front panel graph with selectable points

[archangel_hp]

I don't if this can be done, but I was wondering if I can have a graph in the front panel that would graph only the points I select. This is the situation: I'm taking measurements in the program and I want to make a graph with them. The thing is that a don't want a graph with lots of points, I just want to select a point and graph it. When I want to, I select to take a point and graph it, then I'll change the independent variable and then select again one point and graph it, showing a curve of what I have, and so on. I know that for this maybe I'll need to store those single points with an array or something. If anyone can help me, please do so. Thank you.

The data you acquire is received in array form and based on the sample size, you should be able to determine the number of points in the array.  Then simply decide which points you want and put them into a second array and plot that array.
