I would like to make a histogram with logarithmic values on the y-axis (the histogram density). cgHistoplot will accept /YLOG as a keyword and plots the values, but the top axis is always misplaced; it appears in the bottom 25% of the plot. Any tips as to how this can be fixed?

My apologies for not checking this for so long, David. The fix on my computer looks excellent (and it appears that you checked it into the latest CG version). Thanks for doing this.
