Class StackedXYAreaRenderer2

    • Field Detail

      • serialVersionUID

        private static final long serialVersionUID

      • roundXCoordinates

        private boolean roundXCoordinates
        This flag controls whether or not the x-coordinates (in Java2D space) are rounded to integers. When set to true, this can avoid the vertical striping that anti-aliasing can generate. However, the rounding may not be appropriate for output in high resolution formats (for example, vector graphics formats such as SVG and PDF).

    • Constructor Detail

      • StackedXYAreaRenderer2

        public StackedXYAreaRenderer2()
        Creates a new renderer.

        Constructs a new renderer.
        Parameters:
        labelGenerator - the tool tip generator to use (null permitted).
        urlGenerator - the URL generator (null permitted).

        Draws the visual representation of a single data item.
        Specified by:
        drawItem in interface XYItemRenderer
        Overrides:
        drawItem in class XYAreaRenderer2
        Parameters:
        g2 - the graphics device.
        state - the renderer state.
        dataArea - the area within which the data is being drawn.
        info - collects information about the drawing.
        plot - the plot (can be used to obtain standard color information etc).
        domainAxis - the domain axis.
        rangeAxis - the range axis.
        dataset - the dataset.
        series - the series index (zero-based).
        item - the item index (zero-based).

      • getStackValues

        private double[] getStackValues​(TableXYDataset dataset,
                                int series,
                                int index)
        Calculates the stacked values (one positive and one negative) of all series up to, but not including, series for the specified item. It returns [0.0, 0.0] if series is the first series.
        Parameters:
        dataset - the dataset (null not permitted).
        series - the series index.
        index - the item index.
        Returns:
        An array containing the cumulative negative and positive values for all series values up to but excluding series for index.

      • averageStackValues

        private double[] averageStackValues​(double[] stack1,
                                    double[] stack2)
        Returns a pair of "stack" values calculated as the mean of the two specified stack value pairs.
        Parameters:
        stack1 - the first stack pair.
        stack2 - the second stack pair.
        Returns:
        A pair of average stack values.

      • adjustedStackValues

        private double[] adjustedStackValues​(double[] stack1,
                                     double[] stack2)
        Calculates adjusted stack values from the supplied values. The value is the mean of the supplied values, unless either of the supplied values is zero, in which case the adjusted value is zero also.
        Parameters:
        stack1 - the first stack pair.
        stack2 - the second stack pair.
        Returns:
        A pair of average stack values.
