定义一个更新函数,显示bokeh图中接下来的n个点

你可以改变 x_range :

from bokeh.plotting import figure
from bokeh.io import show, output_notebook
from bokeh.models import Button, CustomJS
from bokeh.layouts import row
from random import random

p = figure(x_range=(0, 10))
p.line(list(range(1000)), [random() for _ in range(1000)])

b = Button(label='Show next 10', callback=CustomJS(args=dict(xr=p.x_range), code="""
    xr.start = xr.end;
    xr.end = xr.end + 10;
"""))
