simple-segment-aggregation.js

Aggregate consecutive segments by their events.

This library is best used with data returned from time-segments.js and simple-segment-aggregation.js

Motivation

Some visualizations aggregate consecutive segments into a single unit. This library groups any segment with the same content into the same block.

Caveats

This library requires that each of your events have a unique identifier.

Concepts

Aggregates

An aggregate is an Object with the following properties

• events - the events contained within the aggregation
• start - a Unix timestamp representing the start of the aggregation
• duration - the length of the aggregation
• continuesForward - a Boolean representing whether any of the events in this aggregate are in the subsequent aggregate
• continuesBackward - a Boolean representing whether any of the events in this aggregate are in the previous aggregate

API

This library exposes a single method.

aggregate( group, scale [, options] )

It accepts a group of segments and returns a group of aggregates. scale can be any resolution that moment.js supports. The number of aggregates you get could be the same number of segments that you pass in, or less, but never more.

Options can be used to customize the behavior of the API. The available options are:

• idAttribute - The key containing the Event's unique identifier
