plot_signal  R Documentation 
Visualize a signal over a graph.
plot_signal(z, f, size = 0.75, limits = range(f))
z 
A list containing graph data. This list must have the following components:

f 
Signal to plot. 
size 
Numeric. Dot size for nodes. Default is 0.75. 
limits 
Set colormap limits. 
This function allows visualization of a graph signal f
superimposed on the structure of a graph defined by z
. It offers an intuitive way to analyze the behavior of graph signals in the vertex domain.
If node coordinates xy
are not provided, they will be calculated using spectral methods spectral_coords
. For large graphs, this can be computationally intensive and may take significant time. Use with caution for large graphs if node coordinates are not supplied.
