  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, LegendItemSource, CategoryItemRenderer, org.jfree.util.PublicCloneable

    public class ScatterRenderer
    extends AbstractCategoryItemRenderer
    implements java.lang.Cloneable, org.jfree.util.PublicCloneable, java.io.Serializable
    A renderer that handles the multiple values from a MultiValueCategoryDataset by plotting a shape for each value for each given item in the dataset. The example shown here is generated by the ScatterRendererDemo1.java program included in the JFreeChart Demo Collection:

      • getUseSeriesOffset

        public boolean getUseSeriesOffset()
        Returns the flag that controls whether or not the x-position for each data item is offset within the category according to the series.
        Returns:
        A boolean.
        See Also:
        setUseSeriesOffset(boolean)
      • setUseSeriesOffset

        public void setUseSeriesOffset​(boolean offset)
        Sets the flag that controls whether or not the x-position for each data item is offset within its category according to the series, and sends a RendererChangeEvent to all registered listeners.
        Parameters:
        offset - the offset.
        See Also:
        getUseSeriesOffset()
      • getItemMargin

        public double getItemMargin()
        Returns the item margin, which is the gap between items within a category (expressed as a percentage of the overall category width). This can be used to match the offset alignment with the bars drawn by a BarRenderer).
        Returns:
        The item margin.
        See Also:
        setItemMargin(double), getUseSeriesOffset()
      • setItemMargin

        public void setItemMargin​(double margin)
        Sets the item margin, which is the gap between items within a category (expressed as a percentage of the overall category width), and sends a RendererChangeEvent to all registered listeners.
        Parameters:
        margin - the margin (0.0 <= margin < 1.0).
        See Also:
        getItemMargin(), getUseSeriesOffset()
      • setDrawOutlines

        public void setDrawOutlines​(boolean flag)
        Sets the flag that controls whether outlines are drawn for shapes, and sends a RendererChangeEvent to all registered listeners.

        In some cases, shapes look better if they do NOT have an outline, but this flag allows you to set your own preference.

        Parameters:
        flag - the flag.
        See Also:
        getDrawOutlines()
      • getUseOutlinePaint

        public boolean getUseOutlinePaint()
        Returns the flag that controls whether the outline paint is used for shape outlines. If not, the regular series paint is used.
        Returns:
        A boolean.
        See Also:
        setUseOutlinePaint(boolean)
      • getItemShapeFilled

        public boolean getItemShapeFilled​(int series,
                                          int item)
        Returns the flag used to control whether or not the shape for an item is filled. The default implementation passes control to the getSeriesShapesFilled method. You can override this method if you require different behaviour.
        Parameters:
        series - the series index (zero-based).
        item - the item index (zero-based).
        Returns:
        A boolean.
      • getSeriesShapesFilled

        public boolean getSeriesShapesFilled​(int series)
        Returns the flag used to control whether or not the shapes for a series are filled.
        Parameters:
        series - the series index (zero-based).
        Returns:
        A boolean.
      • setSeriesShapesFilled

        public void setSeriesShapesFilled​(int series,
                                          java.lang.Boolean filled)
        Sets the 'shapes filled' flag for a series and sends a RendererChangeEvent to all registered listeners.
        Parameters:
        series - the series index (zero-based).
        filled - the flag.
      • setSeriesShapesFilled

      • getUseFillPaint

        public boolean getUseFillPaint()
