Count(Interval) not working

Tue, 18 Nov 2014 13:49:07 GMT

Hi,

Data

2014-11-17 09:00:00,2014-11-17 08:00:00

2014-11-17 09:00:00,2014-11-17 07:00:00

2014-11-17 09:00:00,2014-11-16 08:00:00

2014-11-17 09:00:00,2014-11-15 07:00:00

Load Script

LOAD

@1,

@2,

Interval(@1-@2 ,'DD') as "closing_interval_days"

FROM [lib://Documents/temp_qlik_data.txt]

(txt, codepage is 1252, no labels, delimiter is ',', msq);

If I add a 'table' to the sheet, it correctly gives me the following values for the intervals

But if I add a pie chart with a count of the intervals I get

0 count 1

1 count 1

2 count 1

I would have hoped for

0 count2

1 count1

2 count1

Is this correct? Have I misunderstood interval? Are the underlying minutes/seconds still there in the background?

Any help appreciated.

John.

You are close. The issue is this

Interval(@1-@2 ,'DD') as "closing_interval_days"

The interval will store all the details (days, hours, minutes, seconds etc..) between the 2 timestamps but the interval() function with 'DD' is just a formatting measure. So the pie chart believes they are different even if that is not obvious. When you format the day dimension to show more details as below, its apparent

To resolve this replace it with this which will round it to whole integer days and it should work the way you want.

floor( Interval(@1-@2 ,'DD')) as "closing_interval_days"

Fantastic, thanks for getting me the right answer so quickly.

Appreciated.
