when I display stock price series on minutes basis, you know, in a day there are many minutes without trading, so we see discontinous price on the chart. I think this could be done like this (in python):

    ts = pd.Series(index=datetime_list, value=stock_price_list)
    params = {
        'title':title,
        'xaxis':dict(title=xaxis, x=range(len(ts)), mark=datetime_list)
        'yaxis':dict(title=yaxis),
    }
    layout = go.Layout(**params)

this is a straigforward way and easy to implement, please consider it. thanks a lot!!!
