The POV button is enabled for multiple-grid sheets that contain only one grid, making it possible for you to toggle the button to show or hide the POV toolbar. The POV button remains disabled on multiple-grid sheets that contain more than one grid.

On multiple-grid sheets that contain one grid, the POV dimensions are displayed both in the grid and in the toolbar. On regular ad hoc sheets, POV dimensions are displayed in the grid only if the POV toolbar is hidden.
