bar = (    Bar()    .add_xaxis(x_vals)    .add_yaxis("广州门店", [random.randint(10, 100) for _ in range(6)])    .add_yaxis("中山门店", [random.randint(10, 100) for _ in range(6)])    .add_yaxis("深圳门店", [random.randint(10, 100) for _ in range(6)])    .add_yaxis("东莞门店", [random.randint(10, 100) for _ in range(6)])    .set_series_opts(label_opts=opts.LabelOpts(is_show=True, font_size=14),                          markline_opts=opts.MarkLineOpts(data=[opts.MarkLineItem(y=40, name="达标线=40")]))    .set_global_opts(title_opts=opts.TitleOpts(title='实际销售金额', subtitle="QDM"),                     xaxis_opts=opts.AxisOpts(name='商品'),                     yaxis_opts=opts.AxisOpts(name='单位:万元')))# bar.render('柱状图.html')# 或者bar.render_notebook()

渲染效果：

渲染效果：

渲染效果：
