public class JGraph

extends com.jrefinery.chart.JFreeChartFrame

JFrame able to display and save as a PNG file XYPlots of a number of function series (graps of functions y=f(x)) defined on the same interval [x_min,x_max] and evaluated at evenly spaced points in this interval incuding the endpoints.

The number of points at which each series is sampled can vary from series to series. The series are added to the JGraph by passing the array containing the sample values addSeries(double[], java.lang.String).

Presently only 9 series can be added to the plot. The color array contains only 9 colors. This will be changed in the near future.

Based on JFreeChart by David Gilbert.

Constructor Detail

JGraph

public JGraph(double x_min,
              double x_max)

Constructor initializes chartFrame as a javax.swing.JFrame containing the plot of nSeries series based on the same linear domain x[i]=x_min+(x_max-x_min)*i/n, i=0,1,...,n=nPoints-1.

Parameters:

x_min - minimum x-value

x_max - maximum x-value

Note: the arrays seriesArray and seriesNames can contain more than nSeries series respectively strings. Only the first nSeries items will be displayed.

Method Detail

setYAxisMin

public void setYAxisMin(double y_min)

Set axes labels, title, y-axis minimum

setXAxisLabel

public void setXAxisLabel(java.lang.String xAxisLabel)

setYAxisLabel

public void setYAxisLabel(java.lang.String yAxisLabel)

setTitle

public void setTitle(java.lang.String title)

addSeries

public void addSeries(double[] series,
                      java.lang.String seriesName)

Add a series

Parameters:

series - array containing the values of the series at the gridpoints evenly spaced in [x_min,x_max].

seriesName - name of the series (goes in legend).

saveAsEPS

public void saveAsEPS(java.lang.String filename)
               throws java.io.FileNotFoundException,
                      java.io.IOException

FILE EXPORT

Throws:

java.io.FileNotFoundException

java.io.IOException

saveAsJPEG

public void saveAsJPEG(java.lang.String filename)

Saves the graph in as a JPEG file.

saveAsPNG

public void saveAsPNG()

Saves the graph in as a PNG file (dialogue)

saveAsASCII

public void saveAsASCII(java.lang.String filename)

Saves the "graph" as an ASCII data file by first printing the points in the domain (x-values) and then printing the series (y-values) all as columns separated by commas.

This format is useful for import into more sophisticated tools such as Scigraphica, http://www.scigraphica.sourceforge.net/. These tools then offer much functionality for editing the graph by hand.

The assumption is that all the series are based on the same domain with the same discretization of this domain.

main

public static void main(java.lang.String[] args)
                 throws java.lang.InterruptedException,
                        java.io.FileNotFoundException,
                        java.io.IOException

Test program displaying the graph of three functions f(x)=x^2, g(x)=5-x^2, h(x)=2+x^2/2 and saving the graph as the file testGraph.jpeg.

Throws:

java.lang.InterruptedException

java.io.FileNotFoundException

java.io.IOException
