Practical Example: Adding callbacks to a plot

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

Also note, I have made a direct link the the Lazy Web open challenges page. There is a new challenge up. Don’t forget there are t-shirts for answering the one minute survey below.
