Thank you for your contribution! All PRs should include the following sections. PRs missing these sections may be closed immediately.

Short description

This PR fixes an issue where the metric layout was being reset when the X-axis counter was changed (e.g. step to epoch) or when a run was removed from the displayed list.

AI Disclosure

We encourage the use of AI tooling in creating PRs, but the any non-trivial use of AI needs be disclosed. E.g. if you used Claude to write a first draft, you should mention that. Trivial tab-completion doesn't need to be disclosed. You should self-review all PRs, especially if they were generated with AI.
