$name和@$name在进行任何其他文本操作之前先被评估，因此这就是上述方法行不通的原因。您将需要使用CustomJSHover来完成类似的工作

custom = CustomJSHover(args=dict(source=source),code="""
    // use special_vars.name and use special_vars.indices to index in 
    // to the right column of source.data
""")

这是bigreddot使用CustomJSHover建议的实现（适用于Bokeh v1.3.0）：

from bokeh.core.properties import value
from bokeh.models import ColumnDataSource,CustomJSHover
from bokeh.plotting import figure,show

fruits = ['Apples','Pears','Nectarines','Plums','Grapes','Strawberries']
years = ["2015","2016","2017"]
colors = ["#c9d9d3","#718dbf","#e84d60"]

data = {'fruits' : fruits,'2015'   : [2,1,4,3,2,4],'2016'   : [5,6],'2017'   : [3,5,3]}

source = ColumnDataSource(data=data)

tooltips= [("name","$name"),("count","@$name")]

p = figure(x_range=fruits,plot_height=350,title="Fruit Counts by Year",toolbar_location=None,tooltips=tooltips)

renderers = p.vbar_stack(years,x='fruits',width=0.9,color=colors,source=source,legend=[value(x) for x in years],name=years)

p.hover[0].tooltips.append(('info','$name{custom}'))
p.hover[0].formatters = {'$name' : CustomJSHover(code = "return special_vars.name + '_text'")}

show(p)

再多花点功夫，就可以使用CustomJS回调（Bokeh v1.3.0）实现相同的目标：

from bokeh.core.properties import value
from bokeh.models import ColumnDataSource,HoverTool,CustomJS
from bokeh.plotting import figure,3]}

source = ColumnDataSource(data=data)

p = figure(x_range=fruits,tools="")

renderers = p.vbar_stack(years,name=years)

hover_code = "if (cb_data.index.indices.length > 0) { cb_obj.tooltips[2] = ['info',cb_obj.name + '_text'] }"

for renderer in renderers:
    p.add_tools (HoverTool(tooltips=[("name","@$name"),("info","@info"),],renderers=[renderer],name = renderer.name,callback = CustomJS(code = hover_code)))
show(p)
