Histogram – A pictorial representation of data shown in equal intervals. There is no space between the intervals because there shouldn’t be any gaps in the intervals.

A histogram is like a bar chart but the columns are joining

A histogram looks like a historical FORT diagram.


Example 1

An example of a histogram with its columns joining, from a progression of numbers on its x axis

This histogram depicts the maths test scores of students. See how the intervals on the `x` axis go up in set intervals.


Example 2

Another example of a histogram showing one column is showing 2 sets of data, how many and for how long in this case

The bar heights on histograms will vary depending on the data but all the bars will touch the adjacent bars.
