Data Dashboard allows you to create custom, portable views of National Instruments LabVIEW applications. Using this application, you can create dashboards to display the values of network-published shared variables and deployed LabVIEW Web services on indicators, such as charts, gauges, textboxes, and LEDs.
Data Dashboard is available for Apple iPad and Android tablets in the iTunes and Google Play Store.This tutorial describes the basic steps for getting started with Data Dashboard. You can find the same content plus more in the tutorials that are installed with the Data Dashboard app. For more background information on how Data Dashboard interfaces with network shared variables and LabVIEW Web Services, please see Integrating NI Data Dashboard for LabVIEW into your LabVIEW Applications.
Your new dashboard will open and appear.
Before you can link your dashboard controls and indicators, you need to have variables to connect to. If you already have a network-published shared variable deployed, you can move to the Connect to Shared Variables section. To deploy network-published shared variables you will need to create a project in LabVIEW.
Now that you have placed your indicators and deployed your network-published shared variables, you can link your dashboard to your shared variables.
In this section of the tutorial you will be creating a Web Service and a web method to connect your Data Dashboard. The following steps describe the process of building a Web Service with LabVIEW 2013 and later.
Now that you have placed down your indicators and deployed your Web Service, you can link your dashboard indicators to your Web methods. There are two ways to connect to a Web method, polling and calling. Polling a Web method calls the Web method continuously every .3 to 30 seconds as specified by the user. Calling a Web method only calls the Web method when the Call button is pressed. For this tutorial, we will use a polling connection to continuously populate the data on our chart and indicator.
