Information density and subset ratio

Anonymous — Fri, 20 Mar 2015 08:34:31 GMT

Where does qlikview stores the values of Information Density and Subset ratio? I tried using the MemoryStatistics.mem file but couldn't find it there.

I'm not sure if they are stored or they are always calculated. If yes they will be within the qvw-meta-data. You could try it with the export from menu --> export --> document layout and read this xml-file into qv again.

If it is being calculated, it should be stored somewhere. I checked out the -prj files but tough luck..

It mustn't be necessary stored anywhere if it's always calculated on-the-fly and you could make these calculations yourself within the qvw with chart-tables with systemfields like $Table or $Field and calculations over $Row and fieldvaluecount and so on. Have a look in the comments and tools here what is mentioned above:

I believe it calculates on fly only!
