pyecharts怎样配置支持报表图片下载

想要实现的目标，就是图表可以下载图片：

配置方法：

from pyecharts import options as opts
from pyecharts.charts import Bar
from pyecharts.faker import Faker

c = (
    Bar()
    .add_xaxis(Faker.choose())
    .add_yaxis("商家A", Faker.values())
    .add_yaxis("商家B", Faker.values())
)

toolbox_opts=opts.global_options.ToolBoxFeatureOpts(
    save_as_image = {"show": True, "title": "save as image", "type": "png"})

c.set_global_opts(
    title_opts=opts.TitleOpts(title="Bar-基本示例", subtitle="我是副标题"),
    toolbox_opts=opts.ToolboxOpts(feature=toolbox_opts)
)

c.render_notebook()

这个技能很有用
