    Constructor Description
    XYLineAnnotation​(double x1, double y1, double x2, double y2)
    Creates a new annotation that draws a line from (x1, y1) to (x2, y2) where the coordinates are measured in data space (that is, against the plot's axes).
    XYLineAnnotation​(double x1, double y1, double x2, double y2, Stroke stroke, Paint paint)
    Creates a new annotation that draws a line from (x1, y1) to (x2, y2) where the coordinates are measured in data space (that is, against the plot's axes).

    • XYLineAnnotation

      public XYLineAnnotation​(double x1, double y1, double x2, double y2)
      Creates a new annotation that draws a line from (x1, y1) to (x2, y2) where the coordinates are measured in data space (that is, against the plot's axes).
      Parameters:
      x1 - the x-coordinate for the start of the line.
      y1 - the y-coordinate for the start of the line.
      x2 - the x-coordinate for the end of the line.
      y2 - the y-coordinate for the end of the line.

    • draw

      public void draw​(Graphics2D g2, XYPlot plot, Rectangle2D dataArea, ValueAxis domainAxis, ValueAxis rangeAxis)
      Draws the annotation. This method is called by the XYPlot class, you won't normally need to call it yourself.
      Specified by:
      draw in interface XYAnnotation
      Parameters:
      g2 - the graphics device.
      plot - the plot.
      dataArea - the data area.
      domainAxis - the domain axis.
      rangeAxis - the range axis.

    • equals

      public boolean equals​(Object object)
      Tests this object for equality with an arbitrary object.
      Overrides:
      equals in class Object
      Parameters:
      object - the object to test against (null permitted).
      Returns:
      true or false.

    • clone

      public Object clone() throws CloneNotSupportedException
      Returns a clone of the annotation.
      Returns:
      A clone.
      Throws:
      CloneNotSupportedException - if the annotation can't be cloned.
