Our group just got JMP v15.1 installed on our systems today, so it was my first chance to try it out.
At risk of being gratuitous, I have to say the new histograms in the column headers is probably the best and most surprisingly-useful-and-well-implemented feature I've seen in a piece of software in a very long time. I was delighted -- and even giddy -- when I realized I could click on the bars in the histograms to select the corresponding rows and have them highlight in the other column-header histograms. I felt like I instantly had a sense for what was in the file, and could quickly gauge what was driving some of the key factors.
It's frankly brilliant. Kudos to whoever had the idea, and even more to those who figured out how to implement it so cleanly. Bravo!
