x,y = [],[]
csv_reader = csv.reader(open('noneventEventdetect.csv'))
for line in csv_reader:

    T = dt.datetime.strptime(line[0],'%Y-%m-%d %H:%M:%S')
    #print(T)
    y.append(T)
fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(y,x) 
fig.autofmt_xdate()



plt.show()

Answer 1

Time in your title is in a different format than the one in the file you provided, and both of them do not match the format.

For the time in the file you need '%d/%m/%Y %H:%M' , for the time in your title you need '%Y/%m/%d %H:%M:%S'
