下面是一个示例，说明如何使用scrapy-playwright来提取所需的数据：

import scrapy
headers = {
    'authority': 'api.twitch.tv',
    'accept': '*/*',
    'accept-language': 'en-GB,en-US;q=0.9,en;q=0.8',
    'authorization': 'Bearer a4xqvkgns8duyuudnnr3pmo5mjxl36',
    'client-id': '2eji4dzts0ppwwpprxwnao9d27sfwz',
    'origin': 'https://twitchtracker.com',
    'referer': 'https://twitchtracker.com/',
    'sec-ch-ua': '".Not/A)Brand";v="99", "Google Chrome";v="103", "Chromium";v="103"',
    'sec-ch-ua-mobile': '?0',
    'sec-ch-ua-platform': '"macOS"',
    'sec-fetch-dest': 'empty',
    'sec-fetch-mode': 'cors',
    'sec-fetch-site': 'cross-site',
    'user-agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.0.0 Safari/537.36',
}
class twitchSpider(scrapy.Spider):
    name = 'twitch'
    start_urls = ['https://twitchtracker.com/games/32982']
    def start_requests(self):
        for url in self.start_urls:
            yield scrapy.Request(
                url,
                headers=headers,
                callback = self.parse,
                meta = {
                    'playwright':True
                }
            )
    def parse(self,response):
        from collections import defaultdict
        values = response.xpath("(.//*[name()='g'][@class='highcharts-series-group'])[1]//*[name()='g']//*//@d").getall()
        class_values = response.xpath("(.//*[name()='g'][@class='highcharts-series-group'])[1]//*[name()='g']//*//@class").getall()
        chart_dict = defaultdict(list)
        for charts, names in zip(values, class_values):
            #chart_dict[names].append(charts)
            chart_dict['big'].append(charts.split(' ')[1::3])
            chart_dict['small'].append(charts.split(' ')[2::3])
            chart_dict['classes'].append(names)
        yield chart_dict

当我们得到重叠的折线图时，这将抓取不同系列的图表数据。
然后我们提取big或small表示的两个值，剩下的可以通过绘制正确的值来完成。
