39  * Changes
40  * -------
41  * 31-Oct-2001 : Version 1 contributed by Serge V. Grachov (DG);
42  * 23-Nov-2001 : Overhauled auto tick unit code for all axes (DG);
43  * 12-Dec-2001 : Minor change due to grid lines bug fix (DG);
44  * 08-Jan-2002 : Added flag allowing the axis to be 'inverted'. That is, run
45  * from positive to negative. Added default values to
46  * constructors (DG);
47  * 16-Jan-2002 : Added an optional crosshair, based on the implementation by
48  * Jonathan Nash (DG);
49  * 25-Feb-2002 : Updated constructors for new autoRangeStickyZero flag (DG);
50  * 19-Apr-2002 : drawVerticalString() is now drawRotatedString() in
51  * RefineryUtilities (DG);
52  * 25-Jun-2002 : Removed redundant import (DG);
53  * 25-Jul-2002 : Changed order of parameters in ValueAxis constructor (DG);
54  * 06-Aug-2002 : Modified draw method to not draw axis label if label is empty
55  * String (RA);
56  * 05-Sep-2002 : Updated constructor for changes in the Axis class, and changed
57  * draw method to observe tickMarkPaint (DG);
58  * 22-Sep-2002 : Fixed errors reported by Checkstyle (DG);
59  * 08-Nov-2002 : Moved to new package com.jrefinery.chart.axis (DG);
60  * 20-Jan-2003 : Removed unnecessary constructors (DG);
61  * 26-Mar-2003 : Implemented Serializable (DG);
62  * 13-May-2003 : Merged HorizontalNumberAxis3D and VerticalNumberAxis3D (DG);
63  * 21-Aug-2003 : Updated draw() method signature (DG);
64  * 07-Nov-2003 : Modified refreshTicks method signature (DG);
