`view`

Sets or gets the viewing angle of 3-D axes as azimuth and elevation.

Category: Graphics > Formatting and Annotation

Syntax

view(az, el)

Sets the azimuth and elevation, in degrees.

view(2)

Uses the default 2-D view, [0 90], looking down the z-axis.

view(3)

Uses the default 3-D view, [-37.5 30].

[az, el] = view

Returns the current angles.

Description

The two angles describe where the viewer stands relative to the axes. view(0, 90) is a top view, view(0, 0) looks along the y-axis from the front, and view(90, 0) looks from the side. For 2-D plots the default is [0 90].

The viewpoint is stored in the axes property View. Rotating the axes by mouse changes it as well.

Input arguments

az: Azimuth: the rotation about the vertical axis, in degrees. Positive values turn the viewpoint counterclockwise as seen from above.
el: Elevation: the angle above the xy plane, in degrees. 90 looks straight down.

Output arguments

az, el: Current azimuth and elevation. With one output, a two-element vector [az el].

Example

Look from the side

surf(peaks(25))
view(3);
v3 = view
view(90, 0)
v = view

Output

v3 = 1×2

  -37.5000   30.0000
v = 1×2

    90     0

Notes

In MatLivre the form view([x y z]), which takes a direction vector, is not supported; give azimuth and elevation instead.
