Hello,
To make the line wider, you need to increase the “Line width” option (either in the Display options or in the Series Override options).

And to make the line appears in front of the bars, you have two solutions:
- If you are using 2 queries to get your data, you can change the order of the queries: the query that you want in front of the other must be the last one.
- You can use the Series override option “z-index” like below:

If you have trouble making these changes, do not hesitate to post a screenshot of your panel configuration.
Great. Thanks got that to work just fine!
