Very nice. The horizontal bar graphs were always one of the most awkward parts of the initial PTS implementations.
I didn't worry about the graphs because getting the foundation in place was the biggest and most important task and graphs could always be changed later, but it's great to see the whole suite maturing to the point where you can start to put time on polishing the output.
The new graphs are a great improvement and allow more information to be usefully presented. I'm sure the next request will be to somehow show the standard error information graphically (some kind of stacked bar graph I guess) but IMO getting this level of improvement out is more important.
Thanks for all the great work you have been doing on PTS.
