如何使用ECharts和Python接口生成堆叠区域图

pip install echarts-python

from pyecharts import options as optsfrom pyecharts.charts import Line# 创建一个堆叠区域图的实例line = Line()# 设置x轴和y轴的数据x_data = ["周一", "周二", "周三", "周四", "周五", "周六", "周日"]y_data1 = [120, 200, 150, 80, 70, 110, 130]y_data2 = [220, 320, 240, 140, 120, 230, 210]y_data3 = [320, 420, 340, 240, 220, 330, 310]line.add_xaxis(xaxis_data=x_data)line.add_yaxis(    series_name="产品A",    y_axis=y_data1,    stack="stack1",    areastyle_opts=opts.AreaStyleOpts(opacity=0.5),)line.add_yaxis(    series_name="产品B",    y_axis=y_data2,    stack="stack1",    areastyle_opts=opts.AreaStyleOpts(opacity=0.5),)line.add_yaxis(    series_name="产品C",    y_axis=y_data3,    stack="stack1",    areastyle_opts=opts.AreaStyleOpts(opacity=0.5),)# 设置图表的标题和坐标轴line.set_global_opts(    title_opts=opts.TitleOpts(title="堆叠区域图示例"),    xaxis_opts=opts.AxisOpts(type_="category"),    yaxis_opts=opts.AxisOpts(type_="value"),)# 将图表渲染到HTML文件中line.render("stacked_area_chart.html")
