h2. Pie Chart
{anchor:piechart}
The pie chart plots a single value per series in a pie shape.
h3. Dataset Guidelines
The pie chart dataset typically contains two columns. The first column's values are the series names, and the second column contains the data values. If the dataset has multiple rows for each series, the row values will be aggregated, so that each series appears only once in the pie.
The pie chart also supports the *by-row* property, meaning that the dataset can be row based. In this case, you may have multiple numeric columns in your dataset, whose headers will become the series names, and the data values would aggregate across the rows to formulate the series value.
here is a sample pie dataset:
|| DEPARTMENT || ACTUALS ||
| Sales | 11,168,773 |
| Executive Management | 6,299,022 |
| Finance | 12,224,220 |
| Human Resource | 13,075,463 |
| Marketing & Communication | 13,910,753 |
| Product Development | 10,644,102 |
| Professional Services | 76,317,649 |
h3. Required Properties
The only property a pie chart requires is the appropriate chart-type.
