python - 带有最初隐藏/静音的图例组的 Bokeh 图

Question

基本上我想要 this ，但是当绘图加载时，一些图例条目已经静音或隐藏，用户单击以显示它们。


我试图寻找 Bokeh 的文档，但找不到我需要的设置。

这段代码可以满足您的需求(在 Bokeh v1.0.4 上测试)。您只需要设置 visible字形渲染器上的属性。

import pandas as pd
from bokeh.palettes import Spectral4
from bokeh.plotting import figure, output_file, show
from bokeh.sampledata.stocks import AAPL, IBM, MSFT, GOOG

p = figure(plot_width = 800, plot_height = 250, x_axis_type = "datetime")
p.title.text = 'Click on legend entries to hide the corresponding lines'

stocks = ["AAPL", "IBM", "MSFT", "GOOG"]
lines = {}
for data, name, color in zip([AAPL, IBM, MSFT, GOOG], stocks, Spectral4):
    df = pd.DataFrame(data)
    df['date'] = pd.to_datetime(df['date'])
    lines[name] = p.line(df['date'], df['close'], line_width = 2, color = color, alpha = 0.8, legend = name)

lines["AAPL"].visible = False

p.legend.location = "top_left"
p.legend.click_policy = "hide"

output_file("interactive_legend.html", title = "interactive_legend.py example")
show(p)

结果:
