Can I add Field Override against the result of a Transformation that is in-between other transformations

Grafana Bar Chart Panel

  • What Grafana version and what operating system are you using? Grafana v10.2.2

  • What are you trying to achieve? I have a panel with ‘Bar Chart’ which is constructed from the result of a query that returns different fields and count. Each field and its count is represented in Bars. I need to set different colors for different bars. There are four transformations ‘Extract fields’ > ‘Filter by name’ > ‘Organize Fields’> ‘Reduce’. I need to apply ‘Add Field Override’ to a Field filtered by ‘Display Name’. This Field is to be from the Third Transformation. In this Transformation, I changed a Field named ‘launched’ to ‘App Launched’. When I try to ‘Add Field Override’ and look for the field, it returns the result of the last transformation (Reduce)’. Means, there is only one field available that is ‘Count’

  • How are you trying to achieve it? As explained above, there are four transformations ‘Extract fields’ > ‘Filter by name’ > ‘Organize Fields’> ‘Reduce’. I need to apply ‘Add Field Override’ to a Field filtered by ‘Display Name’. This Field is to be from the Third Transformation. In this Transformation, I changed a Field named ‘launched’ to ‘App Launched’. When I try to ‘Add Field Override’ and look for the field, it returns the result of the last transformation (Reduce)’. Means, there is only one field available that is ‘Count’

  • What happened? Since there is a transformation ‘Reduce’ after the ‘Organize fields’ transformation, the ‘Add Field Override’ for the Panel returns only one field that is ‘Count’ and so I am no table to set any override for a field that is result of an intermediate transformation.

  • What did you expect to happen? I need ‘Add Field Override’ to a field that is resulted from the third Transformation ‘Organize Fields’ . I need to color different bars with different colors

  • Can you copy/paste the configuration(s) that you are having problems with? - NA

  • Did you receive any errors in the Grafana UI or in related logs? If so, please tell us exactly what they were. - NA

  • Did you follow any online instructions? If so, what is the URL? - NA

A picture paints a thousand words so if you could post a snippet (even with dummy data) of what you’re trying to achieve.

But the the short answer should be yes - field overrides should technically still apply even for transformation generated column fields.

Also, any reason why you’re still using v10 if v12 is already out for a while? Who knows what bugs / glitches are in there.
