The second method: move the mouse pointer over the vertical scale until the pointer icon becomes as shown in the figure. The pointer should be placed in the top or bottom parts of the scale, at approximately 10% of the scale height from the top or bottom of the scale. Left click and drag away from the scale center to enlarge the scale, or toward the scale center to reduce the scale.
