pyecharts主要基于Web浏览器进行显示,绘制的图形比较多,包括折线图、柱状图、饼图、漏斗图 地图和极坐标图等。使用pyecharts绘图代码量很少,但绘制的图形比较美观。
pyecharts 分为 v0.5.X 和 v1 两个大版本,v0.5.X 和 v1 间不兼容,v1 是一个全新的版本 v0.5.X支持 Python2.7,3.4+。
经开发团队决定,0.5.x 版本将不再进行维护,0.5.x 版本代码位于 05x 分支 ,v1仅支持 Python3.6+,新版本系列将从 v1.0.0 开始。
本文所讲主要基于 pyecharts 1.7.1 版本进行展示 安装命令为:
pip install pyecharts==1.7.1
二、pyecharts柱状图/条形图全解
from pyecharts import options as opts
from pyecharts.charts import Bar
l1=['星期一','星期二','星期三','星期四','星期五','星期七','星期日']
l2=[100,200,300,400,500,400,300]
bar = (
Bar()
.add_xaxis(l1)
.add_yaxis("基本柱状图", l2)
.set_global_opts(title_opts=opts.TitleOpts(title="Bar-基本示例", subtitle="我是副标题"))
)
bar.render_notebook()
参数介绍:
add_xaxis:添加横坐标,需传入列表 add_yaxis:添加纵坐标,需传入列表,切列表元素为数值
from pyecharts import options as opts
from pyecharts.charts import Bar
l1=['星期一','星期二','星期三','星期四','星期五','星期七','星期日']
l2=[100,200,300,400,500,400,300]
bar = (
Bar()
.add_xaxis(l1)
.add_yaxis("基本柱状图", l2)
.set_global_opts(
title_opts=opts.TitleOpts(title="Bar-基本示例"),
yaxis_opts=opts.AxisOpts(name="人流量"),
xaxis_opts=opts.AxisOpts(name="星期"),)
)
bar.render_notebook()
from pyecharts import options as opts
from pyecharts.charts import Bar
l1=['星期一','星期二','星期三','星期四','星期五','星期七','星期日']
l2=[100,200,300,400,500,400,300]
l3=[300,400,500,400,300,200,100]
bar = (
Bar()
.add_xaxis(l1)
.add_yaxis("l2", l2)
.add_yaxis("l3", l3)
.set_global_opts(title_opts=opts.TitleOpts(title="Bar-基本示例", subtitle="我是副标题"),
toolbox_opts=opts.BrushOpts(),)
)
bar.render_notebook()
opts.BrushOpts()为圈选工具,如图形右上角所示
from pyecharts import options as opts
from pyecharts.charts import Bar
l1=['星期一','星期二','星期三','星期四','星期五','星期七','星期日']
l2=[100,200,300,400,500,400,300]
bar = (
Bar()
.add_xaxis(l1)
.add_yaxis("l2",l2,category_gap=0, color='#FFFF00')
.set_global_opts(title_opts=opts.TitleOpts(title="Bar-基本示例", subtitle="我是副标题"))
)
bar.render_notebook()
category_gap:设置间隔
color:设置柱状图颜色
from pyecharts import options as opts
from pyecharts.charts import Bar
l1=['星期一','星期二','星期三','星期四','星期五','星期七','星期日']
l2=[100,200,300,400,500,400,300]
l3=[300,400,500,400,300,200,100]
bar = (
Bar()
.add_xaxis(l1)
.add_yaxis("l2", l2)
.add_yaxis("l3", l3)
.reversal_axis()
.set_series_opts(label_opts=opts.LabelOpts(position="right"))
.set_global_opts(title_opts=opts.TitleOpts(title="横向柱状图"))
)
bar.render_notebook()
reversal_axis将图形反转
position="right"表示将数值在图形右侧显示,同理left、center分别表示左侧和中间
