 * Changes
 * -------
 * 31-Oct-2001 : Version 1 contributed by Serge V. Grachov (DG);
 * 23-Nov-2001 : Overhauled auto tick unit code for all axes (DG);
 * 12-Dec-2001 : Minor change due to grid lines bug fix (DG);
 * 08-Jan-2002 : Added flag allowing the axis to be 'inverted'.  That is, run
 *               from positive to negative.  Added default values to
 *               constructors (DG);
 * 16-Jan-2002 : Added an optional crosshair, based on the implementation by
 *               Jonathan Nash (DG);
 * 25-Feb-2002 : Updated constructors for new autoRangeStickyZero flag (DG);
 * 19-Apr-2002 : drawVerticalString() is now drawRotatedString() in
 *               RefineryUtilities (DG);
 * 25-Jun-2002 : Removed redundant import (DG);
 * 25-Jul-2002 : Changed order of parameters in ValueAxis constructor (DG);
 * 06-Aug-2002 : Modified draw method to not draw axis label if label is empty
 *               String (RA);
 * 05-Sep-2002 : Updated constructor for changes in the Axis class, and changed
 *               draw method to observe tickMarkPaint (DG);
 * 22-Sep-2002 : Fixed errors reported by Checkstyle (DG);
 * 08-Nov-2002 : Moved to new package com.jrefinery.chart.axis (DG);
 * 20-Jan-2003 : Removed unnecessary constructors (DG);
 * 26-Mar-2003 : Implemented Serializable (DG);
 * 13-May-2003 : Merged HorizontalNumberAxis3D and VerticalNumberAxis3D (DG);
 * 21-Aug-2003 : Updated draw() method signature (DG);
 * 07-Nov-2003 : Modified refreshTicks method signature (DG);
 * ------------- JFREECHART 1.0.x ---------------------------------------------
 * 18-Jan-2006 : Fixed bug 1408904 (axis assumes CategoryPlot) (DG):
 * 16-Apr-2009 : Changed axis line visibility default (DG);
