Constructor Detail

Axis

public Axis(Chart chart)
Contructs an Axis node. Its parent must be a Chart node. This node's "Axis" attribute has itself as a value, so that decendent nodes can easily obtain their controlling axis node.

Parameters:
chart - a Chart object, the parent of this node
Method Detail

mapDeviceToUser

public abstract void mapDeviceToUser(int devX,
                                     int devY,
                                     double[] userXY)
Maps the device coordinates to user coordinates.

Parameters:
devX - an int which specifies the device x-coordinate
devY - an int which specifies the device y-coordinate
userXY - an double[2] array on input, on output, the user coordinates

mapUserToDevice

public abstract void mapUserToDevice(double userX,
                                     double userY,
                                     int[] devXY)
Maps the user coordinates (userX,userY) to the device coordinates devXY.

Parameters:
userX - a double which specifies the user x-coordinate
userY - a double which specifies the user y-coordinate
devXY - an int[2] array on input, on output, the device coordinates

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.

Specified by:
paint in class ChartNode
Parameters:
draw - a Draw object which specifies the chart tree to be rendered on the screen

setupMapping

public abstract 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. Generally, it is safest to call this each time the chart is repainted.
