使用pyecharts1.7进行简单的可视化大全
(编辑：jimmy 日期: 2024/10/22 浏览：3 次 )
近期，又有接触到pyecharts这个包的使用，后面发现这个曾经好用的包发生了一些变化，为了方便大家的使用，这里整理如下：
绘图风格theme:默认WHITE
LIGHT, DARK, WHITE, CHALK, ESSOS, INFOGRAPHIC, MACARONS, PURPLE_PASSION, ROMA, ROMANTIC, SHINE, VINTAGE, WALDEN, WESTEROS, WONDERLAND
1.柱状图绘制
1.1 最基础的柱状图
from pyecharts.charts import Bar,Grid
from pyecharts import options as opts
from pyecharts.globals import ThemeType
import random
import numpy as np
# 准备数据
name=["A","B","C","D"]
salery=[random.randint(3000,5000) for i in range(4)]
#绘图
bar=Bar(init_opts = opts.InitOpts(width='600px',height='400px'))
bar.add_xaxis(name)
bar.add_yaxis("salery",salery)
bar.set_global_opts(title_opts=opts.TitleOpts(title="收入情况"))
#仅在notebook中显示
bar.render_notebook()
#在HTML中显示
bar.render("收入情况")
效果图：
1.2 稍微复杂的柱状图
为了减少代码量，此处不再导入包。绘制收入和消费情况，并使用新风格,并添加副标题，使用新版本的链式写法。
#准备数据
name=["A","B","C","D"]
salery=[random.randint(3000,5000) for i in range(4)]
cost=[random.randint(1000,2000) for i in range(4)]
#绘图
bar=(
Bar(init_opts = opts.InitOpts(width='600px',height='400px',theme=ThemeType.LIGHT))
.add_xaxis(name)
.add_yaxis("salery",salery)
.add_yaxis("cost",cost)
.set_global_opts(title_opts=opts.TitleOpts(title="收入及消费情况",subtitle="随机样本"))
)
bar.render_notebook()
#效果图：
1.3 堆叠式柱状图
使用堆叠式柱状图（部分堆叠），并自定义颜色，修改图例的显示位置，不显示数字，改变背景颜色
#准备数据
name=["A","B","C","D"]
salery=[random.randint(3000,5000) for i in range(4)]
cost=[random.randint(1000,2000) for i in range(4)]
#所在城市平均薪水
salery_ave=[random.randint(3000,4000) for i in range(4)]
colors=["#007892","#ff427f","#fc8210","#ffd8a6"]
#进行绘图
bar=(
Bar(init_opts = opts.InitOpts(width='600px',height='400px',bg_color=colors[-1]))
.add_xaxis(name)
.add_yaxis("salery",salery,stack="stack_one")
.add_yaxis("cost",cost,stack="stack_one")
.add_yaxis("salery_ave",salery_ave)
.set_colors(colors)
.set_series_opts(label_opts=opts.LabelOpts(is_show=False))
.set_global_opts(title_opts=opts.TitleOpts(title="收入、消费及其城市平均收入情况"),
legend_opts=opts.LegendOpts(type_="scroll", pos_right="right", orient="vertical")
)
)
bar.render_notebook()
效果展示：
1.3.1 调整标题与图的位置
grid=Grid() # 分别调整上下左右的位置，参数为像素值或百分比 grid.add(bar,grid_opts=opts.GridOpts(pos_top="30%",pos_bottom="10%",pos_left="10%",pos_right="10%")) grid.render_notebook()
效果演示
1.4 绘制簇状图
#准备数据
name=["A","B","C","D"]
salery=[random.randint(3000,5000) for i in range(4)]
cost=[random.randint(1000,2000) for i in range(4)]
#所在城市平均薪水
salery_ave=[random.randint(3000,4000) for i in range(4)]
colors=["#007892","#ff427f","#fc8210","#ffd8a6"]
#进行绘图
bar=(
Bar(init_opts = opts.InitOpts(width='600px',height='400px',bg_color=colors[-1]))
.add_xaxis(name)
.add_yaxis("salery",salery)
.add_yaxis("salery_ave",salery_ave)
.reversal_axis()
.set_colors(colors)
.set_series_opts(label_opts=opts.LabelOpts(position="right"))
.set_global_opts(title_opts=opts.TitleOpts(title="收入、消费及其城市平均收入情况"),
legend_opts=opts.LegendOpts(type_="scroll", pos_right="right", orient="vertical")
)
)
bar.render_notebook()
效果图演示
1.5 数据量大时的显示方法
#准备数据
name=[chr(i) for i in range(65,85,1)]
salery=[random.randint(3000,5000) for i in range(20)]
#所在城市平均薪水
salery_ave=[random.randint(3000,4000) for i in range(20)]
colors=["#007892","#ff427f","#fc8210","#ffd8a6"]
#绘图 修改 orient为vertical，可将滑动按钮移动垂直方向
bar=(
Bar(init_opts = opts.InitOpts(width='600px',height='400px',bg_color=colors[-1]))
.add_xaxis(name)
.add_yaxis("salery",salery)
.add_yaxis("salery_ave",salery_ave)
.set_colors(colors)
.set_series_opts(label_opts=opts.LabelOpts(is_show=False))
.set_global_opts(title_opts=opts.TitleOpts(title="收入、消费及其城市平均收入情况"),
legend_opts=opts.LegendOpts(type_="scroll", pos_right="right", orient="vertical"),
datazoom_opts=[opts.DataZoomOpts(type_="slider")]
)
)
bar.render_notebook()

2.绘制散点图
2.1 普通散点图
import random
from pyecharts import options as opts
from pyecharts.charts import Scatter
from pyecharts.globals import ThemeType
#准备数据
name=["A","B","C","D"]
salery=[random.randint(3000,5000) for i in range(4)]
cost=[random.randint(1000,2000) for i in range(4)]
#所在城市平均薪水
salery_ave=[random.randint(3000,4000) for i in range(4)]
colors=["#007892","#ff427f","#fc8210","#ffd8a6"]
#进行绘图
scatter=(Scatter(init_opts = opts.InitOpts(width='600px',height='400px',theme=ThemeType.DARK))
.add_xaxis(name)
.add_yaxis("salery",salery)
.add_yaxis("cost",cost)
.set_global_opts(title_opts=opts.TitleOpts(title="收入与消费情况")))
scatter.render_notebook()
查看效果：
2.2 3D散点图绘制
import random
from pyecharts import options as opts
from pyecharts.charts import Scatter3D
from pyecharts.faker import Faker
#准备数据
data = [(random.randint(0,100),random.randint(0,100),random.randint(0,100)) for i in range(50)]
name=["长","宽","高"]
#绘图
scatter3D=Scatter3D(init_opts = opts.InitOpts(width='600px',height='400px')) #初始化
scatter3D.add(name,data,
grid3d_opts=opts.Grid3DOpts(
width=100, depth=100
))
scatter3D.set_global_opts(title_opts=opts.TitleOpts(title="散点图"),
visualmap_opts=opts.VisualMapOpts(
range_color=Faker.visual_color #颜色映射
))
scatter3D.render_notebook()
效果图：
2.3 带涟漪的散点图
symbol的类型：
“pin”,“rect”,“roundRect”,“diamond”,“arrow”,“triangle”
import random
from pyecharts import options as opts
from pyecharts.charts import EffectScatter
from pyecharts.globals import ThemeType
#准备数据
name=["A","B","C","D"]
salery=[random.randint(3000,5000) for i in range(4)]
cost=[random.randint(1000,2000) for i in range(4)]
#所在城市平均薪水
salery_ave=[random.randint(3000,4000) for i in range(4)]
colors=["#007892","#ff427f","#fc8210","#ffd8a6"]
#进行绘图
scatter=(EffectScatter(init_opts = opts.InitOpts(width='600px',height='400px',theme=ThemeType.DARK))
.add_xaxis(name)
.add_yaxis("salery",salery,symbol="pin",symbol_size=20,symbol_rotate=180)
.add_yaxis("cost",cost,symbol="rect",symbol_size=20)
.set_global_opts(title_opts=opts.TitleOpts(title="收入与消费情况"),
xaxis_opts=opts.AxisOpts(splitline_opts=opts.SplitLineOpts(is_show=True)), #添加网格
yaxis_opts=opts.AxisOpts(splitline_opts=opts.SplitLineOpts(is_show=True))
)
.set_series_opts(effect_opts=opts.EffectOpts(scale=3,period=2)) #调整涟漪的范围和周期
)
scatter.render_notebook()
效果图如下：
