Interface IChartModifier

public interface IChartModifier

The interface for modifying the attributes of a chart embedded in a report. The class (implementing this interface) is then assigned to the chart using the method setChartModifier in ReportChartObject.

A typical use of this interface involves:

 
    QbReport report = ...;
    ReportChartObject chartObject = new ReportChartObject();
    chartObject.setText(chartLocation0);
    // Change the chart HERE using class created implementing IChartModifier
    chartObject.setChartModifier(new ChartModifier());
    ...
    // definition of ChartModifier somewhere else in code
    // Create class to modify existing template chart.  In this case, 
    // turn background color to pink
    public class ChartModifier implements IChartModifier {
       public ChartModifier() {};
       public IChart modifyChart(Object chartInfo) {
          ChartObject chart = new ChartObject(chartInfo);  // Get actual ChartObject
          chart.gethCanvas().setBackgroundColor(Color.pink);
          return chart;
       }
    }
