boolean |
equals(java.lang.Object obj)
Tests the axis for equality with an arbitrary object. |
java.lang.Class |
getAutoRangeTimePeriodClass()
Returns the class used to create the first and last time periods for the axis range when the auto-range flag is set to true . |
RegularTimePeriod |
getFirst()
Returns the first time period in the axis range. |
PeriodAxisLabelInfo[] |
getLabelInfo()
Returns an array of label info records. |
RegularTimePeriod |
getLast()
Returns the last time period in the axis range. |
Range |
getRange()
Returns the range for the axis. |
java.util.TimeZone |
getTimeZone()
Returns the time zone used to convert the periods defining the axis range into absolute milliseconds. |
double |
java2DToValue(double java2DValue,
java.awt.geom.Rectangle2D area,
org.jfree.ui.RectangleEdge edge)
Converts a coordinate in Java2D space to the corresponding data value, assuming that the axis runs along one edge of the specified dataArea. |

refreshTicks(java.awt.Graphics2D g2,
AxisState state,
java.awt.geom.Rectangle2D plotArea,
java.awt.geom.Rectangle2D dataArea,
org.jfree.ui.RectangleEdge edge)

java.awt.geom.Rectangle2D plotArea,
org.jfree.ui.RectangleEdge edge,
AxisSpace space)
Estimates the space (height or width) required to draw the axis. |
void |
setAutoRangeTimePeriodClass(java.lang.Class c)
Sets the class used to create the first and last time periods for the axis range when the auto-range flag is set to true and sends an AxisChangeEvent
to all registered listeners. |
void |
setFirst(RegularTimePeriod first)
Sets the first time period in the axis range and sends an AxisChangeEvent to
all registered listeners. |
void |
setLabelInfo(PeriodAxisLabelInfo[] info)
Sets the array of label info records. |
void |
setLast(RegularTimePeriod last)
Sets the last time period in the axis range and sends an AxisChangeEvent to
all registered listeners. |
void |
setTimeZone(java.util.TimeZone zone)
Sets the time zone that is used to convert the time periods into absolute milliseconds. |
double |
valueToJava2D(double value,
java.awt.geom.Rectangle2D area,
org.jfree.ui.RectangleEdge edge)
Converts a data value to a coordinate in Java2D space, assuming that the axis runs along one edge of the specified dataArea. |
