How are stem and leaf plots similar to histograms?

Stem and leaf plot is a way of displaying data, where the data value is split in the form of a stem (shown in a vertical column) and leaf shown against the stem in form of a horizontal row, to the right of the stem. It is very useful in determining the mean , median and mode of the data.

Histogram, on the other hand, is a graphical representation of uni-variate data in the form of rectangles of equal width. The width represents the class intervals in which the data has been divided. The class intervals are marked on the horizontal axis. The height of the rectangles represents the frequency of data in that particular interval.
