        val[0] = val[0] + 1
        return val[0]
    d = collections.defaultdict(idx)
    # give each date an index
    [d[t] for t in sorted(x.index.get_level_values('baropen_datetime').unique())]
    # use the index
    x['idx'] = [d[t] for t in x.index.get_level_values('baropen_datetime')]
    # plot using index
    x.groupby('code').apply(lambda y: plt.plot(y.idx.values,
                                               y.close.values,
                                               label=y.index.get_level_values('code')[0]))
    plt.legend()
    plt.show()
    plt.close()
