将Bokeh Glyph变成链接

问题描述

我想将某个绘图上的所有Bokeh字形都转换成指向其他页面的链接.这可能吗?

I would like to turn all of the Bokeh glyphs on a certain plot into links to other pages. Is this possible?

例如，如果我有一张国家/地区地图，则每个国家/地区都是一个补丁，如果用户单击某个国家/地区，我希望将其重定向到该维基百科页面.

For example if I had a map of countries, each country as a patch, if a user were to click on a country I would like to redirect them to that wikipedia page.

推荐答案

用户指南:

from bokeh.models import ColumnDataSource, OpenURL, TapTool
from bokeh.plotting import figure, output_file, show

output_file("openurl.html")

p = figure(plot_width=400, plot_height=400,
           tools="tap", title="Click the Dots")

source = ColumnDataSource(data=dict(
    x=[1, 2, 3, 4, 5],
    y=[2, 5, 8, 2, 7],
    color=["navy", "orange", "olive", "firebrick", "gold"]
    ))

p.circle('x', 'y', color='color', size=20, source=source)

url = "http://www.colors.commutercreative.com/@color/"
taptool = p.select(type=TapTool)
taptool.callback = OpenURL(url=url)

show(p)
