Setting up the basic setting which will be done for all solution is mentioned here
Sample Table Structure

Id SampleName Branch State Location

Now I want to create a cyclic drill containing

1 Branch
2 State
3 Location

Loading info and creating in order load

load * inline
SampleName, SampleName_Label
Branch, Branch Name
State, State Name
Location, Location Name

Once data is loaded there are 2 ways to view drill_below inFilter (available in sense app)
It is good but wouldn’t able to get the default value and multiple selections may be enabled. Although this works in a way where client won’t care if first load drill is visible and selected.
Much more are available use which ever fits your criteria
Now We have drill selection ready now to link chart to the Drill.
Thus we have selected drill to connect chart to drill
Have two following ways:

  • Use if condition
  •  Use Pick Match
    As the above two are obvious, if the info is large, creates lag in chart reloads,
    Thus the following approach,
    Uses the following function capabilities, in Size, Create dimension
    looking like

Hence create the measure as per requirements; gives the cyclic group.

6. How to connect Qlik Sense with R?

This is the most simple way to use R with Qlik: Enlarging R is the idea behind this, and transfer to a respective folder that Qlik sense is gonna read and thus loads the data.

After this, to always run, you need to refresh your analysis, after creating a .exe file.

Thus code needs to be:"add path to R \R\add R VERSION(num.num)\bin\R.exe"
--labour --rahul
"add path to Intellipaatscript\Intellipaatscript.R"
"add path over hereIntellipaatreport\Intellipaatreport.txt"
