The only way I could find to filter the data for the last hour is to create a dashboard with the stream analytics data and then use the Q&A box at the top to create the required tables / charts.

 

To do this you just need to add a phrase like "time in the 60 minutes".  So the complete Q&A phrase to create a grpah for the data in the last hour would be something like "show the average of Temperature by time as line chart where time is in the last 60 minutes"

The Q&A field is nice, but does not help to set a timeline to a dashboard. And thats mandatory. We are also using ASA and whant to show realtime data for the last 2 hours and thats not possible. Not in ASA and not in the Power BI web app. Why?

      Currently, you should be able to use Q&A to accomplish this. Can you try the following steps:

       

      1. Go to the dashboard in question

      2. In the Q&A box, type "[value field] by [time feld] last one hour" - e.g. "temperature by time last one hour"

      3. Once you're satisfied with the visual produced by Q&A, press "pin visual" in the top right

      4. The visual will now be pinned to the dashboard, and will update in real-time

       

      Longer term, we're doing work to allow Azure Stream Analytics to output to the recently released streaming datasets. Streaming tiles, which are built atop streaming datasets, have native support for displaying data over a set time window. Look out for private preview of this sometime before the end of the year.
