Hi,

We would like to display two string tags in the Perspective Power Chart alongside the numeric process tags, as this would provide users with additional context and insights. I attempted to add the string tags; however, the chart displays the tag source as "Not Available" even though the tags exist and are accessible. I have attached a screenshot for reference.

Thanks

Continuing the discussion from [Showing historized string tags along with other numeric tags](https://forum.inductiveautomation.com/t/showing-historized-string-tags-along-with-other-numeric-tags/116694):

~~I don't believe this is possible to do with the Power Chart; it does not work for string tags.~~

~~The only thing you _could_ do is to hijack the annotations table and insert the text into here:~~

Actually, I stand corrected - it _does_ appear to work in 8.1.51

This is working fine for me now. Earlier, it was showing an error, so I tried executing `system.tag.queryTagHistory()`. I noticed that no data was being returned for the tag, even though the Tag Browser showed the history icon and tag history was enabled in the tag configuration.

To troubleshoot, I simply disabled tag history and then re-enabled it. After doing this, the query started returning data and the issue was resolved.

I also verified in the Query Browser that the data type value for the tag was `0`.
