draw_zne_extrapolators(result, indices=None, names=None, num_stds=1, max_mag=10, max_std=0.2, height=500, width=1000, colorscale='Aggrnyl')

Plot the zero noise extrapolation data in an EstimatorPubResult .

This function generates a subfigure for each extrapolator.

Parameters

result (EstimatorPubResult) – An EstimatorPubResult.
indices (Sequence[tuple[int, ...]] | None) – The indices of the expectation values to include in the plot. If None, includes all values. See ZneOptions for information on the indexing scheme.
names (Sequence[str] | None) – The names to assign to the expectation values. If None, the names correspond to the indices.
num_stds (int) – The number of standard deviations to include around each fit.
max_mag (float) – The maximum magnitude of expectation values to include. If evs_extrapolated has a greater magnitude than this value, the expectation value is omitted from the plot.
max_std (float) – The maximum standard deviation to include. If stds_extrapolated is greater than this value for an expectation value and extrapolator, the fit is omitted from the plot.
height (int) – The height of the plot in pixels.
width (int) – The width of the plot in pixels.
colorscale (str) – The colorscale to use.

Returns

A plotly figure.

Raises

ValueError – If result does not contain zero noise extrapolation data.
ValueError – If the length of names is not equal to the length of indices.
