pyecharts操作三

• pyecharts 是一个用于生成Echarts图表的Python库。Echarts是百度开源的一个数据可视化JS库，可以生成一些非常酷炫的图表。

• 环境安装

  • pip install pyecharts

• 检查版本

import pyecharts
print(pyecharts.version)
2.0.3

• GL关系图

import random

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

nodes = []
for i in range(50):
for j in range(50):
nodes.append(
opts.GraphGLNode(
x=random.random() * 958,
y=random.random() * 777,
value=1,
)
)

links = []
for i in range(50):
for j in range(50):
if i < 50 - 1:
links.append(
opts.GraphGLLink(
source=i + j * 50,
target=i + 1 + j * 50,
value=1,
)
)
if j < 50 - 1:
links.append(
opts.GraphGLLink(
source=i + j * 50,
target=i + (j + 1) * 50,
value=1,
)
)

gl = (
GraphGL(init_opts=opts.InitOpts())
.add(
series_name=“”,
nodes=nodes,
links=links,
itemstyle_opts=opts.ItemStyleOpts(color=“rgba(255,231,114,0.8)”),
linestyle_opts=opts.LineStyleOpts(color=“rgba(255,231,114,0.8)”, width=3),
force_atlas2_opts=opts.GraphGLForceAtlas2Opts(
steps=5,
edge_weight_influence=4,
),
)
.set_dark_mode()
)
gl.render_notebook()

• 图形组件

from pyecharts.charts import Bar
from pyecharts.commons.utils import JsCode
from pyecharts.faker import Faker

gr = (
Bar()
.add_xaxis(Faker.choose())
.add_yaxis(“商家A”, Faker.values())
.add_yaxis(“商家B”, Faker.values())
