Please go to the JMP Wish List, and specify your opinion to change it back to the old structure.
And also, you can go to
View==>Customize==>Menus and Toolbars
and then go down to the place where the Variability/Attribute Chart is located, copy the entry, and the go back to the location on the Analyze menu, and insert it into the Analyze main menu. And you will be right back to where you were in JMP 13
