Zoom Number Interaction

The Graphing Zoom Number Line Interaction is not one of the Portable Custom Interactions in the standard TAO package. It will need to be installed in a separate extension.

A Graphing Zoom Number Line interaction is useful if you would like the Test-taker to provide a visual answer as a decimal value by selecting it on a graduated line. A zoom is available to help the test-taker  select a precise value.

If you wish to use the Graphing Zoom Number Line interaction, the corresponding extension will need to be installed first. See the chapter on the Extensions Manager for information on how to do this, or ask your systems administrator about the installation of this extension.
