JavaScript/jQuery Sankey - Rearrange Nodes

The Sankey's algorithm distributes nodes between columns. This distribution ensures a proper node-to-node flow direction. You cannot move nodes from one column to another because this alters the flow direction.

However, you can sort nodes within a column. Configure the sortData object so that its fields correspond to nodes. The field values should be node weights: the heavier the node, the lower it is in its column. Refer to the sortData description for an example.

Nodes in a column are separated by a space. You can use the node.padding property to specify this space. In the following code, this distance is reduced to 1 pixel:

JavaScript
  • $(function() {
  • $("#sankeyContainer").dxSankey({
  • // ...
  • node: {
  • padding: 1
  • }
  • });
  • });

Each column can be aligned vertically. You can find an example in the alignment property's description.
