如何在一个 plot 中使用不同范围的 plot 数据框的特定列（也许使用子图？）

Question

I have a data frame that has parameters with different ranges. You can see the sample data below:

Since the range of parameters are different if I plot a boxplot for these variables, the result won't look good. I searched and I found this link How to plot boxplots of multiple columns with different ranges which explains plotting using `plotly. Here is my code following this link

from plotly.subplots import make_subplots
import plotly.graph_objects as go
vars = ['Current_Market_Cap', 'Last_Price', 'Alpha', "Beta"]
fig = make_subplots(rows=1, cols=len(vars))
for i, var in enumerate(vars):
    fig.add_trace(
        go.Box(y=f_df[var],
        name=var),
        row=1, col=i+1
    )

fig.update_traces(boxpoints='all', jitter=.3)

The result of this code is shown below:

however, I don't want the interactive mode and what I really need is a simple boxplot for each variable side by side. Basically, I want the same output of plotly but not really fancy and interactive and just with basic python code

is there anyway doing that? maybe using subplot instead?

If you need to use matplotlib to create the above multi-range graphs, as you mentioned, you can use subplots like this. Note that I have used random numbers and so, no outliers. But, the colors should remain the same for the outliers as well.

import numpy as np
import matplotlib.pyplot as plt
df = pd.DataFrame(
    {'Current_Market_Cap': np.random.rand(100)*1000000,
     'Last_Price': np.random.rand(100)*100,
     'Alpha': np.random.rand(100),
     'Beta': np.random.rand(100)*10
    })

fig, axs = plt.subplots(1, len(df.columns), figsize=(20,10))
mycolors = ['r', 'b', 'c', 'k']
for i, ax in enumerate(axs.flat):
    ax1 = ax.boxplot(df.iloc[:,i])
    ax.set_title(df.columns[i], fontsize=20, fontweight='bold')
    ax.tick_params(axis='y', labelsize=14)
    for item in ['boxes', 'whiskers', 'fliers', 'medians', 'caps']:
        plt.setp(ax1[item], color=mycolors[i])
    
plt.tight_layout()

Output
