Best way of automatically adding row ID

Hi there,

Spotfire has an in-built RowId() function I would use for this. So create a calculated column in the data table of interest (File->Data->Add Calculated Column, or File->Data->Column Properties then Insert->Calculated Column from drop down on top right, or if you are using Spotfire 7 - the Insert menu then insert calculated column), and type in the command:


This creates a unique ID for every row, and each time new data is read it automatically generates new ids for the new rows.

Hope this helps.
