Use the <dvt:sparkItem> tag to represent and provide data for a bar or marker in an ADF spark chart. The <dvt:sparkItem> tag accepts EL Expressions for its values, and is particularly useful when stamped within an af:iterator or af:forEach tag.
The <dvt:sparkItem> tag is typically a child of the <dvt:sparkChart> tag.
