【问题描述】：

我有类似here 的问题。我也试过你的解决方案。但这一次，我有三个痕迹。两张图在同一个图中。第三个是桌子。这是我的代码：

import pandas as pd
import plotly.tools as plotly_tools
import plotly.graph_objs as go
from plotly.subplots import make_subplots

df1 = pd.DataFrame("SALES_DATE" : ["2020-01-01", "2020-02-01", "2020-03-01", "2020-04-01", "2020-05-01", 
                                    "2020-01-01", "2020-02-01", "2020-03-01", "2020-04-01", "2020-05-01", 
                                    "2020-01-01", "2020-02-01", "2020-03-01", "2020-04-01", "2020-05-01"],
                    "y" : [12, 10, 11, np.nan, np.nan, 12, 10, 11, np.nan, np.nan, 12, 10, 11, np.nan, np.nan],
                    "y_hat" : [np.nan, np.nan, np.nan, 10, 12, np.nan, np.nan, np.nan, 10, 12, np.nan, np.nan, np.nan, 10, 12],

                   )

df2 = pd.DataFrame("ITEM_ID": ["32_2_1004", "32_2_1005", "32_2_1006"],
                   "PREDICTION_ERROR": [2, 1, 0],
                   "PREDICTION": [22, 23, 24])

item_list = ["32_2_1004", "32_2_1005", "32_2_1006"]

def make_multi_plot(df1, df2, item_list):
    
    date_time = str(datetime.datetime.now())[0:16].replace(':','-').replace(' ','_')
    
    with open('Model_Raporu_'+date_time+'.html', 'a') as f:

            trace2 = go.Table(    
                header = dict(
                values = df2[df2.ITEM_ID.isin([item_id])].columns.tolist(),

                align = "left"
                )
            )
            fig.append_trace(trace2,2,1)
        
        Ld = len(fig.data)
        Lc = len(item_list)
        for k in range(3, Ld):
            fig.update_traces(visible=False, selector = k)
    
        def create_layout_button(k, item_id):
            
            visibility= [False]*3*Lc
            for tr in [3*k, 3*k+1]:
                visibility[tr] =True
            return dict(label = item_id,
                        method = 'restyle',

                                 'showlegend': True])    
    

        fig.update_layout(
           updatemenus=[go.layout.Updatemenu(
           active = 0,
           buttons = [create_layout_button(k, item_id) for k, item_id in enumerate(item_list)],
           x = 0.5,
           y = 1.15
           )
        ],
           title = 'Model Raporu',
           template = 'plotly_dark',
           height=800
       )
    
        fig.show()
        f.write(fig.to_html(full_html=False, include_plotlyjs='cdn'))

make_subplots(df1=df1, df2=df2, item_list=item_list)

更改下拉按钮时，只有上图会发生变化。但表保持不变。我无法通过下拉菜单更改它。这是图片：

report

如何使用下拉菜单更改表格？

【问题讨论】：

创建最小的工作代码，我们可以简单地复制和运行。

我刚刚添加了一个工作代码。一个示例数据集。

最后一行应该是make_multi_plot而不是make_subplots。你忘了import numpy as np, import datetime

更简单的date_time = datetime.datetime.now().strftime('%Y-%m-%d_%H-%M')

当我运行此代码并在下拉列表中选择时，它不会更改绘图或表格。

【参考方案1】：

如果您使用print() 查看变量中的值，那么对于visibility，您应该会看到

[True, True, False, False, False, False, False, False, False]
[False, False, False, True, True, False, False, False, False]
[False, False, False, False, False, False, True, True, False]

所以每个列表只有 2 个 True 但他们应该有 3 个 True

你创建了错误的列表visibility - 你必须添加3*k+2

for tr in [3*k, 3*k+1, 3*k+2]:
    visibility[tr] = True

完整的工作代码。

当我使用dropdown 时，我更改了df 中的一些值以查看不同的情节。

非常感谢您的解决方案。它对我有用，我现在理解逻辑。如果你来土耳其，我会给你买咖啡。 :)
