Histograms typicaly show counts of data that fall into a predefined bin or class.
An example would be ...
X axis
Grade range from 50 to 100 percent in "class" increments of 5 percent,... you set the "bin" or "class" size as you see fit.
Y axes
The counts of students who's grade(s) fall within those classes
those counts will always form a bell shaped curve.
and that is what makes a histogram different from just a bar chart.
Note "class" or bin refers to statistical lingo ... just so happens that this is a classroom example.
