Histograms

A histogram is quite similar to Bar charts in that they both have rectangular bars. However, with Histograms the bars can be of different widths, there are no spaces between each (as there is a standard scale on the horizontal axis i.e 1, 2 etc) and the bars must be vertical. The height of each bar is equal to the frequency which it represents.

Example

The table below lists the number of goals Chelsea scored in the first 6 matches of the 2009/2010 Barclays English Premier League Season.

Match # 1 2 3 4 5 6
