Dashboard Nodes

the flows dashboard palette includes nodes, which when dragged onto a canvas, become widgets in a dashboard these nodes enable you to build a dashboard with common elements, such as buttons, drop down lists, and charts when you combine these nodes with data collection flows, you can monitor sensor data in a single view add dashboard nodes to the canvas you can add dashboard nodes to the canvas in an existing flow the process of adding dashboard nodes will be demonstrated by way of an example example add dashboard nodes to the canvas for this example, a button, text, gauge, and chart are added to the first group a dropdown is added to the second group note when you add dashboard nodes to another existing flow, the nodes are added to the layout under the first group you can select which group the node belongs to from the edit \<groupname> node dialog box caution adding the same node to another flow in the same flow view adopts the same configuration to add dashboard nodes to the canvas from the navigation panel, select flows manager click the expand icon next to a selected flow the flow opens in a new tab click the menu icon, select view > dashboard , and then drag the sidebar up from the bottom of the canvas from an existing flow tab in the flow view, drag the following nodes to the canvas button text gauge chart dropdown the nodes appear on the canvas double click one of the added dashboard nodes enter a name for the node in the name field, and then click done repeat steps 5 6 as needed, entering names for all the dashboard nodes on the canvas double click the dropdown node select the second group from the group drop down list, and then click done if necessary, choose the add new dashboard group option and create a second dashboard group and then add the dropdown node to this newly created group click deploy configure a dashboard node you can configure a node you have added to the canvas each node allows for the configuration of various options when you add a dashboard node to the canvas, you must double click it to configure its settings most of the dashboard nodes must be assigned to a dashboard group caution adding the same node to another flow in the same flow view adopts the same configuration example dashboard node configuration for this example, a dashboard switch node is configured to configure a switch node from the navigation panel, select flows manager click the expand icon next to a selected flow click the menu icon, select view > dashboard , and then drag the sidebar up from the bottom of the canvas from an existing flow tab in the flow view, drag a switch node from the dashboard category to the canvas double click the switch node the edit switch node dialog box appears configure all fields as desired click done on the top right corner of the edit switch node dialog box click deploy customize message text colors you can customize the message text colors there may be times when you want to assign colors to displayed messages, particularly when monitoring device status the following example illustrates how to configure a flow and dashboard to change the message color based on the device status ready, rebooting, warning, or error for your convenience, the following code can be copied and imported into flows so that you can explore the configuration \[{"id" "7b889445 29cbfc","type" "ui text","z"
