All Implemented Interfaces:

javax.accessibility.Accessible, GeneralConstants, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, SpaceConstants

public class Curve

extends javax.swing.JPanel

implements SpaceConstants, GeneralConstants

Visual representation of curve plotting.
A Curve is a JPanel, so it can be used directly, but CurveViewer, contains the controls surrounding a Curve.

Constructor Detail

Curve

public Curve(double[][] data)

Constructor from an array containing at the same time X and Y values.
Meaning of parameter 'data' :
data[0] contains the values of the X axis ;
data[1] contains the values of the first quantity on the Y axis ;
data[2] contains the values of the second quantity on the Y axis ;
etc...

Throws:

java.lang.IllegalArgumentException - if the arrays data[0], data[1] etc... are not all of the same length (for all represented curves, a y value must correspond to a x value).

Method Detail

getAllY

public double[][] getAllY()

Returns the values of the Y axis, for all the curves.

getData

public double[][] getData()

Returns the data displayed by this curve.
If the returned value is called 'data' :
data[0] contains the values of the X axis ;
data[1] contains the values of the first curve on the Y axis ;
data[2] contains the values of the second curve on the Y axis ;
etc...

getNbX

public double getNbX()

Returns the number of X values.

getNbY

public double getNbY()

Returns the number of curves held by this Curve .

getXValues

public double[] getXValues()

Returns the values of the X axis.

getY

public double[] getY(int whichY)

Returns the values of the Y axis for the requested curve.

Parameters:

whichY - index of the requested curve, starting to 1.

Throws:

java.lang.ArrayIndexOutOfBoundsException - if the whichYth curve does not exist.

getY

public double getY(int whichY,
                   double x)

Returns the values of the Y axis for the requested curve. A Lagrange polynom is used to interpolate.

Parameters:

whichY - index of the requested curve, starting to 1.

Throws:

java.lang.ArrayIndexOutOfBoundsException - if the whichYth curve does not exist.

paintComponent

public void paintComponent(java.awt.Graphics g)

Paints the curve on its display area.

Overrides:

paintComponent in class javax.swing.JComponent

setData

public void setData(double[][] data)

Sets the data displayed by this curve.

toString

public java.lang.String toString()

Returns a String representation of this curve.

Overrides:

toString in class java.awt.Component
