# display-zeros attribute

Type: | boolean
Inherited: | no
Used By: | piegraph
Default: | false

This attribute determines whether a slice in a Piegraph that has a value of zero is displayed or not. By "displayed" we only mean is included in the key, as obviously a zero-width slice is not going to have any substance in the graph itself.

The first PieGraph below will have three items in the key, the second only two.

    <piegraph width="100" height="100" display-zeros="true">
      <gdata name="apples" value="20"/>
      <gdata name="oranges" value="30"/>
      <gdata name="kumquats" value="0"/>
    </piegraph>

    <piegraph width="100" height="100">
      <gdata name="apples" value="20"/>
      <gdata name="oranges" value="30"/>
      <gdata name="kumquats" value="0"/>
    </piegraph>
