Field Detail

legend

protected Legend legend

legend, if there

points

protected DVectorSet points

This is a vector of points to plot. Each point is a DVector, and must contain at least 2 coordinates.

ptype

protected PointType ptype

type of point to draw.

Constructor Detail

PointPlot

public PointPlot(DVectorSet x)

initialize with a set of points.

Method Detail

getPoints

public DVectorSet getPoints()

Returns a pointer to the points being drawn.

setPoints

public void setPoints(DVectorSet x)

Sets the points being drawn. Does not copy data.

minX

public double minX()

Description copied from interface: Graphable2D

minimum x value that will be graphed.

Specified by:

minX in interface Graphable2D

minY

public double minY()

Description copied from interface: Graphable2D

minimum y value that will be graphed.

Specified by:

minY in interface Graphable2D

maxX

public double maxX()

Description copied from interface: Graphable2D

maximum x value that will be graphed.

Specified by:

maxX in interface Graphable2D

maxY

public double maxY()

Description copied from interface: Graphable2D

maximum y value that will be graphed.

Specified by:

maxY in interface Graphable2D

setPointType

public void setPointType(PointType pt)

Set point type to draw.

paintVectorAt

protected void paintVectorAt(int x,
                             int y,
                             DVector v,
                             java.awt.Graphics g)

Draw one of the points somewhere. Note that this doesn't need the DVector, but derived classes might.

getLegend

public Legend getLegend()

get legend

Specified by:

getLegend in interface Graphable2D

setLegend

public void setLegend(PointLegend x)

sets legend.

createLegend

public void createLegend()

creates a new legend

paintGraph

public void paintGraph(java.awt.Graphics g,
                       java.awt.Rectangle r,
                       Graph2D gr)

Description copied from interface: Graphable2D

draw the graph, in a given rectangle. Should not clear the background, since more than 1 could be drawn.
