Hello, 

I have 100 details one diameter (e.g.66+0.04). After measuring I need divide this details on 3 group: 1) 66.005..66.01;2) 66.01..66.016,3) 66.016..66.02).I made table of measuring value in PiWeb Designer and add condition for field measuring value, but I  received only color group. I want make filter, and create 3 tables with different tolerance.

  Groups can be  3,4 or more.
