title: Reporting Trend Line
body: <p>How would you create a line in JasperReports that follows the trend for the data, in addition to showing the data points? Here are before and after shots:</p>

  <p>The Time Series report does not appear to have any such option to draw the orange line. (The orange line should be smooth, and thinner, but that's the general idea.)</p>
  
  <p>Any ideas how to craft such a report with iReport 3.7.1?</p>
