我们可以试用可视化包——Pyechart。
Echarts是百度开源的一个数据可视化JS库，主要用于数据可视化。
pyecharts是一个用于生成Echarts图标的类库。实际就是Echarts与Python的对接。
安装
pyecharts兼容Python2和Python3。执行代码：
pip install pyecharts(快捷键Windows+R——输入cmd)
初级图表
1.柱状图/条形图
[python] view plain copy from pyecharts import Bar [python] view plain copy attr=["衬衫","羊毛衫","雪纺衫","裤子","高跟鞋","袜子"] v1=[5,20,36,10,75,90] v2=[10,25,8,60,20,80] bar=Bar("各商家产品销售情况") bar.add("商家A",attr,v1,is_stack=True) bar.add("商家B",attr,v2,is_stack=True) bar#bar.render()
2.饼图
[python] view plain copy from pyecharts import Pie attr=["衬衫","羊毛衫","雪纺衫","裤子","高跟鞋","鞋子"] v1=[11,12,13,10,10,10] pie=Pie("各产品销售情况") pie.add("",attr,v1,is_label_show=True) pie #pie.render()
3.圆环图
