Try like this

Load *, If(Len(Trim(STYLE)), 0, 1) as StyleNull from datasource;

In front end,

Add dimension as ID, DES, Number and Region

= Only({<StyleNull = {1}>}Style)

Create a Chart.

Use ID, DES, STYLE and NUMBER as dimmentions.

Use RES as expression like that:

Only({<ID=E({<STYLE={"*"}>})>}RES)

IF(LEN(STYLE)=0,' ')

You can simply trick it....

Qlik Sense has the option to "Include null values", but doesn't have the option to "Hide values"!!

So simply just change the entries with values into 'Null', and change the null ones into any value, then hide them by unticking 'Include null values'.

By this, you are literary reversing this option, so you will hide nulls (which previously had values), and will show only the ones with the value (which were original nulls)

=if(Len(STYLE)>0,Null(),'Missing')
