SCALE CONTROLS

Above the examiner window is a thumb wheel and an editable text
       box which allow the user to apply a multiplier to all values
       represented in the scene.  Spinning the wheel to the right and/or
       increasing the text value for the scale will increase the height
       of the bars.  Spinning the wheel to the left and/or lowering the
       text value will decrease the height of the bars.  The button to
       the right of the thumb wheel will reset the scale so that the
       bars appear at the original height for their current value.
