DisplayHistogram

All Implemented Interfaces:

MouseMotionListener, ImageObserver, MenuContainer, Serializable, EventListener

public class DisplayHistogram
extends JComponent
implements MouseMotionListener

This class displays a histogram (instance of Histogram) as a component. Only the first histogram band ins considered for plotting. The component has a tooltip which displays the bin index and bin count for the bin under the mouse cursor.

Constructor Details

DisplayHistogram

public DisplayHistogram(String title)

The constructor for this class, which will set its fields' values and get some information about the histogram.

Parameters:

title - the title of the plot.

Method Details

setBinWidth

public void setBinWidth(int newWidth)

Override the default bin width (for plotting)

setHeight

public void setHeight(int h)

Override the default height for the plot.

Parameters:

h - the new height.

setIndexMultiplier

public void setIndexMultiplier(int i)

Override the index multiplying factor (for bins with width != 1)

setSkipIndexes

public void setSkipIndexes(int i)

Override the index skipping factor (determines how many labels will be printed on the index axis).

setMaxCount

Set the maximum value (used to scale the histogram y-axis). The default value is defined in the constructor and can be overriden with this method.

getMaximumSize

public Dimension getMaximumSize()

This method informs the maximum size of this component, which will be the same as the preferred size.

Overrides:

getMaximumSize in class JComponent

getMinimumSize

public Dimension getMinimumSize()

This method informs the minimum size of this component, which will be the same as the preferred size.

Overrides:

getMinimumSize in class JComponent

getPreferredSize

public Dimension getPreferredSize()

This method informs the preferred size of this component, which will be constant.

Overrides:

getPreferredSize in class JComponent

mouseDragged

public void mouseDragged(MouseEvent e)
