David, To capture points on a graph: 1) Left click on the graph to select it. 2) Hold down Ctrl and put the cursor over the point you want. 3) Left click on the point. 4) Use Copy (From the menu, or use Ctrl-C, or right click and select Copy) 5) Then paste the resulting coordinates into your expression. If you click off a series of points, then Copy will give you a list of the points.
