I have a plot of an oscillating and decaying sinusoidal wave. I need to find the peaks and valleys using the data tips, then extract the x and y coordinates of each of them so that I can do some further math. I first turned datacursormode on, then clicked each peak and valley. If I hit "extract current data tip to workspace", it seems to extract all data tips, and into a struct. I eventually figured out how to get it to display the coordinates (var.position) which then shows every 2 x 1 array of coordinates, separately but not labelled (probably because none of the data tips had any sort of label or name) and seemingly in a random order. But I cannot access the numbers I need. My next step would want to be to create vectors for each of x and y, because I do know how to access individual elements of a vector. But I have been given instructions to specifically use the datatips to get the coordinates, and it doesn't sound like I can just write down the numbers that the datatips show while on the graph. So how do I get what I need?
