Notice in the lower left hand corner the "Plot X" , Span # etc. This allows you to put in the Span # and X dist and the Shear, Moment and Deflection will be shown in the Boxes to the right and if you click the "Plot X" button it will plot the values on the graphs. You can actually put your mouse and tag anywhere on the diagrams and the values will be automatically put in also, as i did in this example of 1.67 feet left on span 1..
