What Grafana version and what operating system are you using?
We are using Grafana 10.4.1 on a Linux host. -
What are you trying to achieve?
I am querying my InfluxDB database with a Flux query and trying to show unique assessments (think of it like a tag, with each different assessment/tag having a unique GUID) on a geomap panel. I am also running an SQL query against a SQL Server database to pull in icon “photos” that I want to display on my Geomap panel at the locations returned in the first query. I have an inner join transform running against a common field between the two queries. -
How are you trying to achieve it?
I am using the following flux query “A” in Grafana:
from(bucket: "Assessment_Data")
|> range(start: v.timeRangeStart, stop: v.timeRangeStop)
|> filter(fn: (r) => r["_measurement"] == "current_assessments")
|> filter(fn: (r) => r["_field"] == "assessmentlat" or r["_field"] == "assessmentlon" or r["_field"] == "assessmentid" or r["_field"] == "assessmentcreated" or r["_field"] == "assessmentcomments" or r["_field"] == "assessmentcreatedby" or r["_field"] == "assessmentelement" or r["_field"] == "assessmentfeeder" or r["_field"] == "assessmentcategory")
|> pivot(rowKey: ["_time"], columnKey: ["_field"], valueColumn: "_value" )
|> drop(columns: ["_start", "_stop"])
|> group(columns: ["assessmentid"])
|> last(column: "_time")
And, I am using the following SQL query “B” in the same Grafana panel:
SELECT Name AS "assessmentcategory", ImageIcon FROM D*snip*SQLReplica.dbo.DefaultType
As described above, I am using a Join transform to do an inner join against the assessmentcategory field which is present in both queries A and B. I then configured the Assessments data layer as a Photo using the lat and lon out of Query A to pick up locations and using the ImageIcon field that originated with query B and contains a binary bitmap image file.

What happened?
I got the following map:

What did you expect to happen?
I expected a GeoMap with my icons at each assessment location instead of question marks.
I realize that this is a beta feature, but I was hoping to see how it worked and get an idea if it could be a good long-term solution for one of our needs. Any guidance on what I am doing wrong or missing here would be much appreciated.
