Panel: Bar Chart

Overview

This panel allows users to visualize data over time windows as columns (vertical) or bars (horizontal). Data is aggregated using one of the following calculations: average, minimum, maximum, sum, or a count of times received. Overall time range and time window duration are both customizable. Up to 5 signals can be visualized simultaneously.

The chart loads data when the dashboard loads but does not automatically refresh. A refresh button is provided for the user to refresh the chart.
