Transform Filter by name returns no values

When I try to transform a query by using filter by name, the filter returns no data despite values being within the query.
In the images you see a sample output wellname of 231A-1002H. Whether I use a begins with or contains regex, seen in the images, it still returns no data.
What is causing the filter to produce no data with the expression I have entered? What should I enter to return data for contains 231 or is exactly 231A-1002H


Hi,

The filter by name include/exclude a field from the query, it doesn’t do check on the values. In other words, if I have this query :

And I do a Regex to ‘T\w*’ I will only get a column (which is the Time column)

So this transformation is not what you are looking for. Indeed I’m still looking for a substring of values, I’ll keep you updated.

Good Luck

Hi,

Here you go :

But you must be on Grafana 7.4+ (which is yet to be released)

Good Luck

That makes sense, thanks for the help! Still useful to use in a different setting as you showed
