Characteristic values of the particle size distribution and other measured values can be plotted over
as a trend diagram (Q(t) diagram).
This module is the optimum tool if there is interest in time-resolved measurements, for example, drop sizes of sprays over the spray formation period (fractions of a second), or the production quality of a cement plant (hours, days, weeks).

Quality limits for the measured product can also be plotted, in order to provide the optimum information for the control room.

Other relations like the dependency of the particle size on the environmental temperature can also be plotted if, for example, the temperature has been stored as a user defined parameter of the measurement.
