Bar chart with calculated dimension for (M & YTD)

Wed, 02 Mar 2011 09:01:30 GMT

My objective is to build a 100% stacked bar chart with 2dimension and 1expression. In x Axis, I would find [Current Month], [YTD], [YTD-1] (so, I can compare the repartition over the time).

I guess I need to create a calculated dimension for that; but how will my observations of the current month, being counted twice for [Current Month] and [YTD]?

Hi,

best way is, to create a table as calender in the script with all needed datefunctions and combine it to your datefield in data. Than you dont need to create a dynamic dimension (what of course is possible).

Thanks for the quick reply. I am trying to picture your idea but I am still new in QV.

On another object, I use following expressions:

For observation of the month: count( { $ < OpenMonth = {'$(#v_dateselection)'} >} [SD])

For observation of the YTD: count( {$ <OpenMonth = {"=NUM(OpenMonth) <= $(=NUM(v_dateselection))"}, OpenYear={$(=YEAR(v_dateselection))}> }SD)

where v_dateselection is the a date format

Now, in OpenMonth, I have thousand of different dates, so how am I going to build a 'calender' table? Would I need a column OpenMonth to make a link with my fact table? Should this column contain all distinct value of OpenMonth from my fact table?

I can't figure out the format of your calender table. It is empty? All columns are only build from expression based on the date?

Thanks in advance,

This is the output I am getting with the solution mentioned above.

The output is what I want, but the solution is not. I don't mind to load an additional table, but not in the format mentioned above (because it serves only this need) and dirty the data model.

I finally followed the example mentioned here:

http://community.qlik.com/forums/t/32982.aspx

Here is my adjusted script (I am dealing with Date which are always the 1st day of the month):

Dates:
Load Distinct OpenMonth as Date
Resident Fact;

OpenAsOf:
LOAD
"Date" as "As of OpenMonth"
,'YTD' as "OpenMonth Range"
,MonthName("Date", - iterno() + 1) as "OpenMonth"
RESIDENT Dates
WHILE year("Date") = year(MonthName("Date", - iterno() + 1))
;
CONCATENATE (OpenAsOf)
LOAD
"Date" as "As of OpenMonth"
,'YTD-1' as "OpenMonth Range"
,MonthName("Date", - iterno() -11) as "OpenMonth"
RESIDENT Dates
WHILE year("Date")-1 = year(MonthName("Date", - iterno() -11))
;
CONCATENATE (OpenAsOf)
LOAD
"Date" as "As of OpenMonth"
,'M-1' as "OpenMonth Range"
,MonthName(Date,-1) as "OpenMonth"
RESIDENT Dates
;
CONCATENATE (OpenAsOf)
LOAD
"Date" as "As of OpenMonth"
,'M' as "OpenMonth Range"
,"Date" as "OpenMonth"
RESIDENT Dates
;
DROP TABLE [Dates]
;
