==Summarizing Summarising Report Data==__NOEDITSECTION__In addition to displaying report details in an iReport template, the iReport Designer allows you create creating summaries or calculations of data returned in the report. These can take the form of totals, sums, and counts (stored in Variablesvariables), or more complicated data summaries such as Crosstabs crosstabs or Chartscharts. Because summarizing data necessarily depends on multiple records, data summaries must exist in bands ''after'' the Detail band such as the Summary band, Footer badband, or Group Footer bands.

==Crosstabs==__NOEDITSECTION__In addition to summary variables, iReport provides the capability to build crosstab tables that display data in a grid for easy analysis and summary. Crosstabs allow you to choose data rows, columns, and the variable to be measured and then automatically produce a grid of results for display in a chart. As with other summary variables Crosstabs are generally used in the '''Summary Band''' in a report.  To create a Crosstab:# In the '''Palette''' pane, drag a '''Crosstab''' item to the Summary Band of the report.# The Crosstab wizard displays#: [[Image:IReport Crosstab1.png|center|500px|''Crosstab wizard'']]<div align="center">''Crosstab wizard''</div># Select the '''Field''' to use in the '''Row''' of the Crosstab grid.#: [[Image:IReport Crosstab2.png|center|500px|''Crosstab wizard'']]<div align="center">''Crosstab wizard''</div># Select the '''Field''' to use in the '''Column''' of the Crosstab grid.#: [[Image:IReport Crosstab3.png|center|500px|''Crosstab wizard'']]<div align="center">''Crosstab wizard''</div># Select the '''Field''' or '''Variable''' to use to represent the data in the grid.
