Dashboard Variables with openHistorian

Apologies all - I’m a Grafana nooby, so this is probably really basic, but any help would be much appreciated!

  • What Grafana version and what operating system are you using?
    Grafana Version 9.5.1, Windows Server 2016

  • What are you trying to achieve?
    I am trying to get the dashboard to display time varying data, with reference to a user selected variable. However the user variable displays as the tag title, e.g.:

    "SSE_BEAU4_BG1:VR_VA_400.ang"
    

Whereas I’d like it to display as a more user freindly way, e.g.:

  "Beauly 400kV"
  • How are you trying to achieve it?
    Under Dashboard Settings → Variables, and Custom Options, I have tried to list the variable as:

    label("Beauly 400kV", SSE_BEAU4_BG1:VR_VA_400.ang)
    
  • What happened?
    The entry in the variable drop down box appears literally as “label(“Beauly 400kV”, SSE_BEAU4_BG1:VR_VA_400.ang)”, and it fails to query the underlying data source correctly.

  • What did you expect to happen?
    I’m trying to get the selected variable to reference the underlying tag, and pass that to calculations carried out elsewhere in the dashboard.
