All Implemented Interfaces:

public class BarGraph
extends javax.swing.JComponent
implements Paintable

BarGraph implements the Drawable interface to draw a bar graphics.graph on a frame. Requires an instance of DoubleDataBean in order to be constructed.
Global variables:

• DoubleDataBean: instance of DoubleDataBean so the graphics.graph is drawn with the proper data
• barwidth: an arbitrary width for each bar in the bar graphics.graph

Since:

JDK 1.3

Constructor Detail

BarGraph

public BarGraph(DoubleDataBean _dd)

Constructor used if only height and width should be set, using defaults for all global variables. Probably would only use this as a test case.

Parameters:

w - Image width (not frame width)

h - Image height (not frame height)

Method Detail

getPreferredSize

public java.awt.Dimension getPreferredSize()

Overrides:

getPreferredSize in class javax.swing.JComponent

getMinimumSize

public java.awt.Dimension getMinimumSize()

Overrides:

getMinimumSize in class javax.swing.JComponent

setBarWidth

public void setBarWidth(int _barwidth)

Sets the arbitrary width of the bars.

Parameters:

_barwidth - Width of each bar

paint

public void paint(java.awt.Graphics g)

Actually paints this data from DoubleDataBean onto an image. The DrawUtil class is a generic utilities class containing all methods which actually handle the painting.

Specified by:

paint in interface Paintable

Overrides:

paint in class javax.swing.JComponent

Parameters:

g - Graphics context for drawing

main

public static void main(java.lang.String[] args)
