How can you prevent users from viewing the date hierarchy based on the year in a stacked column chart?

To prevent users from viewing the date hierarchy based on the year in a stacked column chart, removing the year field from the date hierarchy on the X-axis is the most effective approach. When you alter the fields used in the visual, particularly by excluding a specific component of the hierarchy like the year, Power BI is instructed to display only the remaining elements, such as quarters, months, or days, without any reference to the year.

This method directly affects the visual representation of the data, ensuring that viewers will not see the year dimension in the chart. It maintains the integrity of the visual while adhering to the need to limit certain data displays.

The other options, such as applying filters based on specific time frames or adjusting the Maximum Range setting, might influence what data is shown but do not entirely eliminate the year field from the visual context. Therefore, simply removing the year from the date hierarchy ensures that it's completely excluded from the user's view.
