TimeSeries bug in version 0.9.4......?????

[reji]

Hi,

Today I have downloaded and updated JFreeChart 0.9.2 to 0.9.4. But while creating a "TimeSeriesChart with 'null' XYDataset" I am getting the following exception....


It was working fine with version 0.9.2


Exception occurred during event dispatching:
java.lang.NoSuchMethodError
at com.jrefinery.chart.JFreeChartInfo.<init>(Unknown Source)
at com.jrefinery.chart.JFreeChart.<clinit>(Unknown Source)
at com.jrefinery.chart.ChartFactory.createTimeSeriesChart(Unknown Source )

My chart creation statement is as follows.

logChart = ChartFactory.createTimeSeriesChart("", "", "", null, false);


Any idea how to come out this problem?

Thanks,

reji

I am having 9 TimeSeriesChart components in a single panel and it is not possible to create the XYDataset for every chart while loading the panel....

Hi Reji,

I'm having trouble reproducing the problem, can you put together a small sample app that shows the problem.

Hi David,

This is my test code and the result...

------------------------------------------------------------------------------------------------

import java.awt.*;
import javax.swing.*;
import com.jrefinery.chart.JFreeChart;
import com.jrefinery.chart.ChartFactory;
import com.jrefinery.chart.ChartPanel;


public class TimeDemo
{


public TimeDemo()
{


JFreeChart chart = ChartFactory.createTimeSeriesChart("", "", "",null, false);

ChartPanel chartPanel = new ChartPanel(chart);

chartPanel.setPreferredSize(new Dimension(500, 270));


JFrame frame = new JFrame();

frame.getContentPane().add(chartPanel);


frame.setVisible(true);

frame.pack();
}

public static void main(String[] args)
{

new TimeDemo();

}

}
------------------------------------------------------------------------------------------------
run time result

Hi Reji,

The demo runs fine for me (displays a chart with no data), no exceptions.

My guess is that you have the previous version of JCommon on your classpath still...can you check that? It needs to be 0.7.1.
