Suppose you have a data set of 4000 numbers from 18 to 47 (4000 student ages, for example). At first you have 4 stems: 1, 2, 3 and 4. If you split the stems, you will have 8 classes. If each class receives the same number of leafs, which is very unlikely, each class wil have 500 digits. That is, you will have to write 500 leafs in each stem. The sequence of digits will be very long and graphically useless
