A pie visualisation shows how individual pieces of data relate to the whole using a circle to represent the whole.
A Donut visualization shows how individual pieces of data relate to the whole using a donut shape to represent the whole.
Single score visualisations display a single, key business value or current aggregate indicator score. You can set a score to update in real-time.
The following enhancements are made to pie, donut, and single score visualisations in the Quebec release:
* The metric label name is displayed near the metric value.
* Legend percentages are shown along with values.
* Data labels are shown as only percentages, as values, or as both.
Gradient, texture, or no colour are not valid colour options for data display.
You can set 'default', 'colour palette' and 'fixed element colour' for pie and donut visualisations, and 'default' and 'single colour' for single score visualisations.
