pandas: plot multiple columns of a timeseries with labels.

I am new in python and panda.I am trying to draw graph using python panda. So far i am able to read sqlite database.

import sqlite3
import pandas as pd


conn = sqlite3.connect('demo.db')
df = pd.read_sql("SELECT * FROM ABC", conn)
df.head()

I get this output as result.

Here time stamp is for only single year. I want to plot line graph (Year vs Value) for all Type.

Thanks for help
