How to add "Others" in a pie chart with ranking in Webi

How to Bring “Others” in a Pie chart when ranking is applied in the data.

Let’s say there is a set of Region and there Revenue like below:

My requirement is  to get the TOP 3 Region based on Revenue and to display its percentage share from overall revenue. From below table we want to create a pie chart using Region and Percentage column.

Pie chart always display total out of 100, in the above block, the percentage total is 68.09% only.

This will not come in a pie chart properly.

Option will be to show Other’s contribution and show in the pie chart.

For eg.

This table can now be properly displayed in Pie chart.

Now comes the interesting part, how to bring value “Others” in the data.

I followed below steps:

Step: 1 Added an object in universe with Select statement as ‘Others’ and pointed it to Region from List of tables. Like below:

Step: 2 In the Webi Report which already has Region and revenue data, created another query selecting the newly created object (Region-Others) and revenue.

Step 3: Merge the object Region and Region-Others.

Step 4: Created four variables:

a.       Revenue_variable=If([Region]="Others";[Query 1 (1)].[Revenue];[Query 1].[Revenue])

This variable is used to give data for others in the block along with other regions.

b.      Variable1 = [Query 1 (1)].[Revenue]-(Sum([Query 1].[Revenue]) In Block)

This is used to subtract the value of all regions-sum of regions in block, which will assign others data.

c.       Variable2=If([Region]="Others";[Variable1];[Revenue-Variable])

This issued to display the values for all regions including “Others”.

d.      Final Percentage=([Variable2]/Sum([Variable2]) In Block )

This is used for calculating percentage.

Step 5: Applied ranking based Revenue_variable. Although I need Top 3 , I selected Top 4(4^th for the Others)

Step 6: Using region and Percentage turned it to Pie chart.

So the pie chart is correct now.

Note: If you have query filters in Query 1, apply same filter in query 2 also.
