Adding Callbacks to a Plot

(Originally posted on Doug's MATLAB Video Tutorials blog.)

This eleven minute video shows how you can make plots on two axes such that when one point of a pair is clicked, they both are highlighted. In this video you will see:

• LINE used instead of PLOT so that each data point has its own handle
• Debugging when a nested function is not closed properly
• Debugging when inputs are unspecified to a callback
• Handle graphics manipulation of marker size
• Lining up code for better readability
• Frequent testing of code to minimize errors when they do occur
