Real-time line charts display numeric measures for Event mashables as lines that illustrate the change in events over time. This chart also updates automatically as events occur. You add real-time charts to workspaces in Mashboard. For more information, see What are real-time charts?.
Note:
Before you can use a real-time chart, Presto administrators must create event mashables and connections to Apama and/or the Event Bus. See Use Events as Information Sources for more information.
