How to show a presentation in chart conditionally?

[#1]

Hi,

pretty new to qlikview. I'm trying to find a way to hide columns in straight tables. I want to hide a column if no selections are made in certain field (listbox). If one or more selections are made in that certain field, the column would be shown in the chart.

I propably need to put a condition for that expression in presentation?

Thank you!

Hi,

   What i understood from the question is you want to show the straight chart only if a selection is made on any listbox.

   If yes then you can do in this way.

   Go to properties of Straight Table.

   In general tab you will see calculation condition.

   Paste expression like this.

   if(GetSelectedCount(Filed_Name)>1,1,0)

Not quite: I want to only hide a column in chart if no selections are made in certain specific field, not any field. So if user hasn't selected anything in field x, a certain column would be hidden in the chart. All the other columns would still be shown on the chart.

Thank you!

HI,

   Go to properties of straight table, in presentation tab. You will see the columns there.

   Click on the column you want to hide. then click on conditional and paste the same above expression there.
