Parameters:

layout - The LayoutManager to be used

LineGraph

public LineGraph(LayoutManager layout,
                 boolean isDoubleBuffered)

Parameters:

layout - The LayoutManager to be used

Method Detail

setData

public void setData(double[][] data)

setTitle

public void setTitle(String title)

setXAxisTitle

public void setXAxisTitle(String title)

setYAxisTitle

public void setYAxisTitle(String title)

setXAxisLabels

public void setXAxisLabels(String[] labels)

setYAxisLabels

public void setYAxisLabels(String[] label)

setWidth

public void setWidth(int w)

setHeight

public void setHeight(int h)

paintComponent

public void paintComponent(Graphics g)

Overrides:

paintComponent in class JComponent

createShapes

public Shape[] createShapes(int count)

Since we only have 4 shapes, the method will start with the first shape and keep cycling through the shapes in order.

Parameters:

count - The number of shapes to be created

Returns:

the first n shapes

nextShape

public Shape nextShape()

Return the next shape

Returns:

the next shape

createStrokes

public Stroke[] createStrokes(int count)

Create a given number of Strokes

Parameters:

count - The number of strokes to be created

Returns:

the first count strokes

nextStroke

public Stroke nextStroke()

method always return a new BasicStroke with 1.0f weight

Returns:

a new BasicStroke with 1.0f weight

createPaint

public Paint[] createPaint(int count)

return an array of Paint with different colors. The current implementation will cycle through 12 colors if a line graph has more than 12 entries

Parameters:

count - The number of Paints to be created

Returns:

an array of Paint with different colors

nextPaint

public Paint nextPaint()

The method will return the next paint color in the PAINT_ARRAY. Rather than return a random color, we want it to always go through the same sequence. This way, the same charts will always use the same color and make it easier to compare side by side.

Returns:

the next paint color in the PAINT_ARRAY
