Removed titles, adjusted sizes of legends, and made overlaid histograms square. Still going to work on the xaxis for the second overlaid histogram- the units might need adjusting to change the size of the tick labels.
This is looking nice. I'll leave it open while you are tweaking the exposure time histograms. You could convert to using minutes instead of seconds to make the axis labels fit better.
