Get Incrementer from Chart Customizer

[thangalin]

Hi,

/**
 * Draws a (smooth) Bezier line between consecutive data points on a chart.
 * This is especially useful for Time Series plots.
 */
public class BezierLineCustomizer
  extends JRAbstractChartCustomizer {
 
  public BezierLineCustomizer() {
  }

  /**
   * Initializes the chart customizer.
   * @param chartFiller Ignored.
   * @param chart Contains the
   */
  @Override
  public void init( JRBaseFiller chartFiller, JRFillChart chart ) {
    super.init( chartFiller, chart );

    JRTimeSeriesDataset dataset = (JRTimeSeriesDataset)chart.getDataset();
    dataset.setTimePeriod( org.jfree.data.time.Day.class );

    JRFillVariable trendAverage = chartFiller.getVariable( RunningAverageIncrementer.IREPORT_VARIABLE );
    JRIncrementer incrementer = trendAverage.getIncrementer();
   
    if( incrementer instanceof RunningAverageIncrementer ) {
      ((RunningAverageIncrementer)incrementer).setSetSize( 30 );
    }
  } // ... etc. ...

 The bold line in the code above does not compile.

Is there another way to get the JRFillVariable instance from a subclass of JRAbstractChartCustomizer?

Thanks!

Another way to get the incrementer:

  private JRIncrementer getIncrementer( JRBaseFiller chartFiller ) {
    JRVariable[] variables = chartFiller.getMainDataset().getVariables();
    JRIncrementer result = null;
   
    for( JRVariable var : variables ) {
      if( var instanceof JRFillVariable ) {
        result = ((JRFillVariable)var).getIncrementer();

        break;
      }
    }
   
    return result;
  }
