Constructor Detail

FastScatterPlot

public FastScatterPlot()

Creates an empty plot.

FastScatterPlot

public FastScatterPlot(float[][] data,
                       ValueAxis domainAxis,
                       ValueAxis rangeAxis)

Creates a new fast scatter plot.

The data is an array of x, y values: data[0][i] = x, data[1][i] = y.

Parameters:

data - the data.

domainAxis - the domain (x) axis.

rangeAxis - the range (y) axis.

Method Detail

getPlotType

public java.lang.String getPlotType()

Returns a short string describing the plot type.

Specified by:

getPlotType in class Plot

Returns:

a short string describing the plot type.

getDomainAxis

public ValueAxis getDomainAxis()

Returns the domain axis for the plot. If the domain axis for this plot is null, then the method will return the parent plot's domain axis (if there is a parent plot).

Returns:

the domain axis.

getRangeAxis

public ValueAxis getRangeAxis()

Returns the range axis for the plot. If the range axis for this plot is null, then the method will return the parent plot's range axis (if there is a parent plot).

Returns:

the range axis.

getPaint

public java.awt.Paint getPaint()

Returns the paint used to plot data points.

Returns:

The paint.

setPaint

public void setPaint(java.awt.Paint paint)

Sets the color for the data points.

Parameters:

paint - the paint.

draw

public void draw(java.awt.Graphics2D g2,
                 java.awt.geom.Rectangle2D plotArea,
                 PlotState parentState,
                 PlotRenderingInfo info)

Draws the fast scatter plot on a Java 2D graphics device (such as the screen or a printer).

Specified by:

draw in class Plot

Parameters:

g2 - the graphics device.

plotArea - the area within which the plot (including axis labels) should be drawn.

parentState - the state from the parent plot, if there is one.

info - collects chart drawing information (null permitted).

render

public void render(java.awt.Graphics2D g2,
                   java.awt.geom.Rectangle2D dataArea,
                   PlotRenderingInfo info,
                   CrosshairInfo crosshairInfo)

Draws a representation of the data within the dataArea region.

The info and crosshairInfo arguments may be null.

Parameters:

g2 - the graphics device.

dataArea - the region in which the data is to be drawn.

info - an optional object for collection dimension information.

crosshairInfo - an optional object for collecting crosshair info.

getDataRange

public Range getDataRange(ValueAxis axis)

Returns the range of data values to be plotted along the axis.

Specified by:

getDataRange in interface ValueAxisPlot

Parameters:

axis - the axis.

Returns:

the range.

zoomHorizontalAxes

public void zoomHorizontalAxes(double factor)

Multiplies the range on the horizontal axis/axes by the specified factor (not yet implemented).

Specified by:

zoomHorizontalAxes in interface ValueAxisPlot

Parameters:

factor - the zoom factor.

zoomHorizontalAxes

public void zoomHorizontalAxes(double lowerPercent,
                               double upperPercent)

Zooms in on the horizontal axes (not yet implemented).

Specified by:

zoomHorizontalAxes in interface ValueAxisPlot

Parameters:

lowerPercent - the new lower bound as a percentage of the current range.

upperPercent - the new upper bound as a percentage of the current range.

zoomVerticalAxes

public void zoomVerticalAxes(double factor)

Multiplies the range on the vertical axis/axes by the specified factor (not yet implemented).

Specified by:

zoomVerticalAxes in interface ValueAxisPlot

Parameters:

factor - the zoom factor.

zoomVerticalAxes

public void zoomVerticalAxes(double lowerPercent,
                             double upperPercent)

Zooms in on the vertical axes (not yet implemented).

Specified by:

zoomVerticalAxes in interface ValueAxisPlot

Parameters:

lowerPercent - the new lower bound as a percentage of the current range.

equals

public boolean equals(java.lang.Object object)

Tests an object for equality with this instance.

Overrides:

equals in class Plot

Parameters:

object - the object to test.

Returns:

A boolean.

clone
