Specifying qualitative range as percentages
The Gauge and Bullet visuals use the Qualitative Ranges shelf to define the fit of the main value (on the Measure shelf) relative the value specified by the Compare To shelf. An alternate approach is to specify these ranges as percentages.
The visual on the left shows the ranges when they are explicitly defined as scalar values 600, 700, and 800. The visual on the right shows the qualitative ranges as percentages: 60%, 80%, and 100%.
