使用pyecharts模块的timeline可按照近10年的时间线轮播2个超市7种水果的柱状图显示：
from pyecharts import options as opts
from pyecharts.charts import Bar, Page, Pie, Timeline
from random import randint
data = {'x': ['草莓', '芒果', '葡萄', '雪梨', '西瓜', '柠檬', '车厘子'],
'沃尔玛': dict(zip(range(2010, 2020), [[randint(100, 1000) for fruit in range(7)] for year in range(10)])),
'家乐福': dict(zip(range(2010, 2020), [[randint(100, 1000) for fruit in range(7)] for year in range(10)]))
}
print(data)
def timeline_bar() -> Timeline:
x = data['x']
tl = Timeline()
for i in range(2010, 2020):
bar = (
Bar()
.add_xaxis(x)
.add_yaxis('沃尔玛', data['沃尔玛'][i])
.add_yaxis('家乐福', data['家乐福'][i])
.set_global_opts(title_opts=opts.TitleOpts("{}年营业额".format(i)))
)
tl.add(bar, "{}年".format(i))
return tl
timeline_bar().render("./img/timeline_bar.html")
