Curtains tab of the Layout Options page
Overview
Curtains allow you to change the color and pattern of the background of a layout, enabling you to more easily identify specific time periods in relation to the overall timescale. For example, you might use a curtain to highlight the colder or warmer months of the year if the outside temperature is relevant to your project.
Use the Curtains tab of the Layout Options page to define and edit curtains.
