One of the features of the Explorer in the BI Toolbox portlet is to display data in a
circle chart, such as a pie or donut chart, instead of a bar chart.
Repeat Steps 1-3 above to display the circle chart in the portlet.
Hover over a section of the chart to display a pop-up with additional
information.
(Optional) Hover over the top right border of the circle chart until the drill
icon displays, and click it to display the Explorer.
Click on a section to display a Drill to prompt, which allows you to
change the filters used to create the chart.
To remove any filter changes, close the portlet, add a new BI Tool
portlet, and re-select the dashboard visualization.
Click the icon of an image with a downward pointing arrow to export the
current display of the chart as an image.
