<DL>
<DD>Returns a bounding vector for the current tick label.
 Units are the same than axis start point
 (<A HREF="../../../org/geotools/axis/Axis2D.html#getX1()"><var>x<sub>1</sub></var></A>,<A HREF="../../../org/geotools/axis/Axis2D.html#getY1()"><var>y<sub>1</sub></var></A>)

 This is usually pixels. This method can be used as in the example below:
