Pie charts are used to show classes or groups of data in proportion to the whole data set. The entire pie represents all the data, while each slice represents a different class or group within the whole.
For the pie chart, the following statistics are calculated:
|Mean||the average of all the data points in the series.|
|Maximum||the maximum value (biggest slice) in the series.|
|Minimum||the minimum value (smallest slice) in the series.|
|Sample Size||the number of values (slices) in the series.|
|Range||the maximum value minus the minimum value.|
|Standard Deviation||Indicates how widely data is spread around the mean.|
