- FitFromFOTF.create_tangent_curve(x: float, label: str | None = None, color: str = 'default', line_width: float | Literal['default'] = 'default', line_style: str = 'default', copy_first: bool = False) Self #
Creates a new curve which is the tangent to the original curve at a given x value.
- Parameters:
- xfloat
The x value at which the tangent is to be calculated.
- labelstr, optional
Label of the new curve to be displayed in the legend.
- colorstr
Color of the new curve. Default depends on the
figure_style
configuration.- line_widthfloat
Width of the new curve. Default depends on the
figure_style
configuration.- line_stylestr
Style of the new curve. Default depends on the
figure_style
configuration.- copy_firstbool
If
True
, a copy of the curve (with all its parameters) will be returned with the tangent applied. Any other parameters passed to this method will also be applied to the copied curve. IfFalse
, a new curve will be created with the tangent applied and the parameters passed to this method.
- Returns:
