Hello
I'm working on a GUI, where I inserted a "pushbutton" that draws points on a "axes". then insert a second, "pushbutton" to insert lines with "getline" function. The lines are positioned on the points. I wonder how can I when inserting lines the coordinates [x, y] match. for example, when you click to draw the line the selected location will be exactly the position of the points.
I need to store the coordinates of the points when I'm drawing the lines
Thank you very much in advance
