How to show all tags even there are no data in the time range

Currently if I select Last 7 days, I will see all the tags(‘MA900117’, etc) like follow, around 80+ total tags,
but when I select last 2 days the it only show around 60 tags, it make sense because probably for the other 20+ tags we don’t receive values for last 2 days. But How can I fixed to show still 80+tags when I select last 2 days data. I try fill 0 and fill none, looks not working.
Any suggestion will be appreciated.
