QlikView App Dev

[#1]

I have a column newdate. I want to create a mastercalendar and store the frequency of dates (if a date occurs 3 times in new date column its frequency should be 3, if there is no entry for a particular day its frequency should be zero). The purpose of doing this is i want to make bar chart and line chart of number of tweets per day, per month etc. So i want to store data in mastercalendar. The bar should show zero for a particular day if there was no date entry in new date column on that day and 3 if the date is three times in new date column.

Order By TempDate ASC; 

Drop Table TempCalendar; 

is this master calendar right? i have dates from 7/10/2015 till 2/8/2016  in my database but it creates master calendar only from 12/29/2014 till 2/26/2015

[maxgro · Accepted solution]

add a trace after drop table Temp to check the min e max date

let v1=date($(varMinDate));

let v2=date($(varMaxDate));

trace varMinDate = $(v1);

trace varMaxDate = $(v2);

[MarcoWedel]

please post some values of your field "onlydate" in table "newtab".
