Checkweigher

This chart illustrates a typical composite plot, resulting from the overlay of a computed curve on experimental results. In this experiment, 13 test packs were carefully made up at a range of weights spanning the likely error band of the automatic weighing belt. The range was symmetric about the intended set weight of 226g.

When showing a fitted mathematical function, it is often very helpful to use the 'Curves' style to have the points joined by a smooth curve, rather than a set of straight lines.
