The Magic Quadrants widget allows you to plot performance across two metrics at the same time.
How does it work?
The widget can report on overall, section, and question scores. You would want to pick two score metrics, place the crosshairs at the scores that are considered "acceptable" and set the Heat Mapping levels to show which locations are doing well (green) or doing poorly (red) in both metrics.
Drilldown functionality
Clicking on a bubble will open an "Evaluations" pop up window, showing you a list of evaluations that match the bubble's filtering.
Using the left PC icon will open the evaluation in a new tab of your browser, while using the right PDF icon will create a PDF of that evaluation.
Other settings
Remember to check a different help article detailing most of other settings of this widget.
