In addition to the method previously provided, you can use a platform to do this (actually several platforms do this). Choose Analyze->Quality and Process->Manage Spec Limits. Choose your process variables and click OK. If your spec limits are entered as column properties, they will populate automatically. Otherwise you can use Load from Limits Table or you can type them in yourself. From the red triangle next to Manage Spec Limits, choose Color Out of Spec Values. The out of spec values are now colored in your data table.
