Stem-and-Leaf plots are another form of histograms (one may consider
these plots as the alphanumeric version of a histogram). This display is
calculated by using the integer portion of the data as the "stem" and the
digit after the decimal point as the "leaf". Each stem is printed in one
line, and all leaves of a stem (that means all values which have the same
integer values) are printed in ascending order in the line of the corresponding
stem. Normally, only the first digit after the decimal place is used to
build up the stem-and-leaf display.
Note that the data may have to be range scaled before calculating the stem-and-leaf plot.
