Ok, I've defined my plan for the time being:
1- get hold of a field image
	do a snap, get its image.
	Working!

2- get hold of a ROI set
	via mm.displays().getCurrentWindow().getImagePlus().getRoi()
	Also working! (I even check that the ROI is actually defined)

3- get intensities of acquisition images and plot them

Here, I was hoping to be informed using DataProviderHasNewImageEvent.
But my first try did not work.

I'm doing:

      // Run an acquisition using the current MDA parameters.
      acquireButton_ = new JButton("Run Acquisition");
      acquireButton_.addActionListener(new ActionListener() {
         @Override
         public void actionPerformed(ActionEvent e) {
            // All GUI event handlers are invoked on the EDT (Event Dispatch
            // Thread). Acquisitions are not allowed to be started from the
            // EDT. Therefore we must make a new thread to run this.
            Thread acqThread = new Thread(new Runnable() {
               @Override
               public void run() {
                  ds_ = studio_.acquisitions().runAcquisition();
                  ds_.registerForEvents(me);
               }
            });
            acqThread.start();
         }
      });

where "me" is a reference to the Frame instance, and there:

   @Subscribe
   public void onNewImage(DataProviderHasNewImageEvent event) {
	   imagesReceived_++;
	   title.setText("We have an image to work with!");
   }

I'm not getting along this bus thing.
Help ?
