<td colspan=2>Some of the <a href="prefab_stdparms.html">standard prefab parameters</a> may be used.
You <font color=D00000>must specify</font> <b>data</b> (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 <b>name</b>). Note that the <b>legend</b> parameter is used
differently with this prefab, than with others (see below). </td>

Pie slices will be displayed as proportions of the sum of all values, unless the <b>total</b> parameter is used.</td>

<tr bgcolor=FFFFFF>
<td><b>labelfmtstring</td>
<td>string</td>
<td> </td>
<td>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 <tt>\n</tt> to symbolize line breaks, and
the special symbol <b>@PCT</b> which will evaluate to the percentage of the current slice.
Version 2.30+.. supersedes the <tt>labels</tt> parameter described below.

<td>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 <b>labels</b> data field.
