Aggregation

ZingGrid has default behaviors for calculating the average, count, min, max, and sum values for a given column. These aggregation values are displayed in a single row at the base of the grid.

Average

Display the average of a column's values in the footer, like so:

<zg-column index="exampleIndexName" foot-cell="avg"></zg-column>
