Hello! I'm an OSIsoft engineer who's actually worked on building a lot of examples with Operations dashboard--I'd be glad to help. I'm afraid that the example that you're seeing here is actually a much-outdated video of our Esri integration--this shows, specifically, a custom example that was created via custom code. It actually doesn't represent the final version or features of our integration--what you see in the video isn't a released product, rather a custom solution that shows how data from the PI System can be visualized in ArcGIS. I'm glad to hear that you're familiar with Operations Dashboard, because that's certainly how we would recommend setting up a dashboard that allows lasso calculations, for example. We have an updated YouTube playlist that shows the current version of the Integrator here: OSIsoft and Esri: Bringing Space & Time Together - YouTube And specifically, you can see an example of such area-select summary calculations, using Esri's Operations Dashboard, at this specific timestamp: https://youtu.be/DuELBTFDYcM?list=PL40vX05wOAcCHPZpCMc-Diwn85L2ciz29&t=173 I hope this helps!
