3,1,2,3], [1,2,3,1,2,3] .+ 2, stack=[1,1,1,2,2,2], color=[1,1,1,2,2,2], gap=0; axis=(; yscale=log)

Isn't the solution here just to implement fillto for stacked barplots? Or am I reading this wrong?
