Interface JRHighLowDataset

    • Method Detail

      • getSeriesExpression

        JRExpression getSeriesExpression()
        Returns:
        the expression of the series name. Currently only one series is supported inside a High-Low or Candlestick chart. This limitation is documented inside JFreeChart, the library used for the built-in chart support. However, this single series must be identified by a java.lang.Comparable value returned by this expression, and it must also be used as the series name in the chart's legend.
      • getDateExpression

        JRExpression getDateExpression()
        Returns:
        the expression of the date to which the current (high, low, open, close, volume) item refers.
      • getHighExpression

        JRExpression getHighExpression()
        Returns:
        a numeric expression that will be part of the data item added to the series when the dataset gets incremented.
      • getLowExpression

        JRExpression getLowExpression()
        Returns:
        a numeric expression that will be part of the data item added to the series when the dataset gets incremented.
      • getOpenExpression

        JRExpression getOpenExpression()
        Returns:
        a numeric expression that will be part of the data item added to the series when the dataset gets incremented.
      • getCloseExpression

        JRExpression getCloseExpression()
        Returns:
        a numeric expression that will be part of the data item added to the series when the dataset gets incremented.
      • getVolumeExpression

        JRExpression getVolumeExpression()
        Returns:
        a numeric expression representing the volume value to use for the current data item. It is used only for Candlestick charts.
      • getItemHyperlink

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

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

        Returns:
        hyperlink specification for chart items
