Customize Hierarchy Footer | Data Views | MESCIUS DataViewsJS Demos

This example demonstrates how to customize hierarchy footers. In this demo, various aggregates have been added to each nodes' footer. To customize these footers, use the template option in the footer option array found in the hierarchy options. In this example, the template option contains formatting and the formulas necessary to display aggregates.
