Drill_below:

load * inline

[

SampleName, SampleName_Label

Branch, Branch Name

State, State Name

Location, Location Name

];

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 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

$(=if(GetSelectedCount(SampleName_Label)=0,’Location’,only(SampleName)))

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