Generally, we have seen that when we write Max(date) in chart then it results in number format ex: 156725, but in my case it is directly resulting in date format.
Also when I uses expressions which contains such variables then in general it uses num for comparison of dates
Ex: {<[Invoice Date]={">=$(=num(vStartDate))<=$()=num(vEndDate)"}>}
but here it is not showing data and if we removes 'num', then the data gets appeared,
where vEndDate=date(max([Invoice Date]),'DD-MM-YY').
Please help me to solve this issue.
