marsilea.plotter.AnnoLabels

class marsilea.plotter.AnnoLabels(labels, mark=None, text_pad=0.5, text_gap=0.5, pointer_size=0.5, linewidth=None, connectionstyle=None, relpos=None, armA=None, armB=None, **options)

Bases: _LabelBase

Annotate a few rows or columns

This is useful when your heatmap contains many rows/columns, and you only want to annotate a few of them.

Parameters:

labelslist, np.ma.MaskedArray

The length of the labels should match the main canvas side where it attaches to, the labels that won’t be displayed should be masked.

marklist

If your labels is not a mask array, this will help you mark the labels that you want to draw

sidestr

text_padfloat

Add extra space and the start and end of the label

text_gapfloat

Add extra spacing between the labels, relative to the fontsize

pointer_sizefloat

The size of the pointer in inches

linewidthfloat

The linewidth of the pointer

connectionstyle

relpos2-tuple

armA, armBfloat

options

Pass to matplotlib.text.Text

Examples

>>> labels = np.arange(100)

>>> import marsilea as ma
>>> from marsilea.plotter import AnnoLabels
>>> matrix = np.random.randn(100, 10)
>>> h = ma.Heatmap(matrix)
>>> marks = AnnoLabels(labels, mark=[3, 4, 5, 96, 97, 98])
>>> h.add_right(marks)
>>> h.render()
