        The font (possibly null).
      • setItemLabelFont

        public void setItemLabelFont​(Font font)
        Deprecated.
        This method should no longer be used (as of version 1.0.6). It is sufficient to rely on setSeriesItemLabelFont(int, Font) and setBaseItemLabelFont(Font).
        Sets the item label font for ALL series and sends a RendererChangeEvent to all registered listeners. You can set this to null if you prefer to set the font on a per series basis.
        Parameters:
        font - the font (null permitted).
      • getItemLabelPaint

        public Paint getItemLabelPaint()
        Deprecated.
        This method should no longer be used (as of version 1.0.6). It is sufficient to rely on getSeriesItemLabelPaint(int) and getBaseItemLabelPaint().
        Returns the paint used for all item labels. This may be null, in which case the per series paint settings will apply.
        Returns:
        The paint (possibly null).
      • getCreateEntities

        public Boolean getCreateEntities()
        Deprecated.
        This method should no longer be used (as of version 1.0.6). It is sufficient to rely on getSeriesCreateEntities(int) and getBaseCreateEntities().
        Returns the flag that controls whether or not chart entities are created for the items in ALL series. This flag overrides the per series and default settings - you must set it to null if you want the other settings to apply.
        Returns:
        The flag (possibly null).
      • setCreateEntities

        public void setCreateEntities​(Boolean create)
        Deprecated.
        This method should no longer be used (as of version 1.0.6). It is sufficient to rely on setSeriesCreateEntities(int, Boolean) and setBaseCreateEntities(boolean).
        Sets the flag that controls whether or not chart entities are created for the items in ALL series, and sends a RendererChangeEvent to all registered listeners. This flag overrides the per series and default settings - you must set it to null if you want the other settings to apply.
        Parameters:
        create - the flag (null permitted).
      • setCreateEntities

        public void setCreateEntities​(Boolean create,
                                      boolean notify)
        Deprecated.
        This method should no longer be used (as of version 1.0.6). It is sufficient to rely on setSeriesItemLabelFont(int, Font, boolean) and setBaseItemLabelFont(Font, boolean).
        Sets the flag that controls whether or not chart entities are created for the items in ALL series, and sends a RendererChangeEvent to all registered listeners. This flag overrides the per series and default settings - you must set it to null if you want the other settings to apply.
        Parameters:
        create - the flag (null permitted).
        notify - notify listeners?
