[chart][conditional][date selectors] Attaching a calendar controller to a chart
Hi,
I am rather new to Qlikview and I need to control the values shown in a chart by a calendar, so the calendar shows only data newer to the date selected in the calendar. Till now, I haven't got any success. My steps have been:
1.- I created a new variable to hold the date selected: sel_date
2.- I created a calendar with the variable (sel_date).
3.- I create a graph, with a single dimension ( product ) and an expression: count(invoices),
4.- The actual selection fails, I doesn't show any data whenever I try to make the expression conditional, such as:
count({invoices} if (date_of_purchase >sel_date, 1 )
where date_of_purchase is a column of DDBB, an imported qlikview data.
