考虑到您的站点有两个22系列图表和两个16系列图表，粗略的解决方案是：

from selenium import webdriver
import time
import pandas as pd

driver = webdriver.Chrome()

website = "https://rspo.org/palmtrace"

driver.get(website)
time.sleep(2)

my_data = []

for chart in range(2):
    for series in range(22):
        temp = driver.execute_script('return window.Highcharts.charts[{}]'
                                '.series[{}].options.data'.format(chart,series))
        temp.insert(0, driver.execute_script('return window.Highcharts.charts[{}]'
                                '.series[{}].options.name'.format(chart,series)))
        my_data.append(temp)

for chart in range(2,4):
    for series in range(16):
        temp = driver.execute_script('return window.Highcharts.charts[{}]'
                                '.series[{}].options.data'.format(chart,series))
        temp.insert(0, driver.execute_script('return window.Highcharts.charts[{}]'
                                '.series[{}].options.name'.format(chart,series)))
        my_data.append(temp)

df = pd.DataFrame(my_data)
print(df)
