Method Detail
-
getDisplayStart
public double getDisplayStart()
Returns the display start value.- Returns:
- The display start value.
-
getDisplayEnd
public double getDisplayEnd()
Returns the display end value.- Returns:
- The display end value.
-
setDisplayRange
public void setDisplayRange(double start, double end)
Sets the display range. The values will be mapped to the fixed range if necessary.- Parameters:
start
- the start value.end
- the end value.
-
autoAdjustRange
protected void autoAdjustRange()
This method should calculate a range that will show all the data values. For now, it just sets the axis range to the fixedRange.- Overrides:
autoAdjustRange
in classNumberAxis
-
valueToJava2D
public double valueToJava2D(double value, Rectangle2D area, org.jfree.ui.RectangleEdge edge)
Translates a data value to a Java2D coordinate.- Overrides:
valueToJava2D
in classNumberAxis
- Parameters:
value
- the value.area
- the area.edge
- the edge.- Returns:
- A Java2D coordinate.
- See Also:
NumberAxis.java2DToValue(double, Rectangle2D, RectangleEdge)
-
java2DToValue
public double java2DToValue(double java2DValue, Rectangle2D area, org.jfree.ui.RectangleEdge edge)
Translates a Java2D coordinate into a data value.- Overrides:
java2DToValue
in classNumberAxis
- Parameters:
java2DValue
- the Java2D coordinate.area
- the area.edge
- the edge.- Returns:
- The Java2D coordinate.
- See Also:
NumberAxis.valueToJava2D(double, Rectangle2D, RectangleEdge)
-
resizeRange
public void resizeRange(double percent)
Increases or decreases the axis range by the specified percentage about the central value and sends anAxisChangeEvent
to all registered listeners.To double the length of the axis range, use 200% (2.0). To halve the length of the axis range, use 50% (0.5).
- Overrides:
resizeRange
in classValueAxis
- Parameters:
percent
- the resize factor.- See Also:
ValueAxis.resizeRange(double, double)
-
resizeRange
public void resizeRange(double percent, double anchorValue)
Increases or decreases the axis range by the specified percentage about the specified anchor value and sends anAxisChangeEvent
to all registered listeners.To double the length of the axis range, use 200% (2.0). To halve the length of the axis range, use 50% (0.5).
- Overrides:
resizeRange
in classValueAxis
- Parameters:
percent
- the resize factor.anchorValue
- the new central value after the resize.- See Also:
ValueAxis.resizeRange(double)
-
lengthToJava2D
public double lengthToJava2D(double length, Rectangle2D area, org.jfree.ui.RectangleEdge edge)
Converts a length in data coordinates into the corresponding length in Java2D coordinates.- Overrides:
lengthToJava2D
in classValueAxis
- Parameters:
length
- the length.area
- the plot area.edge
- the edge along which the axis lies.- Returns:
- The length in Java2D coordinates.
-
equals
public boolean equals(Object obj)

equals
in classNumberAxis
- Parameters:
obj
- the object (null
permitted).- Returns:
- A boolean.
