No data for the given query On Azure Dashboard

This was probably a question for the Azure Monitor forum, but in case you don't have an answer, Dashboards default to 24hrs, so you have to change the date on the dashboard to be > 8days so your query can find the data.
I didn't see the need for a Union (based on the query supplied) or the complex itemType, so I have simplified the query - ignore if this isn't required.   Thanks
