About Moving or Hiding Visualizations on a Canvas Using Presentation Settings
When configuring the presentation settings in Manual Mode, the base canvas' Layout property in the workbook editor determines if the canvas includes white spaces or overlaps when you adjust the canvas' layout for the consumer view.
See About Canvas Layout Properties and Update Canvas Properties.
When the base canvas' Layout property is set to Auto Fit in the workbook editor, then in the consumer view the canvas layout automatically adjusts to accommodate any visualizations that you move or hide. When you preview the canvas or select Reset Adjustments to remove the canvas' layout changes, no white spaces and overlaps are displayed.
When the base canvas' Layout property is set to Freeform in the workbook editor, then the canvas layout doesn't automatically adjust to accommodate any visualizations that you move or hide in the consumer view. When you preview the canvas or select Reset Adjustments to remove the canvas' layout changes, white spaces and overlaps are displayed.
If your canvas is set to Freeform and you move or hide visualizations for the consumer view using the presentation settings, or reset the canvas, be sure to rearrange the visualizations to prevent any white spaces or overlaps. See Show or Hide Canvas Visualizations for Consumers and Reset a Canvas for Consumers.
