Question

在以这种方式渲染绘图之后，我似乎无法让HoverTool显示圆形字形的信息（下面的代码）。 hovertool弹出，但每个工具提示显示＆＃39; ???＆＃39;而不是ColumnDataSource中的信息。任何帮助将不胜感激！

from jinja2 import Template

from bokeh.models import HoverTool, ColumnDataSource, BoxSelectTool,             GeoJSONDataSource
from bokeh.core.templates import CSS_RESOURCES, JS_RESOURCES
from bokeh.embed import components
from bokeh.plotting import figure
from bokeh.resources import INLINE
from bokeh.util.string import encode_utf8


source = ColumnDataSource(
    data=dict(
        x=[1, 2, 3, 4, 5],
        y=[2, 5, 8, 2, 7],
        desc=['A', 'b', 'C', 'd', 'E'],
    )
)

hover = HoverTool(

    tooltips=[
        ("index", "$index"),
        ("(x,y)", "($x, $y)"),
        ("desc", "@desc"),
    ]
)

p = figure(plot_width=400, plot_height=400,
       title="Mouse over the dots")

g1 = p.circle('x', 'y', size=20, source=source)

hover = HoverTool(
    renderers= [g1],
    tooltips=[
        ("index", "$index"),
        ("(x,y)", "($x, $y)"),
        ("desc", "@desc"),
    ]
)
p.add_tools(hover)

js_resources = JS_RESOURCES.render(
    js_raw=INLINE.js_raw,
    js_files=INLINE.js_files
)

css_resources = CSS_RESOURCES.render(
    css_raw=INLINE.css_raw,
    css_files=INLINE.css_files
)

script, div = components(p, INLINE)
template = Template('''<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="utf-8">
        <title>Bokeh Scatter Plots</title>
        {{ js_resources }}
        {{ css_resources }}
        {{ script }}
    </head>
    <body>
            {{ div }}
    </body>
</html>
''')
html = template.render(
    js_resources=js_resources,
    css_resources=css_resources,
    script=script,
    div=div
)

filename='toolTipPrac.html'
with open(filename, 'w') as f:
    f.write(html)

HoverTool显示＆＃39; ???＆＃39;在模板渲染后的散景图中
