前言：用pyecharts v1.x版本来绘制水球图。

注：Ppyecharts分为 v0.5.x 和 v1.x 两个大版本，v0.5.x 和 v1.x 间不兼容，v0.5.x是基于Python2.7+、3.4+版本开发的，而v1.x是一个全新的版本，它是基于Python3.6+版本开发的，另外经PyEcharts开发团队决定，0.5.x 版本将不再进行维护。

前提：

# 安装pyecharts模块，直接安装就是最新的版本

pip install pyecharts

#导包

from pyecharts import options as opts

from pyecharts.charts import Liquid

水球图数据很简单，就是一个完成率数字，所以不用定义或导入，也无需做转换。

接下来就可以绘制水球图了：

from pyecharts import options as opts

from pyecharts.charts import Liquid

c = (

#创建水球图对象

Liquid()

#设置数据系列名称及数据，is_outline_show是设置边框线，根据自身喜欢选择

.add("达成率", [0.66], is_outline_show = False)

# 设置图表标题及位置

.set_global_opts(title_opts = opts.TitleOpts(title = "蔬菜部门销售达成率",pos_left = "center"))

#通过render()方法将水球图渲染为html

# .render("圆形水球图.html")

)

c.render_notebook()

水球图的颜色可以设置，只需要add()中添加color参数，代码如下：

from pyecharts import options as opts

from pyecharts.charts import Liquid

c = (

Liquid()

.add("达成率", [0.88], is_outline_show = False, color = ['#DC143C'])

.set_global_opts(title_opts = opts.TitleOpts(title = "水果部门销售达成率",pos_left = "center"))

# .render("圆形水球图.html")

)

c.render_notebook()

红色的水球：

水球的形状也可以自定义：

from pyecharts import options as opts

from pyecharts.charts import Liquid

from pyecharts.globals import SymbolType

c = (

Liquid()

.add("达成率", [0.777], is_outline_show = False, shape = SymbolType.RECT)

.set_global_opts(title_opts = opts.TitleOpts(title = "水产销售达成率",pos_left = "center"))

# .render("矩形水球图.html")

)

c.render_notebook()

矩形水球：

from pyecharts import options as opts

from pyecharts.charts import Liquid

from pyecharts.globals import SymbolType

c = (

Liquid()

.add("达成率", [0.90], is_outline_show = False, shape = SymbolType.DIAMOND)

.set_global_opts(title_opts = opts.TitleOpts(title = "综合部门销售达成率",pos_left = "center"))

# .render("矩形水球图.html")

)

c.render_notebook()

看出区别了吗？只要在add()中添加shape=SymbolType.RECT的设置，同时需要导入对应的模块：from pyecharts.globals import SymbolType

另外shape=SymbolType.DIAMOND就是钻石水球图

from pyecharts import options as opts

from pyecharts.charts import Liquid

from pyecharts.globals import SymbolType

c = (

Liquid()

.add("达成率", [0.60], is_outline_show = False, shape = SymbolType.ROUND_RECT)

.set_global_opts(title_opts = opts.TitleOpts(title = "电商部门销售达成率",pos_left = "center"))

# .render("矩形水球图.html")

)

c.render_notebook()

shape=SymbolType.ROUND_RECT就是圆角矩形水球图

from pyecharts import options as opts

from pyecharts.charts import Liquid

from pyecharts.globals import SymbolType

c = (

Liquid()

.add("达成率", [0.67], is_outline_show = False, shape = SymbolType.TRIANGLE)

.set_global_opts(title_opts = opts.TitleOpts(title = "猪肉部门销售达成率",pos_left = "center"))

# .render("矩形水球图.html")

)

c.render_notebook()

shape=SymbolType.TRIANGLE就是三角形水球图

from pyecharts import options as opts

from pyecharts.charts import Liquid

from pyecharts.globals import SymbolType

c = (

Liquid()

.add("达成率", [0.56], is_outline_show = False, shape = SymbolType.ARROW)

.set_global_opts(title_opts = opts.TitleOpts(title = "物料部门销售达成率",pos_left = "center"))

# .render("矩形水球图.html")

)

c.render_notebook()

shape=SymbolType.ARROW就是箭头水球图

制作水球图不是很简单的吗(?_?)
