Hello everyone,
I am having an issue understanding how data gets purged from charts in a streaming analytics to power bi setup. I have a bar chart that displays the count of trips that are late by 15+ minutes, 30+, 45+, etc... (think delivery driver). With streaming analytics, I am able to process messages from an event hub and send the results to the power bi bar chart. My query does a group by on the trip id and when I test my query it only ever produces one row per trip, which is what I want. However, over time, I notice the bar chart is holding on to the result of each past query. The net effect is I have a bar chart displaying trip A is 10 min late, then trip A is 12 min late, and then trip A is 14 min late. What I want to see is just that trip A is 14 min late.
How can I purge (or update) existing data in power bi via streaming analytics?
Thanks for the help!
Mark
