Growth of Com Stalk A graph titled Growth of Corn Stalk has time (weeks) on the x-axis, and height (inches) on the y-axis. A line goes through (0, 0) and (4, 25).

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
