plotHeadTopography(topography,
sensorlocations,
plotsensors=False,
resolution=51,
masked=True,
plothead=True,
plothead_kwargs=None,
**kwargs)
| source code
|
Plot distribution to a head surface, derived from some sensor locations.
The sensor locations are first projected onto the best fitting sphere and
finally projected onto a circle (by simply ignoring the z-axis).
- Returns:
- (map, head, sensors)
The corresponding matplotlib objects are returned if plotted, ie.
if plothead is set to False, head will be None.
- map
- The colormap that makes the actual plot, a
matplotlib.image.AxesImage instance.
- head
- What is returned by plotHeadOutline().
- sensors
- The dots marking the electrodes, a matplotlib.lines.Line2d
instance.
Parameters:
- topography: array
- A vector of some values corresponding to each sensor.
- sensorlocations: (nsensors x 3) array
- 3D coordinates of each sensor. The order of the sensors has to match
with the
topography vector.
- plotsensors: bool
- If True, sensor will be plotted on their projected coordinates.
No sensor are shown otherwise.
- plothead: bool
- If True, a head outline is plotted.
- plothead_kwargs: dict
- Additional keyword arguments passed to plotHeadOutline().
- resolution: int
- Number of surface samples along both x and y-axis.
- masked: bool
- If True, all surface sample extending to head outline will be
masked.
- **kwargs:
- All additional arguments will be passed to
pylab.imshow().
