point data

[Nobody/Anonymous]

Is there a way to get the point infomation that is displayed when you click the view coordinates button, but is triggered by another event such as a mouse double click?  What I really want to know is how do you get a point's coordinates from clicking that point.

I suggest you to take the sources of jmathplot and modify it as follows in mouseClicked method in PlotPanel.java :

    public void mouseClicked(MouseEvent e) {
        mouseCurent[0] = e.getX();
        mouseCurent[1] = e.getY();
        e.consume();
        mouseClick[0] = mouseCurent[0];
        mouseClick[1] = mouseCurent[1];
////////////////HERE THE CODE ADDED////////////////////////

        for (int i = 0; i < plots.size(); i++) {
            RelativeCoord[] coords = getPlot(i).getCoords();
            for (int j = 0; j < coords.length; j++)
                System.out.println(coords[i]); //change here
        }
////////////////////////////////////////
        int[] origin;
        double[] ratio;
        switch (ActionMode) {
        case ZOOM:
            if (e.getModifiers() == 16) {
                origin = new int[] { (int) (mouseCurent[0] - panelSize[0] / 4),
                        (int) (mouseCurent[1] - panelSize[1] / 4) };
                ratio = new double[] { 0.5, 0.5 };
            } else {
                origin = new int[] { (int) (mouseCurent[0] - panelSize[0]),
                        (int) (mouseCurent[1] - panelSize[1]) };
                ratio = new double[] { 2, 2 };
            }
            base.dilate(origin, ratio);
            break;
        }
        repaint();
    }
