Which method allows a widget size to remain constant in a dashboard?

Locking the rows and columns that a widget covers is the method that ensures the size of the widget remains constant within a dashboard. When rows and columns are locked, they create a fixed area for the widget to occupy, preventing any adjustments to its dimensions as users interact with the dashboard or as the layout changes. This is especially useful in dynamic environments where other elements might shift or resize, as it provides a stable viewing point for key information presented by the widget.

Other methods, such as changing color settings or moving the widget to another dashboard, do not address the size or placement stability. Similarly, limiting user access focuses on user permissions rather than the structural aspects of widget sizing within the dashboard. Therefore, locking the rows and columns is the most effective strategy to maintain a constant widget size.
