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, java.awt.Stroke stroke, java.awt.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).

```
    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.

                 PlotRenderingInfo info)
```
    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
    
    Specified by:
    
    draw in class AbstractXYAnnotation
    
    Parameters:
    
    g2 - the graphics device.
    
    plot - the plot.
    
    dataArea - the data area.
    
    domainAxis - the domain axis.
    
    rangeAxis - the range axis.
    
    rendererIndex - the renderer index.
    
    info - if supplied, this info object will be populated with entity information.
  - equals
```
public boolean equals(java.lang.Object obj)
```
    Tests this object for equality with an arbitrary object.
    
    Overrides:
    
    equals in class AbstractXYAnnotation
    
    Parameters:
    
    obj - the object to test against (null permitted).
    
    Returns:
    
    true or false.
  - hashCode
```
public int hashCode()
```
    Returns a hash code.
    
    Overrides:
    
    hashCode in class AbstractXYAnnotation
    
    Returns:
    
    A hash code.
  - clone
```
public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException
```
    Returns a clone of the annotation.
    
    Specified by:
    
    clone in interface org.jfree.util.PublicCloneable
    
    Overrides:
    
    clone in class AbstractAnnotation
    
    Returns:
    
    A clone.
    
    Throws:
    
    java.lang.CloneNotSupportedException - if the annotation can't be cloned.
