Hi
I tried to check it out this example you sent me. I have got an additional question:
I tried to implement the method: addButton(snapShotButton); From the google I got:
button.setPreferredSize(BUTTON_SIZE, BUTTON_SIZE);
add(button);
}
So I added it, but I could not implement "add(button)" ; I imported a lot of nebula...
So I send the code snippet concerning this problem. Where is "add(button)" defined ???
Here the code:

Hi Lars,
You can create the plot with a toolbar. The toolbar has export button. The sample code is in:
http://git.eclipse.org/c/nebula/org.eclipse.nebula.git/plain/examples/org.eclipse.nebula.snippets/src/org/eclipse/nebula/snippets/visualization/SimpleToolbarArmedXYGraphExample.java
The relatived code in org.eclipse.nebula.visualization.xygraph.figures.XYGraphToolbar.java is:private void addSnapshotButton() { Button snapShotButton = new Button(XYGraphMediaFactory.getInstance().getImage("images/camera.png")); snapShotButton.setToolTip(new Label("Save Snapshot to PNG file")); addButton(snapShotButton); snapShotButton.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent event) { // Have valid name, so get image ImageLoader loader = new ImageLoader(); Image image = xyGraph.getImage(); loader.data = "" ImageData[] { image.getImageData() }; image.dispose(); // Prompt for file name String path = SingleSourceHelper2.getImageSavePath(); if (path == null || path.length() <= 0) return; // Assert *.png at end of file name if (!path.toLowerCase().endsWith(".png")) path = path + ".png"; // Save loader.save(path, SWT.IMAGE_PNG); } }); }
Best regards,
Trig

Hellobelow is the code! It is easy, it just gives a simple plot. How can I save this plot (xygraph) asa bmp or jpg-file on the PC ? I posted the question on several forums, either the answer is toocomplicated or the problem is too trivial for the community.A hint would be very helpful!thanks!package org.eclipse.nebula.visualization.xygraph.examples;
