"Chronology," by Melissa J. Churchill and Scott G. Ortman

Figure 1. Stem-and-leaf plot of all tree-ring dates for Woods Canyon Pueblo. Each numeric digit in the bars of the histogram represents the final digit of one tree-ring date. For example, in the third bar from the bottom, there are two dates in the A.D. 1250s: 1251 and 1257. The latter is a cutting date.
