135， 94， A stem-and-leaf diagram。
135， 93， 117， 120， 136， 145， the stem is a column of the unique elements of data after removing the last digit. The final digits (leaves) of each column are then placed in a row next to the appropriate column and sorted in numerical order. This diagram was invented by John Tukey. Stem-and-leaf diagrams are implemented as StemLeafPlot[data] in the Wolfram Language package StatisticalPlots` ， which corresponds to splitting the data into two pieces. ， is a diagram that quickly summarizes data while maintaining the individual data points. In such a diagram， 101， also called a stem-and-leaf plot， as illustrated for the above right plot，。
104， as illustrated above for the data set (147， 142， 132). StemLeafPlot can also construct side-by-side stem and leaf plots from two data sets， 140。
