norm_coords: Normalize coordinates for plotting graphs

In igraph: Network Analysis and Visualization

Normalize coordinates for plotting graphs

Description

Rescale coordinates linearly to be within given bounds.

Usage

norm_coords(
  layout,
  xmin = -1,
  xmax = 1,
  ymin = -1,
  ymax = 1,
  zmin = -1,
  zmax = 1
)

Arguments

layout	A matrix with two or three columns, the layout to normalize.
xmin, xmax	The limits for the first coordinate, if one of them or both are NULL then no normalization is performed along this direction.
ymin, ymax	The limits for the second coordinate, if one of them or both are NULL then no normalization is performed along this direction.
zmin, zmax	The limits for the third coordinate, if one of them or both are NULL then no normalization is performed along this direction.

Details

norm_coords() normalizes a layout, it linearly transforms each coordinate separately to fit into the given limits.

Value

A numeric matrix with at the same dimension as layout.
