An Excel 4.0 was peak Excel. It brilliantly chose axis limits for you in scatter graphs, rather than wasting two minutes of your time every time you created one. Create new data series in the formula bar. Write your own functions and macros without consulting documentation. (I had to create my own ATAN2 (quadrant sensitive two-variable input arctangent. Ironically, when it began appearing as a standard function, it was called ATAN2!)
