Since OriginPro 2015, once you specify a column to the Observation Labels in the Input Data branch, the column values will be automatically shown as label in the Score Plot and Biplot in report sheet.
Alternatively, or in the previous version of OriginPro, you can also put the column for label as the first column of the worksheet and set it as text, then the column will be automatically put next to the plot data in the result sheet. You can use data reader to examine the plot in greater detail as in the tutorial
Set it as labels of the score plot/biplot in steps below
