The Legend of a Visiblox Chart is often never used to its full potential. This post will introduce a few simple ideas on how to enable user interactions with LegendItems in order to interact with the associated series.

Previous blog posts have introduced FilterStrategies and some different ways that they can be used. Today we introduce the DynamicFilterStrategy, which allows you to use different FilterStrategies depending on the chart's zoom level.

Sound complicated? It isn't.
