You will need to have some buttons to do the add and delete, and the easiest way to point to something on a graph is to use a graph cursor. Rather than just clicking on the graph, you grab the cursor and drop it on the graph where you want to affect. You can have the cursor free, snapping to any plot, or locked to a single plot. The cursor display also has numeric displays you can type into. I believe some VIs were written to map between a pixel point and the graph scales values, but I'm not sure how thorough this VI is or where it it located. Greg McKaskle
