Hello all Grafana community members, I am a beginner in Grafana Loki. How do I visualize the data field that I want here, for example “src_ip” into a horizontal bar (like the example of the second picture) ?. I can only find Grafana visualization only in the form of tables and Logs.
Note: my log data is in “json” format which comes from the local machine sent to the Loki agent. Thank you for reading my message.
Maybe something like sum by (ip) (count_over_time({SELECTOR} [$__auto])). See Metric queries | Grafana Loki documentation for metrics query example.

Thank you for taking the time to reply to my message. Through your advice, I was finally able to get the results I wanted. However, I want to remove the data such as “{}” (First image) and “remote_host=”" (Second image), how can I do that? I have used the functions of " != “{}” " (for the first image) and " != “” " (for the second image) but the result I get is no data. My second question is how to make the data displayed is the value without the label, for example in the first image I want the data displayed “admin”, “admin1” and so on without {username=}. Also for the second image, I only want to display the IP address without {remote_host=) Sorry if it’s troublesome, can you help me again?

Thank you for taking the time and referring the post to me. The solution in the post you referred to worked well for my second question. Now I need a solution to the problem of how to hide data like “{}” (First image) and “remote_host=”" (Second image). I’ve been looking for that solution and still haven’t found it so far. Any help would be greatly appreciated.
One of these should work:
If you already know the label should exist you can add a simple check such as username=~".+".
You can check for error after a query to make sure you don’t aggregate on results with errors, like so:
{SELECTOR}
| some query
| some more query
| __ERROR__ = ""
