visualization.get_barcode_data(psi2tree, *, modes=None, threshold=0.0)

Get data for a barcode chart.

Parameters

Name	Type	Description	Default
psi2tree	`psiclone.psi2tree.Psi2tree`	A computed Psi2tree object.	required
modes	list	Specify types of which barcodes are drawn. - ‘sub’: a sublevelset filtration - ‘sup’: a superlevelset filtration - ‘reeb’: a Reeb graph (default: all of above)	`None`
threshold		Cut-off threshold for barcode length.	`0.0`

Name	Type	Description
barcodes	dict[str, tuple(numpy.ndarray, numpy.ndarray, numpy.ndarray)]	Dictionary that maps modes to corresponding barcode data. Each `barcodes[mode]` consists of `x`, `y0` and `y1` that are used like `plt.bar(x, y1 - y0, bottom=y0)` to draw the barcode plot.
