The options in the Scene's Views Properties panel allow you to select the elements that are shown in the 2D views in a scene, choose a view mode, and modify the background color. A Current Time Step slider is also available for time volumes.

2D view properties

See 3D Scene's View Properties for information about setting the properties for 3D scene views.

Options for 2D views
	Description
Show scale bar*	If selected, a floating scale bar will be shown in all 2D views of the current scene (see Scale Bar). Note All images usually need a scale bar on them for publication. This gives viewers an idea of the size of the objects (cells, organelles, blobs, and so on) in the image.
Show legends*	If selected, legends are shown in all views of the current scene (see Legends).
Show text annotations*	If selected, text annotations are shown in all views of the current scene (see Text Annotations).
View mode	The options in the View mode drop-down list allow you to change the View mode, which determines how image data is displayed. Slice… Displays data in the selected view in slices. Slab… Displays data in the selected view as a slab, in which the maximum, minimum, or average values within a thickness value are shown (see Viewing Images in Slab Mode). 3D… Displays data in the selected view in 3D (see 3D Views). Note that only one view in a scene layout can contain a 3D view.
Background color**	Indicates the background color of all 2D views in the current scene. To change, click the Background color swatch and then choose a new color in the Color dialog (see Choosing Colors).
Current time step	Available for time-enabled datasets, the Current time step slider lets you quickly navigate to a particular image interval. You can also use the Up and Down buttons to move between different time steps.
Change Unit***	Allows you change the default length and angle units displayed for text annotations, legends, measurements, and the dataset properties. To change the length units, click the Change Unit button and then choose the required unit in the Length Unit pop-up menu. To change the angle units, click the Change Unit button and then choose Degree or Radian in the Angle Unit pop-up menu.
Export Screenshot	Allows you to save a screen capture of the contents of the active view — including the scale bar, legends, annotations, regions of interest, and other objects that are visible onscreen — to a number of standard file formats (see Taking Screenshots).
