How to use 'null' in expressions

[#1]

Hello,

I want to hide a chart when a field has no selection, but I have no idea what the 'null'-selection in qlikview is. The one I mention below is not working. Can someone help?

=(GetCurrentSelections(CS_ChartSelection)) NOT NULL)

Thxs

try

=GetSelectedCount( CS_ChartSelection )

i want to do the same thing as you here, where about do you put that expression?

Thanks

Hey,

I looked around on this forum before I saw the reply of swuehl and I used this solution:

(len(CS_ChartSelection)=0)

worked as a charm

Hi,

     you can try using this also.

     IsNull(GetFieldSelections(CS_ChartSelection))

     IsNull is the equivalent qlikview method to use 'null' values in expression.
