over a period of time.

Pie Chart

A pie chart is used to plot the data for
a single data series. Each data point is
represented by one slice of the circular pie

to the value it represents. So, all the data
points taken together make a complete
circular pie chart. It is useful when you
want to focus on a signifi cant element.
