import plotly.graph_objects as go
import numpy as np

y0 = np.random.randn(50)
y1 = np.random.randn(50) + 1 # shift mean
y2 = np.random.randn(50) + 2

fig = go.Figure()
fig.add_trace(go.Box(y=y0, name='Sample A',
                marker_color = 'indianred'))
fig.add_trace(go.Box(y=y1, name = 'Sample B',
                marker_color = 'lightseagreen'))

fig.show()
