python编写时间线柱状统计图（可自动播放）

使用的模块为pyecharts，需要提前安装
代码内容如下：

from pyecharts.charts import Bar, Timeline
from pyecharts.options import LabelOpts
from pyecharts.globals import ThemeType

# bar = Bar()
#
# bar.add_xaxis(["America", "China", "Korea"])
#
# bar.add_yaxis("GDP", [30, 50, 64],
#               label_opts = LabelOpts(position= "right"))
#
# bar.reversal_axis()     #翻转X、Y轴
# bar.render("基础图.html")

bar1 = Bar()
bar1.add_xaxis(["America", "China", "Korea"])
bar1.add_yaxis("GDP", [30, 50, 64],
              label_opts = LabelOpts(position= "right"))#控制柱状图数字信息显示在右边
bar1.reversal_axis()     #翻转X、Y轴

bar2 = Bar()
bar2.add_xaxis(["America", "China", "Korea"])
bar2.add_yaxis("GDP", [50, 20, 68],
              label_opts = LabelOpts(position= "right"))
bar2.reversal_axis()     #翻转X、Y轴

bar3 = Bar()
bar3.add_xaxis(["America", "China", "Korea"])
bar3.add_yaxis("GDP", [30, 80, 54],
              label_opts = LabelOpts(position= "right"))
bar3.reversal_axis()     #翻转X、Y轴


timeline = Timeline({"theme": ThemeType.WALDEN})       # {"theme": ThemeType.主题配色可自选}
timeline.add(bar1, "2020" )
timeline.add(bar2, "2021")
timeline.add(bar3, "2022")

# 自动播放
timeline.add_schema(
    play_interval = 1000,        # 播放时间毫秒
    is_timeline_show= True,#是否显示时间线
    is_auto_play=True,#是否自动播放
    is_loop_play=True       # 循环播放
)

timeline.render("timeline_picture.html")
