On demo for histogram, try right clicking and selecting y axis, then clicking log scale, the bounding "Theoretical" line remains (showing there should be something there), but the histogram itself disappears. Manually setting ImPlotAxisFlags_LogScale also does the same thing, so it isn't just some demo bug. Log scale seems to work fine for histograms on the X axis.

Thanks. The issue is that the bottom of each bar is referenced to 0 on the y axis which can't be displayed on log scale. The result is that the entire bar is not drawn. We may need to convert 0s to a really small value to make this work. I'll have to think on it.
