PlotManager.plot(x: ArrayLike, y: ArrayLike | None = None, ax: Axes | list[Axes] | int | None = None, **kwargs: Unpack[PlotKwargs]) None[source]#

Creation of a 1D function plot (or a 1D slice plot).

This function plots a 1D function or a 1D slice. It creates a simple figure and a single axis if none are given prior. If a single function argument is given, it plots the graph of that function using a linear variable as x parameter. However, if a pair of arrays is provided, it plots the second as a function of the first one.

Parameters:
- alpha: float, default 1.0

Sets the opacity of the plot, where 1.0 is fully opaque and 0.0 is fully transparent.

- aspect: ‘auto’ | ‘equal’ | float, default ‘auto’

Sets the aspect ratio of the plot. The ‘auto’ keyword is the default option. The ‘equal’ keyword sets the same scaling for x and y. A float fixes the ratio between the y-scale and the x-scale (1.0 is the same as ‘equal’).

- ax: ax | int | None, default None

The axis where to plot. If None, the last considered axis will be used.

- bottom: float, default varies

The bottom limit of the axis / axes set. For the figure layout it is the space from the bottom border to the plot (default 0.1); for an inset zoom it is the bottom position of the inset (default 0.6 + height).

- c: str, default self.color

Determines the color. If not defined, the program will loop over an array of 6 colors which are different for the most common vision deficiencies.

- edgecolor: list[str], default [None]

Sets the edge color of the legend. The default value is black (‘k’).

- figsize: list[float], default varies

Sets the figure size. The default is [6*sqrt(ncol), 5*sqrt(nrow)], computed from the number of rows and columns (or [8,5] for a single plot).

- fillstyle: {‘full’, ‘left’, ‘right’, ‘bottom’, ‘top’, ‘none’},

default ‘full’ Sets the marker filling. The default value is the fully filled marker (‘full’).

- fontsize: float, default 17.0

Sets the fontsize for all the axis components.

- grid: bool | string, default False

Enables/disables the grid on the plot. If True it enables both axes grids. If ‘x’ or ‘y’ it enables only the x- or y-axis grid.

- hratio: [float], default [1.0]

Ratio between the rows of the plot. The default is that every plot row has the same height.

- hspace: [float], default []

The space between plot rows (in figure units). If not enough or too many spaces are considered, the program will remove the excess and fill the lacks with [0.1].

- label: str, default None

Associates a label to the plot, used for the creation of the legend.

- labelsize: float, default fontsize

Sets the labels fontsize (which is the same for both labels). The default value corresponds to the value of the keyword ‘fontsize’.

- left: float, default varies

The left limit of the axis / axes set. For the figure layout it is the space from the left border to the plot (default 0.125); for an inset zoom it is the left position of the inset (default 0.6).

- legalpha: float, default 0.8

Sets the opacity of the legend.

- legcols: int, default 1

Sets the number of columns that the legend should have.

- legpad: float, default 0.8

Sets the space between the lines (or symbols) and the corresponding text in the legend.

- legpos: int | str, default None

If defined, creates a legend at the specified location.

- legsize: float, default fontsize

Sets the fontsize of the legend. The default value is the default fontsize value.

- legspace: float, default 2

Sets the space between the legend columns, in font-size units.

- ls: {‘-’, ‘–’, ‘-.’, ‘:’, ‘ ‘, etc.}, default ‘-’

Sets the linestyle. The choices available are the ones defined in the matplotlib package.

- lw: float, default 1.3

Sets the linewidth.

- marker: {‘o’, ‘v’, ‘^’, ‘<’, ‘>’, ‘X’, ‘ ‘, etc.}, default ‘ ‘

Sets an optional symbol for every point. The default value is no marker (’ ‘).

- minorticks: str, default None

If not None enables the minor ticks on the plot (for both grid axes).

- ms: float, default 3

Sets the marker size.

- mscale: float, default 1.0

Sets the marker scale. The default value is 1.0.

- ncol: int, default 1

The number of columns of subplots.

- nrow: int, default 1

The number of rows of subplots.

- proj: str, default None

Custom projection for the plot (e.g. 3D). Recommended only if needed. WARNING: pyPLUTO does not support 3D plotting for now, only 3D axes. The 3D plot feature will be available in future releases.

- right: float, default varies

The right limit of the axis / axes set. For the figure layout it is the space from the right border to the plot (default 0.9); for an inset zoom it is the right position of the inset (default left + 0.15).

- sharex: bool | str | Matplotlib axis, default False

Enables/disables the sharing of the x-axis between the subplots.

- sharey: bool | str | Matplotlib axis, default False

Enables/disables the sharing of the y-axis between the subplots.

- suptitle: str, default None

Creates a figure title over all the subplots.

- ticksdir: {‘in’, ‘out’}, default ‘in’

Sets the ticks direction. The default option is ‘in’.

- tickssize: float | bool, default True

Sets the ticks fontsize (which is the same for both grid axes). The default value corresponds to the value of the keyword ‘fontsize’.

- tight: bool, default True

Enables/disables tight layout options for the figure. In case of a highly customized plot (e.g. ratios or space between rows and columns) the option is set by default to False since that option would not be available for standard matplotlib functions.

- title: str, default None

Places the title of the plot on top of it.

- titlepad: float, default 8.0

Sets the distance between the title and the top of the plot.

- titlesize: float, default fontsize

Sets the title fontsize. The default value corresponds to the value of the keyword ‘fontsize’.

- top: float, default varies

The top limit of the axis / axes set. For the figure layout it is the space from the top border to the plot (default 0.9); for an inset zoom it is the top position of the inset (default bottom + height).

- wratio: [float], default [1.0]

Ratio between the columns of the plot. The default is that every plot column has the same width.

- wspace: [float], default []

The space between plot columns (in figure units). If not enough or too many spaces are considered, the program will remove the excess and fill the lacks with [0.1].

- x (not optional): 1D array

This is the x-axis variable. If y is not defined, then this becomes the y-axis variable.

- xlabelpad: float, default 4.0

The padding between the x-axis label and the axis.

- xrange: [float, float], default ‘Default’

Sets the range in the x-direction. If not defined, the range is computed automatically from the x-array.

- xscale: {‘linear’,’log’}, default ‘linear’

If enabled (and different from ‘Default’), sets automatically the scale on the x-axis. Data in log scale should be used with the keyword ‘log’, while data in linear scale should be used with the keyword ‘linear’.

- xticks: list[float] | None | bool, default True

If enabled (and different from True), sets manually ticks on the x-axis. In order to completely remove the ticks the keyword should be used with None.

- xtickslabels: list[str] | None | bool, default True

If enabled (and different from True), sets manually the ticks labels on the x-axis. In order to completely remove the ticks the keyword should be used with None. Note that fixed tickslabels should always correspond to fixed ticks.
