.set_global_opts(title_opts) 設置標題

使用 options 配置項，在 pyecharts 中，一切皆 Options。

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

# V1 版本開始支持鏈式調用
# 你所看到的格式其實是 `black` 格式化以后的效果
# 可以執行 `pip install black` 下載使用
bar = (
    Bar()
    .add_xaxis(["襯衫", "羊毛衫", "雪紡衫", "褲子", "高跟鞋", "襪子"])
    .add_yaxis("商家A", [5, 20, 36, 10, 75, 90])
    .set_global_opts(title_opts=opts.TitleOpts(title="主標題", subtitle="副標題"))
    
	# 或者直接使用字典參數
    # .set_global_opts(title_opts={"text": "主標題", "subtext": "副標題"})
)
bar.render()
