All Implemented Interfaces:

Serializable, Cloneable

public class Polar
extends Axis

This Axis node is used for polar charts. In a polar plot, the (x,y) coordinates in Data nodes are interpreted as (r,theta) values. The "Viewport" attribute for this node is set to [0.1,0.9] by [0.1,0.9].

Constructor Detail

Polar

public Polar(Chart chart)

Create an AxisPolar.

Parameters:

chart - a Chart object, the parent of this node

Method Detail

getAxisR

public AxisR getAxisR()

Return the radius axis node.

Returns:

the AxisR radius axis node

getAxisTheta

public AxisTheta getAxisTheta()

Return the angular axis node.

Returns:

the AxisTheta axis node

getGridPolar

public GridPolar getGridPolar()

Returns the grid.

Returns:

the grid, a GridPolar object

mapDeviceToUser

public void mapDeviceToUser(int devX,
                            int devY,
                            double[] userRT)

Map the device coordinates to polar coordinates.

Specified by:

mapDeviceToUser in class Axis

Parameters:

devX - an int, the device x-coordinate

devY - an int, the device y-coordinate

userRT - a double[2] array in which the user coordinates, (radius,theta), are returned.

mapUserToDevice

public void mapUserToDevice(double userRadius,
                            double userTheta,
                            int[] devXY)

Map the polar coordinates (userRadius,userAngle) to the device coordinates devXY.

Specified by:

mapUserToDevice in class Axis

Parameters:

userRadius - a double, the user radius coordinate

userTheta - a double, the user angle coordinate

devXY - an int[2] array in which the device coordinates are returned.

paint

public void paint(Draw draw)

Paints this node and all of its children. This is normally called only by the paint method in this node's parent.

Overrides:

paint in class Axis

Parameters:

draw - the Draw object to be painted

setupMapping

public void setupMapping()

Initializes the mappings between user and coordinate space. This must be called whenever the screen size, the window or the viewport may have changed.

Specified by:

setupMapping in class Axis
