最初的答案是古老且过时的，这是如何使用任何现代版本的bokeh来实现此目的：
from bokeh.plotting import figure, show
import numpy as np
x = np.linspace(0, 2*np.pi)
y1 = np.sin(x)
y2 = np.cos(x)
fig = figure(tools="reset", tooltips=[("x", "$x"), ("y", "$y")])
s1 = fig.scatter(x, y1, color='#0000ff', size=10, legend_label='sine')
s2 = fig.scatter(x, y2, color='#ff0000', size=10, legend_label='cosine')
show(fig)
