skrf.plotting.plot_uncertainty_bounds_component(self, attribute, m=None, n=None, type='shade', n_deviations=3, alpha=0.3, color_error=None, markevery_error=20, ax=None, ppf=None, kwargs_error=None, **kwargs)

Plot mean value of a NetworkSet with +/- uncertainty bounds in an Network’s attribute.

This is designed to represent uncertainty in a scalar component of the s-parameter. for example plotting the uncertainty in the magnitude would be expressed by,

\[mean(|s|) \pm std(|s|)\]

The order of mean and abs is important.

Parameters:

• attribute (str) – attribute of Network type to analyze

• m (int or None) – first index of attribute matrix. Default is None (all)

• n (int or None) – second index of attribute matrix. Default is None (all)

• type (str) – [‘shade’ | ‘bar’], type of plot to draw

• n_deviations (int) – number of std deviations to plot as bounds

• alpha (float) – passed to matplotlib.fill_between() command. [number, 0-1]

• color_error (str) – color of the +- std dev fill shading. Default is None.

• markevery_error (float) – tbd

• type – if type==’bar’, this controls frequency of error bars

• ax (matplotlib axe object) – Axes to plot on. Default is None.

• ppf (function) –

  post processing function. a function applied to the

  upper and lower bounds. Default is None

  kwargs_errordict

  dictionary of kwargs to pass to the fill_between or errorbar plot command depending on value of type.

• **kwargs – passed to Network.plot_s_re command used to plot mean response

• self (NetworkSet) –

• kwargs_error (dict) –

Note

For phase uncertainty you probably want s_deg_unwrap, or similar. uncertainty for wrapped phase blows up at +-pi.
