In Pivot, what field is used to define the horizontal axis of the Pivot report?

The correct choice identifies the field that determines the horizontal axis of a Pivot report. "Pivot On" signifies the field selected to categorize the data across the top of the report, allowing users to analyze trends, summarize results, or visualize data distributions efficiently.

By utilizing the "Pivot On" field effectively, users can manipulate how data points are grouped and displayed, providing clarity and enhancing the ability to extract valuable insights from the dataset. It serves as the primary mechanism for structuring the report's view along the horizontal dimension, which is critical for comparative analysis and data storytelling. This option thus encapsulates the core functionality of setting the directional flow of data representation within the Pivot report framework.
