SUMMARY

Pivoting without dimensions is an unnecessary operation, and worse, it breaks sorting.

This PR prevents an unnecessary pivot operation by ensuring that pivoting only occurs when an x-axis, at least one metric, and at least one column are present.

  • Added a condition to check for the presence of columns before pivoting.
  • Updated the inline comment to explain the additional condition.

  • Consider adding tests to verify that the pivot operation is skipped when columns is undefined or an empty array.
