Collate PlotWindows into a stack

[Mike Myerburg]

Hi-

My plugin generates numerous plotWindows that eventually take over the
screen.  Is there an easy way to have each new plotWindow placed into a
stack?

I figure that would keep it nice and clean, but have been struggling on
writing the java to make this happen.

Thanks, Mike

PlotWindow is an extended ImageWindow, thus you can call
getImagePlus().getProcessor() on it. So to make a stack:


PlotWindow[] pw = ....

ImageProcessor ip = pw[0].getImagePlus().getProcessor();
int w = ip.getWidth();
int h = ip.getHeight();

ImageStack stack = new ImageStack(w, h);
stack.addSlice("plotwindow 1", ip); // the first one

// start at the second one, index 1
for (int i=1; i<pw.length; i++) {
    stack.addSlice("plotwindow" + (i+1),
pw[i].getImagePlus().getProcessor());
}


new ImagePlus("All PlotWindows", stack).show();

Thank you for the help.  However, I dont think this way will work for
me, because the plots are not generated all at once.  The following
class is in the plugin and is used to plot the results.  As I use the
plugin multiple times I wind up with numerous "PSD Sum" windows, but
they are not all generated at one time.

public void PSDPlot(float[] PSD){
        float[] frequency = new float[PSD.length];
        for (int i=0; i<frequency.length; i++) frequency[i] =
frequency(i,frequency.length);
               
        PlotWindow psdSumPlot = new PlotWindow("PSD Sum","CBF","PSD",
frequency, PSD);
        psdSumPlot.draw();
        }

I am pretty new with java and have been hacking my way through...  I
appreciate the help, Mike

You have then several options.

1) reshape your code so that you can capture them

or:

2) scan WindowManager for windows that are instances of PlotWindow. For
example:


int[] ids = WindowManager.getIDList();
for (int i=0; i<ids.length; i++) {
    ImagePlus imp = WindowManager.getImage(ids[i]);
    if (imp.getWindow() instanceof PlotWindow) {
       // Add this window to the list of PlotWindow to put into a stack
       // ...
   }
}


Ideally you'd run this when done generating all.

Thanks for the suggestions- I think that I am getting closer.  I added
this to the routine and created a static psdStack.
               
        ImageProcessor ip = psdSumPlot.getImagePlus().getProcessor();
        if (psdStack.getSize() == 0) {
                psdStack.addSlice("plotwindow 1", ip); // the first one
                new ImagePlus("All PlotWindows", psdStack).show();
        } else psdStack.addSlice("plotwindow 1", ip);

The first image gets placed in the stack and when it runs the next time
nothing happens.  I assume that the slice is added, but the ImagePlus is
not refreshed.  Is there a way to make the ImagePlus update itself?

Thanks, Mike
