Plot display settings

Set the default once per Python session or notebook:

from spinfinity import plotting

plotting.set_display_mode("responsive")

Use "fixed" for each plot's preferred width, "responsive" to fill the available width, or "no" to suppress display. These settings apply to all package plotting functions. Override a single call with show="fixed", show="responsive", or show="no"; the default show=None inherits the setting.

Helperfunctions

The helperfunctions module provides a Fourier transform calculation and three fitting functions:

Function	Model	Parameter order
fit_fano	Symmetric Lorentzian peak or dip with constant offset	[A, x0, FWHM, C]
fit_exponential	Exponential decay with constant offset	[A, T, C]
fit_oscillation	Exponentially damped cosine with constant offset	[A, T, f, phi, C]

The fitting functions return xfit, yfit, popt, and perr: a dense plotting grid, the fitted curve, the fitted parameters, and their estimated one-standard-deviation uncertainties.
