[python工具] 如何使用plotly制作散列图

注意

• 最好使用python3， 我在mac上，默认2.7，安装起来相当费劲，使用python3 + pip3 + virtualenv 比较合适

安装

pip install plotly

测试

➜  plotly_test git:(master) ✗ pwd
/Users/muahao/work/vpc/muahao_tools/plotly_test
➜  plotly_test git:(master) ✗ cat first.py
from plotly.graph_objs import *
import plotly.offline
trace0 = Scatter(
    x=[1,2,3,4,],
    y=[10,15,13,17]
)
trace1 = Scatter(
    x= [1,2,3,4],
    y= [16,5,11,9]
)
plotly.offline.plot([trace0,trace1])
