Chunk label

Chunks can be given an optional label, e.g.

This has three advantages:

  1. Navigate to specific chunks using the drop-down code navigator in the bottom-left of the script editor:

  1. Graphics produced by the chunks will have useful names that make them easier to use elsewhere.

  2. You can set up networks of cached chunks to avoid re-performing expensive computations on every run.

  • Important!
    • Your chunk labels should be short but evocative and should not contain spaces.
    • We recommend using dashes (-) to separate words (instead of underscores, _) and no other special characters in chunk labels.
    • Use whatever name, except: setup, which is used for a specific reason.
    • Additionally, chunk labels cannot be duplicated.
    • Each chunk label must be unique.
