Plot Chart on Jpanel.

[cowboy]

Hello everyone! i want to create and plot my Jfreechart on Panel that placed on main form..I use this code

  JFrame jfrm;
        XYPlot plot;

        jfrm = new JFrame();
        Toolkit tk = Toolkit.getDefaultToolkit();
        int xSize = ((int) tk.getScreenSize().getWidth());
        int ySize = ((int) tk.getScreenSize().getHeight());
        jfrm.setSize(xSize, ySize);
        jfrm.setVisible(true);
        jfrm.setResizable(true);


        XYSeries s1 = new XYSeries("IV");
        double min=1000000;
        double max=0;


  try {
     connection = DriverManager.getConnection("jdbc:mysql://localhost/mysql","root", "");
     statement = connection.createStatement();
     ResultSet rs=statement.executeQuery(createDatabaseQyery);

     while (rs.next()){
     
     String str =rs.getString("price");
     Float f = new Float(str);
     double x = f.doubleValue();

     String t=rs.getString("time");
     DateFormat sdf = new SimpleDateFormat("hh:mm:ss");

               try{
                java.util.Date y = sdf.parse(t);
                calendar.setTime(y);
                String time=Integer.toString(calendar.get(Calendar.HOUR_OF_DAY))+":"+Integer.toString(calendar.get(Calendar.MINUTE))+":"+Integer.toString(calendar.get(Calendar.SECOND));
              
               }
                catch (Exception e){
             e.printStackTrace();
             }

            s1.add(i,x);

            i=i+1;
            if (min>x) min=x;
            if (max<x) max=x;

     }

     }
     catch (Exception e)
     {
     e.printStackTrace();
     }
  finally {
if (statement != null) {
try {
statement.close();
}
catch (SQLException e)
{
e.printStackTrace();
}
}
if (connection!= null) {
try {
connection.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
}


        XYDataset xyDataset = new XYSeriesCollection(s1);
       


        JFreeChart chart = ChartFactory.createXYLineChart("IV", "", "", xyDataset,PlotOrientation.VERTICAL, false, false, false);
 

        final ChartPanel chartPanel = new ChartPanel(chart);
    //   jfrm.add(chartPanel);
        jPanel4.add(chartPanel);

       chart.getXYPlot().getRangeAxis().setLowerBound(min-2);
       chart.getXYPlot().getRangeAxis().setUpperBound(max+2);

But i see nothing on jPanel.. But then i plot my chat on JFRM(dinamical created FRAME ) the chart appear on them..Where is a problem?

[Fubarable]

Where in your code are you adding the JPanel to a root container and displaying it? In other words, I don't see where you've added your JPanel to a JFrame.

[cowboy]

no..I using a Netbeand. Ive created a form and drop on this from Jpanel4.

[cowboy]

Is it possible to plot a chart on a Panel that dropped on maim form?

Is it possible to plot a chart on a Panel that dropped on maim form?

What does your fine manual say about it?

kind regards,

Jos

[cowboy]

tell me please or just give me a link for this

[Fubarable]

For me at least, it's hard to give a recommendation without knowing exactly what your problem is, and it's going to be your job to find this out. I'm not even sure, if you are asking a Netbeans question or Java question? My suggestion would be to get this working in a non-netbeans-generated very simple Swing app first. Divide and conquer in order to debug your problem.

I create project using Netbeabs IDE. May be my English language are so worst :( ?
I ll show you a printscreen :

This is a printscreen of my main form in neatBeans.Purple scope-it is a jPanel4. i just want to plot my chart on them and i wrote this for that

jPanel4.add(chartPanel);

But it does not..
And this is another printscreen


In this case i just plot my chart on dinamically created frame

jfrm.add(chartPanel);

Help me please

What layout does your jPanel4 use? Have you tried setting its layout to BorderLayout and adding your chartPanel to it BorderLayout.CENTER?

[cowboy]

Can you give some example how i can done this?

[Fubarable]

I can give you plenty of examples of how to do this without NetBeans, the best is here: Laying out components within a container.

But to do it in NetBeans, you'll likely have to right click on the JPanel, inspect its properties and set its layout property to BorderLayout. If you don't understand this, then please look at your NetBeans help files for more.

But again, I suggest that you learn to code this without NetBeans code-generation and only use NetBeans code after you have a basic understanding of Swing coding. The tutorial linked above has all you need to learn how to code Swing.

[cowboy]

Thanks, i ll try to create some app without netbeans..

From Russia with love, ofcose :)

[cowboy]

Thank to all but i should to add this string in my code

jPanel4.add(chartPanel,BorderLayout.EAST);

And set the appropiate Layout to Jpanel in Net beans..
And to all.In Java Guide wrote that it is highly recommended to use a IDE instead codding by the hand for more convinience.
