TopoPlots

Documentation for TopoPlots.

A package for creating topoplots from data that were measured on arbitrarily positioned sensors:

using TopoPlots, CairoMakie
f = Figure(;resolution=(800,280))
topoplot(f[1,1],rand(20), rand(Point2f, 20))
topoplot(f[1,2],rand(20), rand(Point2f, 20); contours=(color=:white, linewidth=2),
         label_scatter=true, bounding_geometry=Rect(0,0,1,1), colormap=:viridis)
eeg_topoplot(f[1,3],rand(20),1:20;positions=rand(Point2f, 20), colormap=:Oranges)

It also contains some more convenience methods for EEG data, which is explained in EEG Topoplots.

You can also use TopoPlots' interpolators as a simple interface to regrid irregular data. See Interpolation for more details.
