mne.viz.circular_layout

mne.viz.circular_layout(node_names, node_order, start_pos=90, start_between=True, group_boundaries=None, group_sep=10)[source]

Create layout arranging nodes on a circle.

Parameters:

node_names : list of str

Node names.

node_order : list of str

List with node names defining the order in which the nodes are arranged. Must have the elements as node_names but the order can be different. The nodes are arranged clockwise starting at “start_pos” degrees.

start_pos : float

Angle in degrees that defines where the first node is plotted.

start_between : bool

If True, the layout starts with the position between the nodes. This is the same as adding “180. / len(node_names)” to start_pos.

group_boundaries : None | array-like

List of of boundaries between groups at which point a “group_sep” will be inserted. E.g. “[0, len(node_names) / 2]” will create two groups.

group_sep : float

Group separation angle in degrees. See “group_boundaries”.
Returns:

node_angles : array, shape=(len(node_names,))

Node angles in degrees.
