The Pie chart option draws all values for a single row (or column) as fractions of a whole. The fractions are calculated as a percentage of the sum total of all values for the row (or column). The whole is represented as a circle.
When the 2D graph is stacked or side-by-side, multiple pies are displayed. For example, there may be a separate pie for each row. Within a single pie, each fraction represents the values for a particular column.
A single pie can contain a maximum of 32 sections. Negative values are not possible for this graph type.
Select Options® 2D options to call up the 2D Options dialog window and choose the graph type.
