How Can I set a different urls as Data Links for each plot of multiple series?

Grafana Data Links
1

Hello.

I was able to set the data link whose value is from the query(url column) to only the first series on the time series graph, but I want to set it to all series as well. There is a “about:blank” link on the plot of every other series.

For example, there is a data link in the plot of the green series, but not in the others.
How can I solve this problem?

settings:

  • I’m using “grafana/grafana:11.1.0”
  • Visualization: Time series
  • Query
    • “SELECT timestamp, name, numeric_value, url FROM table ORDER BY timestamp ASC”
      • timestamp is for X axis, numeric_value is for Y axis.
      • I want to use the value of “url” as data link
  • Format: Table
  • Transform data
    • Partition by values: name
      • This is to draw multiple series partitioned by name on one panel.
  • data link
    • ${__data.fields[url]}

Query result sample:

| timestamp | name | numeric_value | url |
| 2024-07-17 09:00:00 | aaa | 10 | https://.aaa1… |
| 2024-07-17 09:00:00 | bbb | 15 | https://.bbb1… |
| 2024-07-18 09:00:00 | aaa | 20 | https://.aaa2… |
| 2024-07-18 09:00:00 | bbb | 25 | https://.bbb2… |
| 2024-07-19 09:00:00 | ccc | 10 | https://.ccc1… |
| 2024-07-20 09:00:00 | ccc | 15 | https://.ccc2… |

The value of url is different from each other.

Thank you.
