Adding drawing area to null layout GUI

Question

I have been working on a GUI for some time, I am required to plot my results in a scatter diagram, the problem is is that I need to create a drawing section to place the results of the GUI on.

What would be the best way to do this ?.

Is there an easier way to go about it while still using null layout ?

Thanks

There is no reason you need to use a null layout. Use a proper combination of layout managers and you won't have a problem. — camickr, Nov 19 '11 at 23:15

try to put everything into a JPanel and set a layout for that (i.e. a BoxLayout). then you add your diagram JPanel to the main JPanel.

+1 For an example of using a `BoxLayout` to center a component, see the 2nd linked code in my answer. – Andrew Thompson Nov 20 '11 at 05:31

Centering a component can be achieved easily using GridBagLayout (one of the few tasks for which I would use GBL). See the code for adding the image in the bottom right of this GUI for details¹.

OK, I'll admit, the 'short answer' is:

Add a component as the only component in a GridBagLayout with no constraint & it will be centered. Put the panel using GBL into a JScrollPane, and the job is done.

For a closer look at centering components using different layouts, see this example.

In addition to the layout suggestions, you might find some ideas in this series of scatter plots that rely on jfreechart.
