如何使用Bokeh和Pandas繪制帶有分類數據的散點圖？

Question

我有一個包含數據的Pandas DataFrame：

Merchant | Non-Merchant | Num of Chats Received | Num of Chats Made
1        | 0            | 80                    | 50
0        | 1            | 60                    | 30
1        | 0            | 70                    | 40
0        | 1            | 50                    | 20

我希望能夠在散點圖上繪制兩種不同類型的用戶（商家，非商家），比較[收到的聊天數，y軸]。

在上面的數據中，

商家是商家專欄中標有“1”的商家

非商家是Merchants列中標記為'1'的商家，

它是二進制的，沒有[1,1]。

我一般都是Bokeh和Data Viz的新手，假設Bokeh是我的首選方法，我應該怎么做呢？

這是用散景做的一種方法

碼：

from bokeh.plotting import figure, output_file, show
import pandas as pd

data = {'Merchant':[1,0,1,0],
        'Non-Merchant':[0,1,0,1],
        'Num of Chats Received':[80,60,70,50],
        'Num of Chats Made':[50,30,40,20]}

df = pd.DataFrame(data)

merchant_chats_made = list(df[df['Merchant'] == 1]['Num of Chats Made'])
merchant_chats_received = list(df[df['Merchant'] == 1]['Num of Chats Received'])
non_merchant_chats_made = list(df[df['Non-Merchant'] == 1]['Num of Chats Made'])
non_merchant_chats_received = list(df[df['Non-Merchant'] == 1]['Num of Chats Received'])

output_file('merchant.html')

p = figure(plot_width=400, plot_height=400)
p.circle(merchant_chats_made,
         merchant_chats_received,
         size=10,color='red',alpha=0.5,
         legend='Merchant')

p.circle(non_merchant_chats_made,
         non_merchant_chats_received,
         size=10,color='blue',alpha=0.5,
         legend='Non-Merchant')

p.xaxis.axis_label = 'Chats Made'
p.yaxis.axis_label = 'Chats Received'
p.legend.location = 'top_left'

show(p)
