Scaled

Scaled[{x,y,}]

gives the position of a graphical object in terms of coordinates scaled to run from 0 to 1 across the whole plot range in each direction.

Scaled[{dx,dy,},{x0,y0,}]

gives a position obtained by starting at ordinary coordinates {x0,y0,}, then moving by a scaled offset {dx,dy,}.

Details

  • Scaled can be used to specify scaled coordinates in any two or threedimensional graphics primitive.
  • You can use Scaled to represent objects that occupy a fixed region in a plot, independent of the specific range of coordinates in the plot.
  • Scaled refers only to the region of a plot defined by its PlotRange and PlotRangePadding. It does not take account of elements such as tick labels, or of margins introduced by ImageMargins.
  • Scaled can be used not only for coordinates, but also for scalar length measures such as radii.
  • In 2D graphics, Scaled[r] is taken to be relative to the width of the whole graphic. In 3D graphics, it is taken to be relative to the diagonal of the 3D bounding box.

Properties & Relations  (6)

Scaled is proportional to PlotRange. ImageScaled is proportional to ImageSize:

Scaled operates relative to the plot range:

ImageScaled operates relative to the whole image:

Scaled coordinates do not have to be between 0 and 1:

In 2D the transformation from world coordinates to Scaled coordinates is given by:

From Scaled to world coordinates:

In 3D the transformation from world coordinates to Scaled coordinates is given by:

Possible Issues  (3)

Objects with Scaled coordinates outside 0 and 1 may not be displayed in 3D:

Using Scaled sizes will depend on the PlotRange:

Using automatic plot range with Scaled may cause an ambiguity:

Having objects in the graphic with nonscaled coordinates will disambiguate the scale:

Using a fixed plot range will also disambiguate the scale:
