How to set meta.preferredVisualisationType

  • What Grafana version and what operating system are you using?
    grafana: 9.1.2
    os: Arch Linux

  • What are you trying to achieve?
    I am building a trace panel with data from influxdb.

  • How are you trying to achieve it?
    I am following Data API section in Tracing in Explore(The link is attached in the below question). Influxdb has returned those required fields. But I can’t set frame.meta.preferredVisualisationType to “trace”.

  • What happened?
    Even if grafana parsed response data successfully, it shows “No Data”.

  • What did you expect to happen?
    Trace will be show in trace panel.

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

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

After debuging, I found be the cause: “grafana/TraceView.tsx at 7979463bbf6a27aedfb7ed9e4aea0f0822efd12d · grafana/grafana · GitHub”. It checks: frame.meta.preferredVisualisationType === 'trace'. After removing this condition, trace is shown in the panel.

I’m a newbie to grafana. Is there an official way to set preferredVisualisationType? Or should i create an issue in github?

Thank you for your works!
