matplotlib基础

数据如下：

DATEVALUE 1987/1/13.4 1987/2/13.2 1987/3/13.1 1987/4/13.6 1987/5/13.2 1987/6/13.1 

# -*- coding: UTF-8 -*-import matplotlib.pyplot as pltimport pandasdt=pandas.read_excel("matplotlibTest.xlsx",delimiter="\t")dt['DATE']=pandas.to_datetime(dt['DATE'])print(dt.head(3))plt.plot(dt['DATE'],dt['VALUE'])plt.xlabel("Month")plt.ylabel("Number")plt.title("aaaa")plt.xticks(rotation=45)plt.show()

输出：
D:\python\python.exe D:/warkspace/pythonTest/com/Matplotlib1.py        DATE  VALUE0 1987-01-01    3.41 1987-02-01    3.22 1987-03-01    3.1
