Usage

From source file:net.sourceforge.processdash.ui.lib.chart.StandardDiscItemRenderer.java

protected void drawDiscLabel(Graphics2D g2, Ellipse2D shape, Paint labelPaint, Font labelFont, String label) {
    g2.setFont(labelFont);//from   w ww.j ava  2  s.co m
    g2.setPaint(labelPaint);
    FontMetrics m = g2.getFontMetrics();
    int height = m.getAscent();
    double halfHeight = height / 2.0;

    double radius = shape.getWidth() / 2;
    double availableRadius = radius - getLabelPadding();
    double halfWidth = Math.sqrt(availableRadius * availableRadius - halfHeight * halfHeight);

    int width = (int) Math.floor(halfWidth * 2 + 0.99);

    Rectangle viewR = new Rectangle(width, height);
    Rectangle iconR = new Rectangle();
    Rectangle textR = new Rectangle();
    String text = SwingUtilities.layoutCompoundLabel(m, label, null, SwingConstants.CENTER,
            SwingConstants.CENTER, SwingConstants.CENTER, SwingConstants.TRAILING, viewR, iconR, textR, 0);
    if (text.equals(label) || text.length() >= 3 + minLabelChars) {
        double x = shape.getCenterX() - halfWidth + textR.x;
        double y = shape.getCenterY() + halfHeight + textR.y;
        g2.drawString(text, (float) x, (float) y);
    }
