This icon is a plotting specification for average (zonal or meridional) cross-section for Hovmøller diagram plots from a suitable GRIB data source. It can also take the output from an Average a Hovmoeller Data icon as an input. In this case, a consistency check is performed between the parameters that are common to both icons.

In addition to the parameters required for the average cross section the  Hovmøller diagram computation, this icon specifies the axis details as well as the plot positioning in the plot frame of the display window / paper sheet and the overlay of different data units in the same plot.
