Grachov (DG); 043 * 23-Nov-2001 : Overhauled auto tick unit code for all axes (DG); 044 * 12-Dec-2001 : Minor change due to grid lines bug fix (DG); 045 * 08-Jan-2002 : Added flag allowing the axis to be 'inverted'. That is, run 046 * from positive to negative. Added default values to 047 * constructors (DG); 048 * 16-Jan-2002 : Added an optional crosshair, based on the implementation by 049 * Jonathan Nash (DG); 050 * 25-Feb-2002 : Updated constructors for new autoRangeStickyZero flag (DG); 051 * 19-Apr-2002 : drawVerticalString() is now drawRotatedString() in 052 * RefineryUtilities (DG); 053 * 25-Jun-2002 : Removed redundant import (DG); 054 * 25-Jul-2002 : Changed order of parameters in ValueAxis constructor (DG); 055 * 06-Aug-2002 : Modified draw method to not draw axis label if label is empty 056 * String (RA); 057 * 05-Sep-2002 : Updated constructor for changes in the Axis class, and changed 058 * draw method to observe tickMarkPaint (DG); 059 * 22-Sep-2002 : Fixed errors reported by Checkstyle (DG); 060 * 08-Nov-2002 : Moved to new package com.jrefinery.chart.axis (DG); 061 * 20-Jan-2003 : Removed unnecessary constructors (DG); 062 * 26-Mar-2003 : Implemented Serializable (DG); 063 * 13-May-2003 : Merged HorizontalNumberAxis3D and VerticalNumberAxis3D (DG); 064 * 21-Aug-2003 : Updated draw() method signature (DG); 065 * 07-Nov-2003 : Modified refreshTicks method signature (DG); 066 * 067 */ 068 069 package org.jfree.chart.axis; 070 071 import java.awt.Graphics2D; 072 import java.awt.geom.Rectangle2D; 073 import java.io.Serializable; 074 import java.util.List; 075 076 import org.jfree.chart.Effect3D; 077 import org.jfree.chart.plot.CategoryPlot; 078 import org.jfree.chart.plot.PlotRenderingInfo; 079 import org.jfree.ui.RectangleEdge; 080 081 /** 082 * A standard linear value axis, for values displayed vertically. 083 * 084 * @author Serge V.
