If I have understood correctly, you want a chart with all the days, even though you dont have data for all these days.
I would create a master calendar with all the days of the months you are using. I would use the day as Dimension in the chart, checking "Show all values".
PD: I didnt realize you are using QlikSense. I´m not sure how the charts work there, but you can give it a try anyway.
Make a calendar table with all dates you need.
Put the movements in a mapping table
Read into a new table from the calendar table and add the movements to the dates. Then use Peek / Previous calculate the next days balande based upon the current day's comsumption and the previous day's endiing stock. This will give you a stock balance for the empty days as well.
