Berk Can CelebisoyI believe that I am helping Java programmers by drawing their attention to a commercial quality, fully open source chart library based on the Java 2D APIs. You can download the code, run it, study it, modify it, even redistribute it under the terms of the GNU LGPL. And all you have to pay is...nothing.

Netbeans: adding to jPanel via code after init (jFreeChart)

This will be my second post. Many thanks to those who replied to my first questions.
I am using netbeans 5.5
I am attempting to run the following jFreeChart demo but in netbeans.
Original demo located here: http://www.java2s.com/Code/Java/Chart/JFreeChartPieChartDemo7.htm
Instead of programically creating the jPanel like the demo does, i would like to do it using the netbeans GUI and then add the code to create the jFreeChart.
In netbeans i create a new project, create a new jFrame and place a new jPanel on the form (keeping the variable name jPanel1) as illustrated below:
* MainForm.java
* Created on June 28, 2007, 1:48 PM
package mypkg;
import org.jfree.chart.ChartFactory;
import org.jfree.chart.ChartPanel;
import org.jfree.chart.JFreeChart;

import org.jfree.chart.plot.PiePlot3D;
import org.jfree.data.general.DefaultPieDataset;
import org.jfree.ui.ApplicationFrame;
import org.jfree.ui.RefineryUtilities;
* @author me
public class MainForm extends javax.swing.JFrame {
    /** Creates new form MainForm */
    public MainForm() {
        initComponents();
    /** Netbeans Auto-Generated Code goes here which I have omitted */
     * @param args the command line arguments
    public static void main(String args[]) {
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                new MainForm().setVisible(true);
    private void CreateChart() {
        DefaultPieDataset dataset = new DefaultPieDataset();
        dataset.setValue("Section 1", 23.3);
        dataset.setValue("Section 2", 56.5);
        dataset.setValue("Section 3", 43.3);
        dataset.setValue("Section 4", 11.1);
        JFreeChart chart3 = ChartFactory.createPieChart3D("Chart 3", dataset, false, false, false);
        PiePlot3D plot3 = (PiePlot3D) chart3.getPlot();
        plot3.setForegroundAlpha(0.6f);
        plot3.setCircular(true);
        jPanel1.add(new ChartPanel(chart3));
        jPanel1.validate();
    // Variables declaration - do not modify
    private javax.swing.JPanel jPanel1;
    // End of variables declaration
}I then attempted to call the CreateChart() function in several places (in the MainForm() function, in the pre and post creation code properties of the jPanel's properties dialog in netbeans (as well as pre and post init in the same screen)) and nothing seems to work. the program compiles and the jFrame comes up but the chart does not show.
If i run the example at the above noted link it runs fine in netbeans if i copy and paste the code directly, it just doesnt work when i try to get it to work through the netbeans GUI builder and the jPanel i create through it.
Can any more advanced netbeans/java users lend me a hand or point me in the right direction?
NOTE: in the code pasted above, i am only trying to run one of the four chart demo's listed in the original source in the link.
NOTE2: in the code pasted above it doesnt show me calling CreateChart() from anywhere, im hoping to get some advice on how to proceed from here.

Problem to print a JPanel containing jfreeChart

I need help
I am developping an application that should display and print reports with histograms.
I make the histogram with Jfreechart and put it on a JPanel. the report is a Vector of JPanel.
1. When i print only the panel containing the JFreechart, the panel is printed but the range axis label
of JFreechart is inverted.
2. When i print all the report, nothing appears on the page of the panel containing JFreechart.
here is my printing code:
//code
public int print(Graphics g, PageFormat pageFormat, int pageIndex) throws PrinterException {
if (pageIndex >= docToBePrinted.size()) {
return (NO_SUCH_PAGE);
} else {
componentToBePrinted = docToBePrinted.get(pageIndex);
//componentToBePrinted.repaint();
Dimension dim = componentToBePrinted.getSize();
double scaleX = pageFormat.getImageableWidth() / dim.width;
double scaleY = pageFormat.getImageableHeight() / dim.height;
double scale = Math.min(scaleX, scaleY);
Graphics2D g2D = (Graphics2D) g;
// g2D.translate(0, 0);
g2D.translate(pageFormat.getImageableX(), pageFormat.getImageableY());
g2D.scale(scale, scale);
g2D.setPaintMode();
disableDoubleBuffering(componentToBePrinted);
componentToBePrinted.print(g2D);
g2D.dispose();
//componentToBePrinted.printAll(g2D);
enableDoubleBuffering(componentToBePrinted);
//componentToBePrinted.
return (PAGE_EXISTS);
//end of code
"docToBePrinted" is the report
Could anyone help me please !

I have the same problem. Similarly to another entry here, be very careful about how many times you reattempt it. I did it several times, hoping it would work out a kink, and it was on an expensive order, now there are over $2000 of "temporary authorizations" depleting my available credit on my card, and it's been that way for almost a week now.
I am living overseas, and am unfortunately restricted to dial-up internet to upload this, and it either gets stuck at 64kb/8Mb or just jumps right to 8/8Mb, when there is nothing wrong with the my internet connection.
I emailed Apple in response to the order cancellation email, and stated that perhaps it was the army firewall I'm behind, asking for the site the program connects to in an attempt to unblock the site if it's inadvertently getting blocked on my end. When they replied they said it's a technical issue and that I can call Apple to talk with someone, where they will determine how much the call will cost. That's outrageous to have something brand new, and have to pay for them to help you on an issue that truly may be as simple as giving out a website.
In response to an earlier reply, I am using iPhoto 5.0.4, and I just purchased my G5 back in October. Is there a later version to iLife that I'm not finding?
If anyone finds help with this issue, I would greatly appreciate some tips!
Thanks so much,
Dave

Setting colors for item labels in JFreeChart (WaferMapRenderer)

Hi,
first of all, sorry for posting a JFreeChart related posting on this forum, but I didn't get a solution right now (I even didn't find anything useful on the JFreeChart website/forum). Here's my question...
I'm trying to set the color for item labels in the legend but with no success.
Here's a code example:
final JFreeChart chart = ChartFactory.createWaferMapChart(
    "Wafer Map Demo",         // title
    dataset,                  // wafermapdataset
    PlotOrientation.VERTICAL, // vertical = notchdown
    true,                     // legend
    true,                    // tooltips
    false
WaferMapPlot plot = (WaferMapPlot) chart.getPlot();
WaferMapRenderer renderer = new WaferMapRenderer();
renderer.setSeriesItemLabelPaint(0, Color.red);
renderer.setSeriesItemLabelPaint(1, Color.blue);
plot.setRenderer(renderer);The default behavior of the WaferMapRenderer is also strange because the item label as well as the item marker is painted black so you cannot distinguish different fields of the wafer map. Is this a bug or am I doing something wrong (or missing somehting)?
Any help would be greatly appreciated.
Thanks and best regards,
- Stephan

Your folder action script doesn't work because of one simple error:
set label index of every item of entire contents of processFolder to 7
Nowhere in your script is 'processFolder' defined, so AppleScript has no idea what you're trying to do.
Given that you (correctly) iterate through added_items, the correct format would be:
on adding folder items to this_folder after receiving added_items
repeat with item_ in added_items
tell application "Finder"
set label index of item_ to 7
end tell
end repeat
end adding folder items to
In other words, this changes the label index of each item just added.
That should work provided you're dropping files into this folder. If you're dropping folders then this would set the label index of the folder itself, but not necessarily the items within that folder. For that you'd need to add a check to see if item_ was a folder and add code to handle folders.
Also note that this kind of folder action will only work on the folder itself - that is, if you have folder A that contains subfolder B, then dropping a file into subfolder B won't trigger the script and won't change that item's label. To do that you'd have to attach your folder action to subfolder B.

ANN vCam AS3

Announcing vCam AS3 for Flash. For those of you who are
unfamiliar with vCam, I’ll give you a brief explanation. In
2005, Sham Bhangal and Dave Dixon released the original vCam or
“virtul camera” for Flash. Let’s say you are
working on an animation and you want the animation to pan from left
to right. Normally you would have to create tweens for all the
layers in your timeline. However, the vCam allows a Flash developer
to animate a single vCam instance on the timeline to create the
same pan. Simply place the vCam on left side of the stage and
create a motion tween to the right side of the stage. Publish out
your file and bam! You’ve just made your scene pan with a
single tween. Pans aren’t the only thing you could do with
vCam. You could also change it’s size and add color
transformations.
Now vCam AS3 brings a whole new list of features, including:
- Rotation
- Blur
- Brightness/Contrast
- Hue/Saturation
- and more!

Reboot the TC.. Sometimes you need to reboot the whole network.
This is what comes of Lion and then made worse in Mountain Lion of Apple not spending enough time to fix the bugs.

JFreeChart Line Chart points

Hi coders, I have implemented a line chart from the JFreeChart and have got it working nearly how i want.

     final NumberAxis rangeAxis = (NumberAxis) plot.getRangeAxis();
     rangeAxis.setStandardTickUnits(NumberAxis.createIntegerTickUnits());
     return chart;

I would try posting to the JFreeChart forum. They would probably have the best knowledge and maybe someone there may have done it before.

Questions and Answers for Ann Rosenberg for March 11 Webinar

Hello,
Please reply to this thread with any questions or discussion points related to Ann Rosenberg's Webinar on March 11, 8AM PST "Running a Successful BPM Practice for SAP Customers"
[View the announcement page|https://www.sdn.sap.com/irj/scn/wiki?path=/display/events/annRosenbergWebinar-RunningaSuccessfulBPMPracticeforSAPCustomers%252CWedsMarch11%252C11AMEastern]for more information, or to register.
About the speaker
Ann Rosenberg is Global Practice Head for Business Process Management in SAP's Business Transformation Consulting Team. Ms. Rosenberg has been with SAP since 2000, holds a Black Belt in Six Sigma, and an executive MBA from SIMI. She has extensive experience in setting up BPM competency centers, and helping IT departments execute transformational change to support process-oriented organizations. Ms. Rosenberg recently published the book Business Process Management - The SAP Roadmap.

Hi Ashish,
There are several options for you. With the process list that is part of the Process Desk, you can display all running, completed, and canceled processes that are relevant for you. [Displaying Processes in the Process List|http://help.sap.com/saphelp_nwce711/helpdata/en/d1/6d5ee426da4a84951c5acad77a1911/content.htm ]
In addition, with SAP NetWeaver Administrator, if you have administrative rights to a process you can find out if the process completed successfully or not, who executed tasks in the process, what is the data in the process context, etc. [Managing Processes and Tasks with SAP NetWeaver Administrator|http://help.sap.com/saphelp_nwce711/helpdata/en/58/c325d5323b447ebb9d020c7fbaa5be/content.htm]
Currently there is not a public API for accessing the native process metadata, but this will come with wave 2. However, if you have important process metrics that you would like to track today, you can always add an automated activity to your process model that posts process data to a web service.
Kind regards,
Michael

Date/Time on X-Axis with JFreeChart

Hi guys,
I've asked this question on the JFreeChart forums, but got no response.
If anyone has any experience with JFreeChart, help would be most appreaciated.
I am drawing a XY Line Chart to display CPU usage retrieved from a database. The user can search with specific dates/times (eg: from: 24/2/2005 to: 16/4/2005) - and then these results would be graphed.
My question is, how do I use dates/times on the X-axis using JFreeChart?
The results I am getting from the DB would be a time-stamp and CPU usage.
Here is my current code, but it wont work with a time-stamp:
public static class ChartTest   {
    public ChartTest()
        // create a dataset...FOR LOOP
        XYSeries dataSet = new XYSeries("CPU Usage");
        TimeSeries closing = new TimeSeries( "Closing Value", Day.class );
     for(int h=0; h < newArray[0].length; h++)
        for(int i=0; i < newArray.length; i++)
           dataSet.add(newArray[i][h], newArray[i][h++]);
        XYDataset xyDataset = new XYSeriesCollection(dataSet);
        // create a chart...
        JFreeChart lineGraph = ChartFactory.createXYLineChart
                    ("Mitch's CPU Usage Test", // Title
                      "Time",           // X-Axis label
                      "CPU Load",           // Y-Axis label
                      xyDataset,          // Dataset
                      PlotOrientation.VERTICAL,        //Plot orientation
                      true,                //show legend
                      true,                // Show tooltips
                      false               //url show
        // create and display a frame...
        ChartFrame frame = new ChartFrame("CPU Usage Test", lineGraph);
        frame.pack();
        frame.setVisible(true);
    }
