Detailed Description

This class provides tools to create and manage scatter plots.

Using the ScatterChart class is the simplest way to produce scatter plots only. Each ScatterChart object is linked with a umontreal.ssj.charts.XYListSeriesCollection data set.

Constructor & Destructor Documentation

◆ ScatterChart() [1/5]

ScatterChart	(	String	title,
		String	XLabel,
		String	YLabel,
		double...	data[][]
	)

Initializes a new ScatterChart instance with data data.

title is a title, XLabel is a short description of the \(x\)-axis and YLabel a short description of the \(y\)-axis. The input parameter data represents sets of plotting data. For example, if one \(n\)-row matrix data1 is given as argument data, then the first row data1 \([0]\) represents the \(x\)-coordinate vector, and every other row data1 \([i], i=1,…, n-1\), represents the \(y\)-coordinates of a set of points. Therefore matrix data1 corresponds to \(n-1\) sets of points, all with the same \(x\)-coordinates. However, one may want to plot sets of points with different \(x\)-coordinates. In that case, one should give the points as matrices with two rows. For examples, if the argument data is made of three 2-row matrices data1, data2 and data3, then they represents three different sets of points, data* \([0]\) giving the \(x\)-coordinates, and data* \([1]\) the \(y\)-coordinates of the points.

Parameters

title	chart title.
XLabel	Label on \(x\)-axis.
YLabel	Label on \(y\)-axis.
data	series of point sets.

◆ ScatterChart() [2/5]

ScatterChart	(	String	title,
		String	XLabel,
		String	YLabel,
		double	data[][],
		int	numPoints
	)

Initializes a new ScatterChart instance with sets of points data.

title is a title, XLabel is a short description of the \(x\)-axis, and YLabel a short description of the \(y\)-axis. If data is a \(n\)-row matrix, then the first row data \([0]\) represents the \(x\)-coordinate vector, and every other row data \([i], i=1,…, n-1\), represents a \(y\)-coordinate vector. Therefore matrix data \([i][ ]\), \(i=0,…, n-1\), corresponds to \(n-1\) sets of points, all with the same \(x\)-coordinates. However, only the first numPoints of each set data \([i]\) (i.e. the first numPoints columns of each row) will be plotted.

Parameters

title	chart title.
XLabel	Label on \(x\)-axis.
YLabel	Label on \(y\)-axis.
data	series of point sets.
numPoints	Number of points to plot

◆ ScatterChart() [3/5]

ScatterChart	(	String	title,
		String	XLabel,
		String	YLabel,
		double	data[][],
		int	x,
		int	y
	)

Initializes a new ScatterChart instance using subsets of data.

data[x][.] will form the \(x\)-coordinates and data[y][.] will form the \(y\)-coordinates of the chart. title sets a title, XLabel is a short description of the \(x\)-axis, and YLabel is a short description of the \(y\)-axis. Warning: if the new \(x\)-axis coordinates are not monotone increasing, then they will automatically be sorted in increasing order so the points will be reordered, but the original data is not changed.

Parameters

title	chart title.
XLabel	Label on \(x\)-axis.
YLabel	Label on \(y\)-axis.
data	series of point sets.
x	Index of data forming the \(x\)-coordinates
y	Index of data forming the \(y\)-coordinates

◆ ScatterChart() [4/5]

ScatterChart	(	String	title,
		String	XLabel,
		String	YLabel,
		DoubleArrayList...	data
	)

Initializes a new ScatterChart instance with data data.

The input parameter data represents a set of plotting data. A DoubleArrayList from the Colt library is used to store the data. The description is similar to the above constructor with double[]... data.

Parameters

title	chart title.
XLabel	Label on \(x\)-axis.
YLabel	Label on \(y\)-axis.
data	series of point sets.

◆ ScatterChart() [5/5]

ScatterChart	(	String	title,
		String	XLabel,
		String	YLabel,
		XYSeriesCollection	data
	)

Initializes a new ScatterChart instance with data data.

The input parameter data represents a set of plotting data. org.jfree.data.xy.XYSeriesCollection is a JFreeChart container class to store \(XY\) plots.

Parameters

title	chart title.
XLabel	Label on \(x\)-axis.
YLabel	Label on \(y\)-axis.
data	series collection.

Member Function Documentation

◆ add() [1/3]

int add	(	double []	x,
		double []	y,
		String	name,
		String	plotStyle
	)

Adds a data series into the series collection.

Vector x represents the \(x\)-coordinates and vector y represents the \(y\)-coordinates of the series. name and plotStyle are the name and the plot style associated to the series.

Parameters

x	\(x_i\) coordinates.
y	\(y_i\) coordinates.
name	Name of the series.
plotStyle	Plot style of the series.

Returns: Integer that represent the new point set’s position in the JFreeChart XYSeriesCollection object.

◆ add() [2/3]

int add	(	double []	x,
		double []	y
	)

Adds a data series into the series collection.

Vector x represents the \(x\)-coordinates and vector y represents the \(y\)-coordinates of the series.

Parameters

x	\(x_i\) coordinates.
y	\(y_i\) coordinates.

Returns: Integer that represent the new point set’s position in the JFreeChart XYSeriesCollection object.

◆ add() [3/3]

int add	(	double []	x,
		double []	y,
		int	numPoints
	)

Adds a data series into the series collection.

Vector x represents the \(x\)-coordinates and vector y represents the \(y\)-coordinates of the series. Only the first numPoints of x and y will be taken into account for the new series.

Parameters

x	\(x_i\) coordinates.
y	\(y_i\) coordinates.
numPoints	Number of points to add.

Returns: Integer that represent the new point set’s position in the JFreeChart XYSeriesCollection object.

◆ getSeriesCollection()

XYListSeriesCollection getSeriesCollection ( )

Returns the chart’s dataset.

Returns: the chart’s dataset.

◆ setSeriesCollection()

void setSeriesCollection ( XYListSeriesCollection dataset )

Links a new dataset to the current chart.

Parameters

dataset new dataset.

◆ setTicksSynchro()

void setTicksSynchro ( int s )

Synchronizes \(X\)-axis ticks to the \(s\)-th series \(x\)-values.

Parameters

s	series used to define ticks.

◆ view()

JFrame view	(	int	width,
		int	height
	)

Displays chart on the screen using Swing.

This method creates an application containing a chart panel displaying the chart. The created frame is positioned on-screen, and displayed before it is returned. The width and the height of the chart are measured in pixels.

Parameters

width	frame width in pixels.
height	frame height in pixels.

Returns: frame containing the chart.
