# aspect3d

0th

Percentile

##### Set the aspect ratios of the current plot

This function sets the apparent ratios of the x, y, and z axes of the current bounding box.

Keywords
dynamic
##### Usage
aspect3d(x, y = NULL, z = NULL)
##### Arguments
x

The ratio for the x axis, or all three ratios, or "iso"

y

The ratio for the y axis

z

The ratio for the z axis

##### Details

If the ratios are all 1, the bounding box will be displayed as a cube approximately filling the display. Values may be set larger or smaller as desired. Aspect "iso" signifies that the coordinates should all be displayed at the same scale, i.e. the bounding box should not be rescaled. (This corresponds to the default display before aspect3d has been called.) Partial matches to "iso" are allowed.

aspect3d works by modifying par3d("scale").

##### Value

The previous value of the scale is returned invisibly.
