如何在bokeh烛台图（python）中添加悬停工具

Question

我的代码

from bokeh.plotting import figure,show,output_file
from bokeh.models import HoverTool,ColumnDataSource

def make_a_plot(data,company_name):
    p=figure(x_axis_type="datetime",aspect_ratio= 16/9)
    p.sizing_mode = 'scale_height'
    data["Middle"]=(data.Open+data.Close)/2
    data["Height"]=abs(data.Close+data.Open)
    df1=data[data.Close > data.Open]    
    df2=data[data.Close < data.Open]   
    p.segment(data.index, data.High ,data.index, data.Low, color="black")  
    hours_12 = 12*60*60*1000
    p.rect(df1.index,(df1["Open"]+df1["Close"])/2,hours_12,abs(df1["Open"]-df1["Close"]),fill_color="#CCFFFF",line_color="black")
    p.rect(df2.index,(df2["Open"]+df2["Close"])/2,hours_12,abs(df2["Open"]-df2["Close"]),fill_color="#FF3333",line_color="black")
    output_file("Get info on bse companies/bse stock info/bse_analysis_of_%s.html"%company_name,title="%s | Candle stick chart"%company_name)
    show(p)


def get_locs_equal(data):
    data["Status"]=[inc_dec(c, o) for c, o in zip(data.Close, data.Open)]
    lst = ["Equal","Equal"]
    equal = data[data.Status.isin(lst)]
    return equal


def inc_dec(c, o):
    if c > o:
        value= "Increase"
    elif c < o:
        value="Decrease"
    else:
        value = "Equal"

    return value

数据输入将类似于

^{tb1}$
