`plotter.drawables.functions`¶

class `FunctionPlot(Drawable)`¶

Class for creating a plot of a mathematical function to be drawn on a canvas.

Attributes:

Name	Type	Description
`x`	NArray1D[Any]	The domain over which the function `f` is evaluated.
`f`	Callable[[NArray1D[Any]], NArray1D[Any]]	The function that defines the plot.
`wider`	tuple[float, float], optional	The percentages (left, right) to which the domain `x` is to be widened. Defaults to `(0, 0)`.
`dens`	int, optional	The density factor to be passed to `_make_wider()`. Defaults to 1.
`y`	NArray1D[Any] or None	The values of `f` evaluated on the (possibly widened) domain, populated after `__post_init__` runs.

Defined attributes:

draw(self, canvas: Canvas | ZoomInset, plot_n: int=0, label: str | None=None, **kwargs) -> None

Draws the plot on the canvas.

Args:

Name	Type	Description
`canvas`	Canvas \| ZoomInset	The canvas (or zoom-inset panel) to draw the plot on.
`plot_n`	int, optional	The index of the subplot. Defaults to 0.
`label`	str, optional	The label for the plot in the legend. Defaults to `None`.

Keyword Arguments:

Name	Type	Description
`color`	str	The Matplotlib color of the plot. Defaults to "darkgreen".
`lw`	float	The line width. Defaults to 1.5.
`style`	str	The line style. Defaults to `"-"`.
`alpha`	float	The opacity of the line. Defaults to 1.0.
`inverted`	bool	If `True`, plots the inverse function. Defaults to `False`.
