With this kind of question, you need to show us what you have tried, and then ask specific questions about which part of the program is giving you trouble. Here's a hint: You will need at least 5 functions: One to make the figure and axes (graph) to draw in, One to start drawing when the mouse is clicked,,one to keep drawing when the mouse is moved, one to stop drawing when the mouse is released, and one to save the x/y coordinates to the text file.
