(v24) Bars: Histograms

Bars: Histograms

This applies to: Visual Data Discovery

Histograms require only one metric (number). The metric data range is divided into intervals and the metric values that fall within each interval are counted. The histogram plots the value counts (Volume) against the metric intervals.

Histograms are supported only by data sources that use connectors that support the calculations necessary for histogram visuals with integer values.

Support for this feature by connector is shown in the following table.
