The Sparkline Chart widget displays graphs that contain metrics for an object in vRealize Operations Cloud. You can use vRealize Operations Cloud to create one or more graphs that contain metrics for objects that you add to your custom dashboards.

How the Sparkline Chart Widget and Configurations Options Work

If the metrics in the Sparkline Chart are for an object that another widget provides, the object name appears at the top right of the widget. If you select a metric when you edit the widget configuration, the widget uses the metric and its corresponding object as the source for dashboard interactions. The line in the graphs represents the average value of the selected metric for the specified time period. The boxed area in the graph represents the dynamic threshold of the metric.

Point to a graph in the Sparkline Chart widget to view the value of a metric in the form of a tool tip. You can also view the maximum and minimum values on a graph. The values are displayed as orange dots.

You can add the Sparkline Chart widget to one or more custom dashboards and configure it to display data that is important to different dashboard users. The data that appears in the widget is based on the configured options for each widget instance.

The metrics shown in sparkline widget is the current value, to view the average value you can use transformations in list views or distribution charts to calculate an average. Another way to get to an average value is to double click on the sparkline to open the metric chart, click and drag to select a range, keep the mouse button depressed and hover for a few seconds, you should see a popup that has average value.
