Max number of visualizations
The maximum number of visualizations there can be on a sheet is limited to the number of cells on a sheet, that is, 288 (24x12). The maximum practical number will be less than this because of the limited use for visualizations that are made up of only 1 cell.

| Names (title, dimension, footnote...) | Max. 255 characters |
