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:
