Constructor Detail

MultiHistogram

public MultiHistogram()

Method Detail

setNumBars

public void setNumBars(int bars)

Sets the number of bars.

Parameters:

the - number of bars.

getNumBars

public int getNumBars()

setBarColor

public void setBarColor(java.awt.Color col)

Sets the color of the bars.

Parameters:

the - bar color.

getBarColor

public java.awt.Color getBarColor()

Returns:

the color of the bars.

drawPlot

public void drawPlot(java.lang.Object x,
                     java.lang.Object y)

Description copied from class: PlotViewport

Draws the plot. Currently, only the Auto mode is implemented. This method computes the minimum and maximum values from the x and y inputs. Once these are computed, it calls draw(). Before calling draw(), it sets the enableDraw to true. The enableDraw flag makes sure that the draw() method is called only after the executing drawPlot(). The draw() method is called by many property setter methods to reflect the change.

Overrides:

drawPlot in class PlotViewport

Following copied from class: vis.beans.plotter.PlotViewport

Parameters:

x - the x axis values as an array of primitive data types or String.

y - the y axis values as an array of primitive data types.

plotHistogram

public void plotHistogram(PlotEvent e)

This method plots the histogram. This can be used as a target method for for connecting other beans to the Histogram using plot events.

Parameters:

e - the PlotEvent

drawPlot

public void drawPlot(java.lang.Object data)

Plots the histogram.

Parameters:

data - an array of elements which can be of any Java primitive type.

computeHistogram

public void computeHistogram()

draw

public void draw()

Description copied from class: PlotViewport

This method does the actual drawing. In addition to being called by drawPlot(), this method is called by many setter methods so as to reflect a change in property. draw() calls methods calls methods to create a new plot temeplate, draw X and Y axes, ticks and lables. Some of these methods are ovverriden by sub classes.

Overrides:

draw in class PlotViewport

drawXTicks

public void drawXTicks(java.lang.Object minmax)

Description copied from class: PlotViewport

Draws X ticks.

Overrides:

drawXTicks in class PlotViewport

Following copied from class: vis.beans.plotter.PlotViewport

Parameters:

minmax - an array of size two that holds the X axis minimun maximum value.

drawYTicks

protected void drawYTicks(int[] minmax)

addGraph

public void addGraph(java.lang.Object x,
                     java.lang.Object y)

Description copied from class: PlotViewport

This method adds a graph.

Overrides:

addGraph in class PlotViewport

Following copied from class: vis.beans.plotter.PlotViewport

Parameters:

x - the x axis values as an array of primitive data types or String.

y - the y axis values as an array of primitive data types.

resetPlotViewport

public void resetPlotViewport()

Description copied from class: PlotViewport

Resets the plot viewport.

Overrides:

resetPlotViewport in class PlotViewport

paintGraphs

public void paintGraphs()

Description copied from class: PlotViewport

Paints all the graphs. This method is called by draw() to paint the actual plots.

Overrides:

paintGraphs in class PlotViewport
