Every displayed graph represents a Collector which is responsible for retrieving values. In this example we add multiple predefined collectors to the monitor. The last added collector will be displayed topmost. The default callback delay for a collector is 500ms. In this example the callback rate varies from 500ms to 1000ms.

The #addCaption method allows you to display a caption including exact values for every graph. The popupOnly param specifies if the caption should only appear within the MonitorPopup-ToolTip which will be enabled by calling #setPopupEnabled. You can enable/disable the visibility of every graph by the context menu.

All relevant lines are highlighted. Press the "Run..." button to start the example.
