  • Method Details

    • getSeriesExpression

      JRExpression getSeriesExpression()
      Returns:
      the expression of the series name. The value of this expression can be any java.lang.Comparable object.
      Note that this expression may return different values with each iteration, which in turn will result in the dataset having multiple category series, even though a single <categorySeries> tag was used inside <categoryDataset>. However, this expression usually returns a java.lang.String constant, and there are several <categorySeries> tags that introduce multiple category series in the dataset.

    • getCategoryExpression

      JRExpression getCategoryExpression()
      Returns:
      the expression of the name of the category for each value inside the series specified by the series expression. Categories are java.lang.Comparable objects (not necessarily java.lang.String objects).

    • getValueExpression

      JRExpression getValueExpression()
      Returns:
      the value expression, a java.lang.Number value for each category in the specified series.

    • getLabelExpression

      JRExpression getLabelExpression()
      Returns:
      the label expression. If present, this expression allows customization of the item labels in the chart.

    • getItemHyperlink

      JRHyperlink getItemHyperlink()
      Returns the hyperlink specification for chart items.

      The hyperlink will be evaluated for every chart item and an image map will be created for the chart.

      Returns:
      hyperlink specification for chart items
