Name	Value	Default	Description
`ymax`	float	0.2	Maximum value of the y-axis in the energy plots of RS, EA, and EA-vc (binary systems).
`markersize`	int	10	Size of markers in all energy plots.
`fig_format`	str	`svg`	Figure formats: `svg`, `png`, or `pdf`.

EA

See also CrySPY > Tutorial > Evolutionary Algorithm (EA) > Analysis and visualization.

Name	Value	Default	Description
`ref_gen`	int	`None`	[post-analysis only] Reference generation for plotting. When specified, the plot is generated as of the end of this generation. If not specified, the latest generation is used. Must satisfy `plot_max_gen` <= `ref_gen`.
`plot_min_gen`	int	`None`	[post-analysis only] Minimum generation for plotting. If not specified (i.e., None), the value is treated as 1.
`plot_max_gen`	int	`None`	[post-analysis only] Maximum generation for plotting. If omitted, plotting extends through `ref_gen` when specified; otherwise, it extends through the latest generation.

EA-vc

See also CrySPY > Tutorial > Variable-composition evolutionary algorithm (EA-vc) > Analysis and visualization for the convex hull plot.

Name	Value	Default	Description
`show_max`	float	`None`	Maximum hull distance shown in ternary systems.
`label_stable`	bool	`True`	Whether or not to show stable compositions in the plot.
`vmax`	float	0.2	Maximum value of the colorbar for the hull distance.
`bottom_margin`	float	0.04	Bottom margin of the y-axis in binary systems.
`axis_order`	str	`None`	Specifies the axis order: `lr` or `rl` in binary systems, and permutations of `tlr` (`lrt`, `rtl`, …) in ternary systems. When `terminals` is used, specify the axis order with `terminal_axis_order`.
`ref_gen`	int	`None`	[post-analysis only] Reference generation for plotting. When specified, the plot is generated as of the end of this generation. If not specified, the latest generation is used. Must satisfy `plot_max_gen` <= `ref_gen`.
`plot_min_gen`	int	`None`	[post-analysis only] Minimum generation for plotting. If not specified (i.e., None), the value is treated as 1.
`plot_max_gen`	int	`None`	[post-analysis only] Maximum generation for plotting. If omitted, plotting extends through `ref_gen` when specified; otherwise, it extends through the latest generation.
`show_comp_window`	bool	`True`	Whether to show the allowed composition range on the convex hull plot.
`ref_gen_comp`	int	`None`	[post-analysis only] Generation from which `min_comp` and `max_comp` are taken for the composition-window overlay. If omitted, `ref_gen` is used when specified; otherwise, the latest generation is used.
`terminals`	str str [str]	`None`	[post-analysis only] Two or three terminal compositions that define the compound phase diagram in `cryspy-Eplot` (e.g., `Li2O Al2O3`). Each terminal composition must have an entry in the phase-diagram data.
`terminal_axis_order`	str	`None`	[post-analysis only] Axis order used with `terminals`. Each letter gives the position of the corresponding terminal in the order specified by `terminals` (`t`: top, `l`: left, `r`: right). Use `lr` or `rl` for two terminals, or a permutation of `tlr` (`lrt`, `rtl`, …) for three terminals. If omitted, `lr` is used for two terminals and `tlr` for three.
