| Axis2D | | public class Axis2D extends Line2D implements Cloneable,Serializable(Code) | | An axis as a graduated line.
Axis2D objets are really
Line2D objects with a
Graduation . Because axis are
Line2D , they can be
located anywhere in a widget with any orientation. Lines are drawn from starting
point
(
,
)
to end point
(
,
),
using a graduation from minimal value
Graduation.getMinimum to maximal
value
Graduation.getMaximum .
Note the line's coordinates (x1,y1) and
(x2,y2) are completly independant of
graduation minimal and maximal values. Line's coordinates should be expressed in
some units convenient for rendering, as pixels or point (1/72 of inch). On the
opposite, graduation can have any arbitrary units, which is given by
Graduation.getUnit . The static method
Axis2D.createAffineTransform can
be used for mapping logical coordinates to pixels coordinates for an arbitrary
pair of
Axis2D objects, which doesn't need to be perpendicular.

| Axis2D | | public Axis2D(Graduation graduation)(Code) | | Constructs an axis with the specified graduation.
|
| createAffineTransform | | public static AffineTransform createAffineTransform(Axis2D xAxis, Axis2D yAxis)(Code) | | Creates an affine transform mapping logical to pixels coordinates for a pair
of axis. The affine transform will maps coordinates in the following way:
- For each input coordinates (x,y), the x and
y values are expressed in the same units than the
xAxis and
yAxis graduations, respectively.
- The output point is the pixel's coordinates for the (x,y)
values. Changing the x value move the pixel location in parallel with
the
xAxis , which may or may not be horizontal. Changing the y
value move the pixel location in parallel with the
yAxis , which may or
may not be vertical.
Parameters:
xAxis - The x axis. This axis doesn't have to be horizontal;it can have any orientation, including vertical.
Parameters:
yAxis - The y axis. This axis doesn't have to be vertical;it can have any orientation, including horizontal. An affine transform mapping logical to pixels coordinates. |
| getGraduation | | public Graduation getGraduation()(Code) | | Returns the axis's graduation.
|
| getLength | | public synchronized double getLength()(Code) | | Returns the axis length. This is the distance between starting point (@link #getP1 P1})
and end point (
Axis2D.getP2 P2 ). This length is usually measured in pixels or points
(1/72 of inch).
|
| getP1 | | public synchronized Point2D getP1()(Code) | | Returns the (x,y) coordinates of the start point.
By convention, those coordinates should be in pixels or points (1/72 of
inch) for proper positionning of ticks and labels.
|
| getP2 | | public synchronized Point2D getP2()(Code) | | Returns the (x,y) coordinates of the end point.
By convention, those coordinates should be in pixels or points (1/72 of
inch) for proper positionning of ticks and labels.
|
| getPathIterator | | public java.awt.geom.PathIterator getPathIterator(AffineTransform transform)(Code) | | Returns an iterator object that iterates along the
Axis2D boundary
and provides access to the geometry of the shape outline. The shape includes
the axis line, graduation and labels. If an optional
AffineTransform is specified, the coordinates returned in the iteration are transformed accordingly.
|
| getPathIterator | | public synchronized java.awt.geom.PathIterator getPathIterator(AffineTransform transform, double flatness)(Code) | | Returns an iterator object that iterates along the
Axis2D boundary
and provides access to the geometry of the shape outline. The shape includes
the axis line, graduation and labels. If an optional
AffineTransform is specified, the coordinates returned in the iteration are transformed accordingly.
|
| getRenderingHint | | public synchronized Object getRenderingHint(RenderingHints.Key key)(Code) | | Returns the value of a single preference for the rendering algorithms. Hint categories
include controls for label fonts and colors. Some of the keys and their associated values
are defined in the
Graduation interface.
Parameters:
key - The key corresponding to the hint to get. An object representing the value for the specified hint key, or null if no value is associated to the specified key.

| getX1 | | public double getX1()(Code) | | Returns the x coordinate of the start point. By convention,
this coordinate should be in pixels or points (1/72 of inch) for proper
positionning of ticks and labels.

See Also: Axis2D.getX2

| getX2 | | public double getX2()(Code) | | Returns the x coordinate of the end point. By convention,
this coordinate should be in pixels or points (1/72 of inch) for proper
positionning of ticks and labels.

| getY1 | | public double getY1()(Code) | | Returns the y coordinate of the start point. By convention,
this coordinate should be in pixels or points (1/72 of inch) for proper
positionning of ticks and labels.

| getY2 | | public double getY2()(Code) | | Returns the y coordinate of the end point. By convention,

positionning of ticks and labels.

| isLabelClockwise | | public boolean isLabelClockwise()(Code) | | Returns
true if the axis would have to rotate clockwise in order to
overlaps its graduation.
|
| paint | | public synchronized void paint(Graphics2D graphics)(Code) | | Draw this axis in the specified graphics context. This method is equivalents
to
Graphics2D.draw(this) . However, this method may be slightly
faster and produce better quality output.
Parameters:
graphics - The graphics context to use for drawing. |
| setLabelClockwise | | public synchronized void setLabelClockwise(boolean c)(Code) | | Sets the label's locations relative to this axis. Value
true means
that the axis would have to rotate clockwise in order to overlaps its graduation.
Value
false means that the axis would have to rotate counter-clockwise
in order to overlaps its graduation.
|
| setLine | | public synchronized void setLine(double x1, double y1, double x2, double y2) throws IllegalArgumentException(Code) | | Sets the location of the endpoints of this
Axis2D to the specified
coordinates. Coordinates should be in pixels (for screen rendering) or points
(for paper rendering). Using points units make it easy to render labels with
a raisonable font size, no matter the screen resolution or the axis graduation.
Parameters:
x1 - Coordinate x of starting point.
Parameters:
y1 - Coordinate y of starting point
Parameters:
x2 - Coordinate x of end point.
Parameters:
y2 - Coordinate y of end point.
throws:
IllegalArgumentException - If a coordinate is NaN or infinite.

Parameters:
key - The key of the hint to be set.
