This time I'd like to introduce a simple bar-graph poll. The
database has one radio field with the choices. It is set to required entries: 1, Entries required before viewing:1, Maximum entries:1, so that the user/student has to vote before viewing the results. The single view is effectively disabled by redirecting the page to the list view. The list view displays a bar-graph of the results. I'd like to make the code just a little bit more generic and then I'll add the preset to
Moodle Exchange. In the meantime see image below and comments and suggestions are welcome.
Other things you can do with a database if you only find a good enough reason to do them:
