What view granularity can be defined in a calendar chart?

The correct answer indicates that the view granularity in a calendar chart can be adjusted from daily to monthly. This flexibility is essential for users who need to visualize data across different timeframes to analyze trends, patterns, or operational metrics effectively.

By allowing for daily, weekly, and monthly views, users gain the ability to drill down into specific days for detailed analysis or zoom out to a monthly view for a broader perspective. This granularity supports various analytical needs, from examining short-term fluctuations (daily) to assessing longer-term performance and trends (monthly).

The other options are limited in scope. Weekly only restricts the time granularity, preventing users from seeing daily variations or monthly summaries. Only monthly view offers a high-level perspective but lacks the detail available in daily or weekly views. Quarterly view limits data visibility to one specific quarter, which may not be sufficient for ongoing analysis. Thus, the ability to choose from daily to monthly significantly enhances the usefulness of a calendar chart in data visualization.
