I need only 3 field to be visible in the Pie chart and the rest of the fields should fall under 'Others' irrespective of the values. only NDA, Contract and price list should be  displayed in the Pie chart and rest of the field in 'Others'. (refer below image )

Please help to achieve this.

If you want to display the top 3 (and Others), you can use Dimension Limit.

If you want it to be hard-coded to those values (and others) you need to create either a field (in script) or a calculated dimension along the lines of (If(Match([Contract Type],'Value1', 'Value2', 'Value3'),[Contract Type],'Other')
