Bars: Histogram Charts

Histograms require only one metric (number or integer). 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 Zoomdata connectors that support the Histogram feature. See Connector Feature Support.

Data from Fusion data sources can be used in histograms.

To configure default histogram settings for a data source configuration:

  1. Edit the appropriate data source configuration. See Editing a Data Source Configuration.

  2. Select the Charts tab in the data source configuration wizard.

  3. On the Standard subtab of the Charts tab, select Bars: Histogram.

    If you want to be able to display the data collected by this data source configuration as a histogram, make sure the Bars:Histogram checkbox is selected.

    Default histogram settings appear on the right side of the page.

  4. Configure the default settings as follows:
