Getting a JFreeChart inside a specific JPanel

[Terry Flint]

Hi java people! I've really been having a hard time getting my head around this. First of all, I have this class which builds a GUI, which is pretty much exactly the layout I want.

import java.util.ArrayList; 
import java.util.Collections;
import java.util.HashSet;

import java.awt.GridBagConstraints;

import java.awt.event.ActionListener;

Okay, now run it. You see that large JPanel on the left. I want to get a chart of some description to take up that space. I've been using JFreeChart, and I'm more or less used to making them at this point, but they always open in their own screen when I try and combine them with the above class. Since I haven't really decided what type of chart needs to go in there yet, here is a sample one from the JFreeChart people themselves, which i was using to get some grasp of how to manipulate charts inside a panel:

        desktopPane.setPreferredSize(new Dimension(600, 400));
        final JInternalFrame frame1 = createFrame1();
        desktopPane.add(frame1);
        frame1.pack();

So, given this example, how would I get the charts from the second class at the location I want in the first class?

Since it is a JComponent, just add the ChartPanel you have created on line 64 of InternalFrameDemo as a child to the JPanel !

[Terry Flint]

Okay, this is probably a stupid thing to ask, but I'm fairly new. When you say "child" does that mean the same thing as it does when talking about inheritance?

No !!! You have a JPanel so just use it's add() method to add the ChartPanel to it. Frequently one can just use the ChartPanel instad of the JPanel so where in your code you add the JPanel your may be able to just add the ChartPanel.

[Terry Flint]

So this portion of the Statistics class should look something like this?

//Graphing Panel  

    JPanel graphingPanel = new JPanel();  
    constraints.anchor = GridBagConstraints.SOUTHWEST;  
    constraints.insets = new Insets(0,0,5,5);  
    constraints.fill = GridBagConstraints.BOTH;  
    addComponent(graphingPanel,6,1,8,11);  
    graphingPanel.add(chartPanel);

    addComponent(graphingPanel,6,1,8,11);  
    graphingPanel.add(chartPanel);

Try it ! Or use the chartPanel in the addComponent() then you don't need the graphingPanel .

[Terry Flint]

Okay, I actually thought this would be easy to figure out, since it sounds like it should be simple. I have no idea how to get this line to be read by the statistics class.

        final ChartPanel chartPanel = new ChartPanel(chart);  

My usual instinct would be to create a getter for chartPanel , but since it is already inside the createFrame1 method, that won't work. I also tried making the createFrame1 method public and returning chartPanel instead of the frame itself, but that just causes a compile error. I'm sure I'm missing something obvious, but I just can't see it.

[Richard Tookey]

Don't try to cobble together the two disjoint bits of code. Extract the few lines of code that create the ChartPanel from the JFreeChart example and insert them into the method that creates the graphing panel. You can then discard the rest of the JFreeChart example code. You will need to write your own code to populate the JFreeChart model but for test purposes you can just copy the example createDataset() method into your class. Later you can modify the createDataset() method so it populates the chart with your own data.

[Terry Flint]

I actually just managed to get what I wanted, but I did cobble the code together a bit. I will try and do it the way you just recommended though. For the sake of those that may be having problems with this in the future, I'll post the solution when I manage to do it the correct way. For now, I'm considering this problem to be resolved.

[Terry Flint]

I believe this is a more acceptable version than what I had before.
