Usage

From source file:SineDraw.java

public void paintComponent(Graphics g) {
    super.paintComponent(g);
    int maxWidth = getWidth();
    double hstep = (double) maxWidth / (double) points;
    int maxHeight = getHeight();
    pts = new int[points];
    for (int i = 0; i < points; i++)
        pts[i] = (int) (sines[i] * maxHeight / 2 * .95 + maxHeight / 2);
    g.setColor(Color.RED);
    for (int i = 1; i < points; i++) {
        int x1 = (int) ((i - 1) * hstep);
        int x2 = (int) (i * hstep);
        int y1 = pts[i - 1];
        int y2 = pts[i];
        g.drawLine(x1, y1, x2, y2);/*from  w  w w  .  j a v a  2  s  .  c om*/
