# mne.viz.circular_layout¶

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

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”. node_angles : array, shape=(len(node_names,)) Node angles in degrees.
