水球图是一种适合于展现单个百分比数据的图表类型，pyecharts模块能够非常方便画出水球图，进而实现酷炫的数据展示效果。

下面给大家介绍一下常见水球图的实现方法：

一、基本水球图

from pyecharts import options as opts
from pyecharts.charts import Liquid
 
c = (
    Liquid()
    .add("lq", [0.6, 0.7])
    .set_global_opts(title_opts=opts.TitleOpts(title="基本形状"))
)
c.render_notebook()

这是最基本的水球图

二、改变水球形状和颜色

from pyecharts import options as opts
from pyecharts.charts import Liquid
from pyecharts.globals import SymbolType
 
c = (
    Liquid()
    .add("lq", [0.3, 0.7], shape=SymbolType.TRIANGLE,
         color=['#4B0082'])
    .set_global_opts(title_opts=opts.TitleOpts(title="Liquid-Shape-rect"))
)
c.render_notebook()

通过设置以下参数，可以变换水球的形状和颜色

color：改变水的颜色，注意，颜色是列表形式 
shape：改变形状，水球外形，有' circle', 'rect', 'roundRect', 'triangle', 'diamond', 'pin', 'arrow' 可选

三、不显示外边框、多波浪

from pyecharts import options as opts
from pyecharts.charts import Liquid
from pyecharts.globals import SymbolType
 
c = (
    Liquid()
    .add("lq",[0.67, 0.30, 0.15], is_outline_show=False)
    .set_global_opts(title_opts=opts.TitleOpts(title="Liquid-Shape-rect"))
)
c.render_notebook()

is_outline_show：控制外边框

四、多个水球图显示

将水球按一定规则摆放在一起，用来展示多个数据指标，将会非常美观

from pyecharts import options as opts
from pyecharts.charts import Grid, Liquid
from pyecharts.commons.utils import JsCode
 
l1 = (
    Liquid()
    .add("lq", [0.6, 0.7], 
         center=["13%", "60%"],
         color=['#3CB371'],
         label_opts=opts.LabelOpts(
         font_size=20,
         formatter=JsCode(
            """function (param) {
                    return ('第一季度：'+Math.floor(param.value * 10000) / 100) + '%';
                }"""
        ),
        position="inside",
    ),)
    .set_global_opts(title_opts=opts.TitleOpts(title="多个 Liquid 显示"))
)
 
l2 = Liquid().add(
    "lq",
    [0.5554],
    center=["38%", "60%"],
    color=['#87CEEB'],
    label_opts=opts.LabelOpts(
        font_size=20,
        formatter=JsCode(
            """function (param) {
                    return ('第二季度：'+Math.floor(param.value * 10000) / 100) + '%';
                }"""
        ),
        position="inside",
    ),
)
 
l3 = (
    Liquid()
    .add("lq", [0.63, 0.7], 
         center=["63%", "60%"],
         color=['#FAFAD2'],
         label_opts=opts.LabelOpts(
         font_size=20,
         formatter=JsCode(
            """function (param) {
                    return ('第三季度：'+Math.floor(param.value * 10000) / 100) + '%';
                }"""
        ),
        position="inside",
    ),)
    .set_global_opts(title_opts=opts.TitleOpts(title="多个 Liquid 显示"))
)
 
l4 = Liquid().add(
    "lq",
    [0.4954],
    center=["88%", "60%"],
    color=['#C0C0C0'],
    label_opts=opts.LabelOpts(
        font_size=20,
        formatter=JsCode(
            """function (param) {
                    return ('第四季度：'+Math.floor(param.value * 10000) / 100) + '%';
                }"""
        ),
        position="inside",
    ),
)
grid = Grid().add(l1, grid_opts=opts.GridOpts()).add(l2, grid_opts=opts.GridOpts()).add(l3, grid_opts=opts.GridOpts()).add(l4, grid_opts=opts.GridOpts())
grid.render_notebook()
