I’m using Apex Chart to show data and I have some problems trying to populate data series with a query.
If I use a Tag History I’m able to show it selecting the tag, setting to Value Format to “DOCUMENT” and add a configure trasform for having as result t_stamp as 0 index and tag_name as 1 index.
I don’t know what I was looking at, you are right because actually the chart works good with JSON return format, I do apologize with all of you for the mistake.
