public class LineChart

extends JPanel

A simple chart showing one or more line graphs. As the mouse moves over the chart, a tooltip displays the coordinates of the points. To use the chart, call the setXXX methods in roughly the order they appear here. Only handles y ≥ 0, and always displays the y-axis. The x-coordinates in the line graphs are the consecutive integers 0, 1, 2, ....

LineChart

public LineChart()

Method Detail

setMaxY

public void setMaxY(float max)

Sets the maximum y value.

setTitles

public void setTitles(String title,
                      String xaxis,
                      String yaxis)

Sets the titles.

setData

public void setData(float[][] dd,
                    String[] l,
                    Color[] c)

Main method to set the chart's data.

Parameters:

dd - Holds the y values. Of size (number of x-coordinates) × (number of line graphs).

l - Labels for the x values. Of length (number of x-coordinates). If it's null, no labels are used.

c - Colors for the line graphs. Of length (number of line graphs).

Throws:

NullPointerException - If dd is null.

setDataSetVisible

public void setDataSetVisible(int i,
                              boolean isVisible)

Set the visibility of the i-th data series (default true).

setSignificantFigures

public void setSignificantFigures(int sigFig)

Sets the number of significant figures (default 3) in the labels on the y-axis. See Format.roundToSigFig(float, int) for restrictions.

getMinimumSize

public Dimension getMinimumSize()

getPreferredSize

public Dimension getPreferredSize()

paintComponent

protected void paintComponent(Graphics g)

setToolTip

protected void setToolTip(MouseEvent e)

Sets a tooltip on this LineChart.

main

public static void main(String[] args)

Takes arguments u0 v0 u1 v1 u2 v2, etc., all ≥ 0, and plots a chart with two line graphs, one for u and one for v. If there is no data, plots two sine waves.
