Overview

The NChartSankeySeries class provides methods to display sankey series. This type of series is a bit different from the others, because it supports series' hierarchy. Sankey diagram consists of nodes and weighted edges. Nodes are represented by series, edges are represented as links to other series (so-called subseries) and weights are represented by points. For example, to build a graph like A-10->B, where A and B are nodes linked with the edge with the weight 10, you have to create two series, A and B, then add B as subseries to A, and create a point for A with value 10.
