I have written designed GUI, on my interface there is an axes. I designed my program such that the user can plot specific points.

I want that when the user clicks on a point it should start a line and as the user is moving arround the axes, the cursor should drag the line until the user clicks on another point to end the line.

I gave to my point a button down function, when the user clicks i can get the coordinates of the point but i don't know how to get the position of the cursor and draw and interactive line. I know i have to get the current point and there's a function for that in MATLAB but I don't know how to use it. I am using R2018b.

Please for help
