lets_plot.position_jitter

lets_plot.position_jitter(width=None, height=None, seed=None)

Adjust position by assigning random noise to points. Better for discrete values.

Parameters:

widthfloat

Jittering width. The value of width is relative and typically ranges between 0 and 0.5. Values that are greater than 0.5 lead to overlapping of the points.

heightfloat

Jittering height. The value of height is relative and typically ranges between 0 and 0.5. Values that are greater than 0.5 lead to overlapping of the points.

seedint

A random seed to make the jitter reproducible. If None (the default value), the seed is initialised with a random value.

Returns:

FeatureSpec

Geom object position specification.

Notes

Adjust position by dodging overlaps to the side.

Examples

import numpy as np
from lets_plot import *
LetsPlot.setup_html()
n = 100
np.random.seed(42)
x = np.random.randint(4, size=n)
y = np.random.randint(3, size=n)
c = np.char.add(x.astype(str), y.astype(str))
ggplot({'x': x, 'y': y, 'c': c}, aes('x', 'y')) + \
    geom_point(aes(fill='c'), show_legend=False, \
               size=8, alpha=.5, shape=21, color='black', \
               position=position_jitter(width=.2, height=.2, seed=42))
