Remove missing date space and tricklabel from graph matplotlib candlestick

In my program i have generate a candlestick in axis and a data plot in axix2. For candlestick graph i have created a variable named data. it is python dictionary type variable. where i have assign date .'date': ['2018/10/30', '2018/11/03', '2018/11/04', '2018/11/05', '2018/11/07', '2018/11/10', '2018/11/11']. other key is 'open','high','low','close' and 'volume'
Here date '2018/10/30' and '2018/11/03' there is a gap of date.
Here also date '2018/11/07' and '2018/11/10' there is a gap of date.
So when i generate my candlestick graph missing date space is taken.How can i remove this missing date space. my program:
