编辑：这现在内置到bokeh中，请参阅文档：

和

也许有点晚了，但我今天也想这样做。
import numpy as np
from bokeh.plotting import figure, show, output_file
# some pseudo data
xs = np.linspace(0, 2*np.pi, 25)
yerrs = np.random.uniform(0.1, 0.3, xs.shape)
ys = np.sin(xs) + np.random.normal(0, yerrs, xs.shape)
output_file('bokeh_errorbars.html')
# plot the points
p = figure(title='errorbars with bokeh', width=800, height=400)
p.xaxis.axis_label = 'x'
p.yaxis.axis_label = 'y'
p.circle(xs, ys, color='red', size=5, line_alpha=0)
# create the coordinates for the errorbars
err_xs = []
err_ys = []
for x, y, yerr in zip(xs, ys, yerrs):
err_xs.append((x, x))
err_ys.append((y - yerr, y + yerr))
# plot them
p.multi_line(err_xs, err_ys, color='red')
show(p)
结果如下：
可能需要将其用作这样的功能：
def errorbar(fig, x, y, xerr=None, yerr=None, color='red',
point_kwargs={}, error_kwargs={}):
fig.circle(x, y, color=color, **point_kwargs)
if xerr:
x_err_x = []
x_err_y = []
for px, py, err in zip(x, y, xerr):
x_err_x.append((px - err, px + err))
x_err_y.append((py, py))
fig.multi_line(x_err_x, x_err_y, color=color, **error_kwargs)
if yerr:
y_err_x = []
y_err_y = []
for px, py, err in zip(x, y, yerr):
y_err_x.append((px, px))
y_err_y.append((py - err, py + err))
fig.multi_line(y_err_x, y_err_y, color=color, **error_kwargs)
