How to disable zoom by mouse dragged without disabling by mousewheellistener in jfreechart?

I would like to disable zooming by mouse dragging(which paints that rectangle), but not disable zooming by MouseWheel. I found in another topic how to disable zoom reset while dragging mouse to left (restoreAutoBounds) and I'm interested in how to solve this problem. Is there a little shortcut to do that?

Solution

  • Ok, I've done it, by overriding MouseWheelListener. After chartPannel.setMouseZoomable(false).:

    chartPanel.addMouseWheelListener(new MouseWheelListener() {
        public void mouseWheelMoved(MouseWheelEvent arg0) {
            if (arg0.getWheelRotation() > 0) {
                chartPanel.zoomOutDomain(0.5, 0.5);
            } else if (arg0.getWheelRotation() < 0) {
                chartPanel.zoomInDomain(1.5, 1.5);
            }
        }
    });

    zoom(In/Out)Domain, because I wanted to rescale only domain axis.
