    Chatted privately with Helen - the solution in this case was to make sure that the DateTime value was sent in the proper former format: 2016-08-23T16:13:05.970Z. Improperly formatted DateTimes may cause unpredictable visualization behavior, as seen above.

Hi,

 

I came across this reply concerning the real-time streaming feature. You are asking if the user is running the chart from a dashboard or report? Is there really a way to include streaming dataset into reports? The example from the PowerBI documentation only describes how to use them from a dashboard and the visual components that can be used are pretty limited:

Thanks.

You can create reports from streaming data sets only if you enable the historical data capture.

 

Hope this helps!

    dramus Yes it did in fact help a lot and I just created a report from a streaming dataset (of type API). However I have this report that receives live data but does not update unless I press the refresh button. Here are my observations from my report based on a streaming dataset:

    • Looking at report: No autorefresh, I need to click on the refresh button to see new data.
    • Looking at full report(pin live page) from dashboard: No autorefresh, no refresh button therefore cannot look at new data unless I press F5
    • Looking a single visual (pin visual) from dashboard: The view autorefreshes as data is coming in.

     

    How could this refresh from "pin live view" or report directly ?

     

    Thanks

      If it's a streaming dataset, then the Dashboard should be updating automatically (Mine does). The report you do need to hit the refresh button for it to update.

       

      There was a bug that if you had more than one streaming dataset on a dashboard, then it sometimes would not. Microsoft know about it, but I don't know if it's been fixed yet.

      I am facing the same problem, I am streaming data via streaming analytics to create report and pinned live to dashboard, but I havev to hit refresh to get the updated data. Did you find any solution?
