I would like to be able to draw a line on the graph and see the dollar value of the starting point, the dollar value of the end point, and the price increase and percentage price increase. This benefits in two ways: (1) So I can easily pick between two stocks which has the stronger up-move, and (2) If I want to see where the stocks price is at a certain profit target I can draw the line and see both where 15% profit is and know that is at $40.00 (example). See attached file for the example.
