Topomap
(y, xax=None, ds=None, sub=None, vmax=None, vmin=None, cmap=None, contours=None, proj='default', res=None, interpolation=None, clip='even', clip_distance=0.05, head_radius=None, head_pos=0, im_interpolation=None, sensorlabels=None, mark=None, mcolor=None, axtitle=True, xlabel=None, margins=None, **kwargs)¶ Plot individual topogeraphies
Parameters: - y : (list of) NDVar, dims = ([case,] sensor,)
Data to plot.
- xax : None | categorial
Create a separate plot for each cell in this model.
- ds : None | Dataset
If a Dataset is provided, data can be specified as strings.
- sub : str | array
Specify a subset of the data.
- vmax : scalar
Upper limits for the colormap (default is determined from data).
- vmin : scalar
Lower limit for the colormap (default
-vmax
).- cmap : str
Colormap (default depends on the data).
- contours : int | sequence | dict
Contours to draw on topomaps. Can be an int (number of contours, including
vmin
/vmax
), a sequence (values at which to draw contours), or a**kwargs
dict (must contain at least the “levels” key). Default is no contours.- proj : str | list of str
The sensor projection to use for topomaps (or one projection per plot).
- res : int
Resolution of the topomaps (width = height =
res
).- interpolation : ‘nearest’ | ‘linear’ | ‘spline’
Method for interpolating topo-map between sensors (default is based on mne-python).
- clip : bool | ‘even’ | ‘circle’
Outline for clipping topomaps: ‘even’ to clip at a constant distance (default), ‘circle’ to clip using a circle.
- clip_distance : scalar
How far from sensor locations to clip (1 is the axes height/width).
- head_radius : scalar | tuple
Radius of the head outline drawn over sensors (on sensor plots with normalized positions, 0.45 is the outline of the topomap); 0 to plot no outline; tuple for separate (right, anterior) radius. The default is determined automatically.
- head_pos : scalar
Head outline position along the anterior axis (0 is the center, 0.5 is the top end of the plot).
- im_interpolation : str
Topomap image interpolation (see Matplotlib’s
imshow()
). Matplotlib 1.5.3’s SVG output can’t handle uneven aspect withinterpolation='none'
, useinterpolation='nearest'
instead.- sensorlabels : ‘none’ | ‘index’ | ‘name’ | ‘fullname’
Show sensor labels. For ‘name’, any prefix common to all names is removed; with ‘fullname’, the full name is shown.
- mark : Sensor index
Sensors which to mark.
- mcolor : matplotlib color
Color for marked sensors.
- axtitle : bool | sequence of str
Title for the individual axes. The default is to show the names of the epochs, but only if multiple axes are plotted.
- xlabel : str
Label below the topomaps (default is no label).
- margins : dict
Layout parameter.
- …
Also accepts General layout parameters.
Notes
