The Bar Chart allows you to visually represent metric levels across multiple instances. Like most widgets, you can scope the results to specific instances and metrics using a variety of filtering options. Select whether to show live metric values or aggregates over a certain period. Also, you have options for controlling the X-axis legend and the orientation of the chart.
