==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.
