Characteristic

class plasmapy.diagnostics.langmuir.Characteristic(

bias: Annotated[Quantity, Unit('V')],

current: Annotated[Quantity, Unit('A')],

)

Bases: object

Class representing a single I-V probe characteristic for convenient experimental data access and computation. Supports units.

bias

Array of applied probe biases in units convertible to V.

Type:

astropy.units.Quantity, ndarray

current

Array of applied probe currents in units convertible to A.

Type:

astropy.units.Quantity, ndarray

Methods Summary

get_padded_limit(padding[, log])	Return the limits of the current range for plotting, taking into account padding.
get_unique_bias([inplace])	Remove any duplicate bias values through averaging.
plot()	Plot the characteristic in matplotlib.
sort()	Sort the characteristic by ascending bias.

Methods Documentation

get_padded_limit(padding, log: bool = False)

Return the limits of the current range for plotting, taking into account padding. Matplotlib lacks this functionality.

Parameters:

• padding (float) – The padding ratio as a float between 0.0 and 1.0.

• log (bool, optional) – If True the calculation will be performed on a logarithmic scale. Default is False.

get_unique_bias(inplace: bool = False)

Remove any duplicate bias values through averaging.

plot() → None

Plot the characteristic in matplotlib.

sort() → None

Sort the characteristic by ascending bias.
