neurotools.graphics.ztransform_plot_helpers module

neurotools.graphics.ztransform_plot_helpers.configure_matplotlib()

neurotools.graphics.ztransform_plot_helpers.add_circle(radius=1, lw=0.75, color='k', linestyle='-', n=360)

Parameters:

• radius (1)

• lw (0.75)

• color ('k')

• linestyle ('-')

• n (360)

neurotools.graphics.ztransform_plot_helpers.label_complex_axes(color='k')

neurotools.graphics.ztransform_plot_helpers.add_complex_axes(lw=0.75, color='w', limits=[(-2, 2), (-2, 2)])

neurotools.graphics.ztransform_plot_helpers.add_colorbar(im, aspect=20, pad_fraction=0.5, **kwargs)

neurotools.graphics.ztransform_plot_helpers.phase_magnitude_figure(z, limit=2)

neurotools.graphics.ztransform_plot_helpers.joint_phase_magnitude_plot(z, limit=[(-2, 2), (-2, 2)], color='w', draw_complex_axes=True, autoscale=False, nonlinearscale=True)

Parameters:

• z (2D complex-valued array)

• limit – Plot limits as [(real_min,real_max),(imag_min,imag_max)]

• color – Matplotlib color specifier for annotations

• draw_complex_axes – Overlay axes atop plot?

• autoscale – Automatically re-center magniture scale.

• nonlinearscale – Use arctan magnitude mapping to compress possibly infinite dynamic range

neurotools.graphics.ztransform_plot_helpers.do_bode_z(ω, Y, ax1, ax2, stitle='', label=None, color='k', linestyle='-', lw=0.8, drawlegend=True)

Parameters:

• ω (frequencies at which to evaluate)

• w (complex-valued output of z-transfer function at each frequency)

• ax1 (axis for the magnitude (gain) plot)

• ax2 (axis for phase plot)

neurotools.graphics.ztransform_plot_helpers.do_nyquist(ax, z, Y, extent=8)

neurotools.graphics.ztransform_plot_helpers.do_bode_and_nyquist(Y, extent=4)

neurotools.graphics.ztransform_plot_helpers.do_bode_s(ω, w, ax1, ax2, stitle='', label=None, color='k', linestyle='-', lw=0.8)

Parameters:

• ω (frequencies at which to evaluate)

• w (complex-valued output of z-transfer function at each frequency)

• ax1 (axis for the magnitude (gain) plot)

• ax2 (axis for phase plot)
