Drawing Rotated Text

 // Draw string rotated clockwise 90 degrees.
 AffineTransform at = new AffineTransform();
 at.setToRotation(Math.PI/2.0);
 g2d.setTransform(at);
 g2d.drawString("aString", x, y);
     
 // Draw string rotated counter-clockwise 90 degrees.
 at = new AffineTransform();
 at.setToRotation(-Math.PI/2.0);
 g2d.setTransform(at);
 g2d.drawString("aString", x, y);
