Functions

Name	Description
plot_deim_weights	Create a stem plot of xi with a zoomed inset.
plot_ecsw_weights_3d	Visualize ECSW weights on a 3D mesh, fading out near-zero weights.

plot_deim_weights

utils.visualization.plot_utils.plot_deim_weights(
    xi,
    zoom_indices=(0, 1),
    figsize=(12, 3),
    nbins=6,
    line_color='#163e64',
    stem_color='#a6a6a6',
    zoom_loc='upper left',
    zoom_size=('25%', '40%'),
    zoom_title='Zoomed-in view',
    zoom_box_offset_x=-0.5,
    zoom_box_offset_y=-0.2,

    zoom_box_height_scale=0.4,
    zoom_box_color='red',
    zoom_box_linestyle='--',
    zoom_box_linewidth=1.0,
)

Create a stem plot of xi with a zoomed inset. Uses constrained_layout for automatic spacing.

plot_ecsw_weights_3d

utils.visualization.plot_utils.plot_ecsw_weights_3d(
    mesh,
    weights,
    projection='3d',
    plane='xy',
    figsize=(8, 6),
    cmap='viridis',
    zero_color='#eeeeee',
    zero_alpha=0.3,
    weight_threshold=0.001,
)

Visualize ECSW weights on a 3D mesh, fading out near-zero weights.

Parameters

Name	Type	Description	Default
mesh	object	Mesh with attributes: - p: array of shape (3, n_nodes) for node coords. - t: array of shape (nodes_per_elem, n_elems).	required
weights	1D ndarray of length n_elems	ECSW weight per element.	required
projection	'3d' or projected	‘3d’ = scatter in 3D; ‘projected’ = heatmap on a plane.	'3d'
plane	'xy', 'xz', or 'yz'	which plane to project onto if projected.	'xy'
figsize	figure size.		(8, 6)
cmap	name of colormap for >threshold weights.		'viridis'
zero_color	color for weights ≤ threshold.		'#eeeeee'
zero_alpha	alpha for zero_color points.		0.3
weight_threshold	float	any w ≤ this will be considered “zero” for display.	0.001
