jfreeChart

[Marcus Senna]

hey, i am trying to use jfreechart, but i am having problems with importing packages from the file i downloaded. I am using JBuilder 2005, and i am getting the following error.

cannot find symbol; symbol : class ChartFactory, location: package org.jfree.chart at line 3 (3:24)
import requires canonical name for <any> at line 3 (3:24)

Your help would be greatly appreciated. Thanks!!!

Please post the package and import statements from the offending class.

import org.jfree.chart.ChartFactory; //I am not able to import these
import org.jfree.chart.ChartFrame;
import org.jfree.chart.JFreeChart;
import org.jfree.data.general.DefaultPieDataset;
public class First {
/**
* The starting point for the demo.
*
* @param args ignored.
*/
public static void main(String[] args) {
// create a dataset...
DefaultPieDataset dataset = new DefaultPieDataset();
dataset.setValue("Category 1", 43.2);
dataset.setValue("Category 2", 27.9);
dataset.setValue("Category 3", 79.5);
// create a chart...
JFreeChart chart = ChartFactory.createPieChart(
"Sample Pie Chart",
dataset,
true, // legend?
true, // tooltips?
false // URLs?
);
// create and display a frame...
ChartFrame frame = new ChartFrame("First", chart);
frame.pack();
frame.setVisible(true);
}
}

How did you add the libraries to your classpath?

[Marcus Senna]

I was thinking that i was probably doing that wrong.

C:\jfreechart-1.0.4\lib\jfreechart-1.0.4.jar
I added this path to the classpath in environment variables.jfreechart-1.0.4.jar contains the folder org
