Hi I am trying to convert a list of dates as strings to an x axis in matplotlib and I can\'t seem to get it to come out right.

dates =  [\'2014-05-06\', \'20

    Is this the goal? (Threw in rotation because it almost always comes up, with dates.)

    datelist =  ['2014-05-06', '2014-05-07', '2014-05-08', '2014-05-09', '2014-05-10',    '2014-05-11', '2014-05-12', '2014-05-13']
    
    import matplotlib
    from matplotlib import pyplot
    from matplotlib import dates
    import datetime
    
    converted_dates = list(map(datetime.datetime.strptime, datelist, len(datelist)*['%Y-%m-%d']))
    x_axis = converted_dates
    formatter = dates.DateFormatter('%Y-%m-%d')
    
    
    y_axis = range(0,8)
    pyplot.plot( x_axis, y_axis, '-' )
    ax = pyplot.gcf().axes[0] 
    ax.xaxis.set_major_formatter(formatter)
    pyplot.gcf().autofmt_xdate(rotation=25)
    pyplot.show()
