Use the Ruler Log Scale Function

The log scale function changes the axis based on orders of magnitude of the metric selected for that axis. A log scale is nonlinear and best used when there is a large range in quantity. Log scales can only be used for positive values. Negative values are displayed as ‘1’ in the metric axis. In addition, when this option is selected, the Auto option is enabled for Min, Max, and Step.

The scale is built for whole the data range.

To enable the log scale function for the visual, select the Log Scale checkbox to enable. To disable, clear the checkbox.

The Log Scale function is not available for arc gauges. Arc gauges use the Rulers sidebar to control some different settings than are used by most visuals. See Arc Gauges.
