Forcing 0 Values into Line Chart

mattdt1811 — Wed, 25 Nov 2020 16:16:04 GMT

Hi All,

I am struggling to get a line chart of mine to show zero values.

I have tried un-ticking Suppress When Value is Null & Supress Zero Values but it still does not work.

I have a master calendar to generate missing dates in my script and need to insert these values with a 0.

The expression in the chart I have tried to do this with is below but this does not work;

=if ( count({$<FreightPaid={'Paid in UK'},INSURED={'INSURED'}>}JOBCOUNTER) > 0 , (Count({$<FreightPaid={'Paid in UK'},INSURED={'INSURED'}>}JOBCOUNTER)), 0 )

I have also been advised I can add one dummy zero record into the fact table for each month by using a calendar and concat it back to the original table but I do not know how to do this.

I have attached an example QVW.

For reference on selection of 2017 there was 1 job in Sep - I want the line chart to show 0 value for all the remaining months on one continuous line to get a better idea of the trend.

Thanks in advance.

Hi Thirumala,

Yes this does work a lot better thanks. However it is showing as below when I insert this into my master QVW – I think this is where the User ID has raised no jobs for the month.

I have also been advised this can be solved by using the below script beneath the Temp Calendar Script;

Concatenate(TEMP1)
load 'Paid in UK' as FreightPaid,
'Insured' as INSURED,
TempDate as [CREATION DATE],
'BALDWIN@M' as [USER CREATED BY],
1 as Dummy,
0 as JOBCOUNTER
Resident TempCalendar;

Drop Table TempCalendar;

And then using:

=sum({$<FreightPaid={'Paid in UK'},INSURED={'INSURED'}>}JOBCOUNTER)

As the expression in the chart.

This does work for my own user ID however I will need to get this to work for all User ID’s, Customers, Locations etc.

Do you know how I would do this?

Many Thanks.

Not 100% sure but can you give a try with the below expression:

=sum({$<FreightPaid={'Paid in UK'},INSURED={'INSURED'}>}JOBCOUNTER) * AVG(1)

Unfortunately this generates the same result, however it is still a lot better than what I was using previously.

Thanks for your help.
