`pie` is a prefab for producing pie graphs.

## Parameters

Prefab parameter name | Data type | Default | Description | Examples (ignore line wrapping)
Standard parameters |  |  | Some of the standard prefab parameters may be used. You must specify data (the name of the input data file). The only other standard parameters available with this prefab are those related to getting the plot data and legends (except for name). Note that the legend parameter is used differently with this prefab, than with others (see below).
values | data field | must be specified | Identifies the data field that will hold numeric values for the pie slices. Pie slices will be displayed as proportions of the sum of all values, unless the total parameter is used. | `values=2 values=pmb`

labelfmtstring

string

A format string that controls pie slice labels, and allows content to come from one or more data fields. Text may also contain the characters `\n` to symbolize line breaks, and the special symbol @PCT which will evaluate to the percentage of the current slice. Version 2.30+.. supersedes the `labels` parameter described below.

`labelfmtstring=@1`
`"labelfmtstring= @3\n(@PCT)"`
(label will be the 3rd data field, and below, the percentage in parentheses)

labels | data field |  | Identifies the data field that will hold labels for the pie slices. | `labels=1 labels=desc`
colorfld | data field |  | Identifies the data field that will hold colors for the pie slices. | `labels=1 labels=desc`
legend | `yes` or x y |  | If specified, slices will be labelled using a legend, instead of the default behavior of showing labels near the slices. Slices must have different colors for this to make sense. Legend labels come from the labels data field. (This description overrides the description on the standard parameters page.) | `legend=yes "legend= 0.5 1.2"`
lbldet | textdetails |  | Specify text appearance details for the pie slice labels. | `"lbldet= size=8"`
