It also supports categorical and text as input. Stem-and-leaf plot – a graphical representation used to analyze and compare groups or clusters of numerical data by separating the digits in numerical values based on place value. Review data representations that use the number line and outlines the data types that work best with each of the representations. Moreover, some are largely consequences of using printed text to show stem-and-leaf displays as, in essence, tables rather than graphs. one-digit number (such as 9) using a stem-and-leaf plot, use a stem of 0 and a leaf of 9.
