Changing arc gap

This task applies to Gauge charts.

By default, the gap between the measurement (inner) and qualitative (outer) arcs is 5 pixels. To change it, navigate to the Marks menu, and select a new value for the Arc Gap option.

Note how adjusting this setting changes the appearance of the visual. The outer (qualitative) arc is fixed, while the inner (measurement) arc radius changes to accommodate the arc gap setting. When this setting is at 0, a gap does not appear.
