fix: yvalMeta .name null check

[oneirocosm]

While it is rare, we have had users report an error where the access of .name in SingleLinePlot causes a bug. The only time this could happen would be a null yvalMeta. This makes it so the .name check is skipped if yvalMeta is null. Addresses #1724.

Walkthrough

The pull request introduces a minor modification in the frontend/app/view/sysinfo/sysinfo.tsx file, specifically within the SingleLinePlot function. The change involves updating the syntax for accessing the name property of yvalMeta by implementing optional chaining (?.). This modification enhances the code's resilience by preventing potential runtime errors when yvalMeta might be undefined or null. The change is a defensive programming technique that ensures the code can handle scenarios where the yvalMeta object might not be present, without causing an exception. The overall functionality and structure of the SingleLinePlot component remain consistent with the previous implementation.

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

450-450: LGTM! Consider additional defensive programming.

The optional chaining operator (?.) correctly prevents the error when accessing the name property of a null yvalMeta. However, since plotMeta.get(yval) can return undefined, consider providing a default name for better UX:

-            Plot.text([yvalMeta?.name], {
+            Plot.text([yvalMeta?.name ?? yval], {

This ensures that even if yvalMeta is missing, the plot will display the metric key as a fallback.
