def scatter_plot( self, **kwds ):
'''
Generates a scatter plot using the first 2 princpal components as axes.
**Keywords**:
- *vectors* = True if original axes should be plotted as vectors in this space. Default is False.
- *path* = a path to save this figure to
- *dpi* = the dpi of the saved figure
- *width* = the width (in inches) of the saved figure

"""
Plot the spatial receptive fields for multiple cells.
Parameters
----------
cells : list of array_like
A list of spatiotemporal receptive fields, each of which is
a spatiotemporal array.
dx : float, optional
The spatial sampling rate of the STA, setting the scale of the
x- and y-axes.
ax : matplotlib Axes object, optional
The axes onto which the ellipse should be plotted.
Defaults to a new figure.
Returns
------
fig : matplotlib.figure.Figure
The figure onto which the ellipses are plotted.
ax : matplotlib.axes.Axes
The axes onto which the ellipses are plotted.
