- If the workbook opens for viewing, click Edit.
- Click Menu on the workbook toolbar and select Workbook Properties.
- Use the Visualization Loading Overlay slider to set the opacity of the visualization overlay to a value between 1-100, where 1 is transparent, and 100 is opaque.
- Click OK.
- Click Save.
