DevExtreme Angular - 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 option to specify this space. In the following code, this distance is reduced to 1 pixel:

jQuery
JavaScript
$(function() {
    $("#sankeyContainer").dxSankey({
        // ...
        node: {
            padding: 1
        }
    });
});
Angular
HTML
TypeScript
<dx-sankey ... >
    <dxo-node [padding]="1"></dxo-node>
</dx-sankey>
import { DxSankeyModule } from "devextreme-angular";
// ...
export class AppComponent {
    // ...
}
@NgModule({
    imports: [
        // ...
        DxSankeyModule
    ],
    // ...
})
Vue
App.vue
<template> 
    <DxSankey ... >
        <DxNode :padding="1" />
    </DxSankey>
</template>

<script>
import DxSankey, { DxNode } from 'devextreme-vue/sankey';

export default {
    components: {
        DxSankey,
        DxNode
    }
}
</script>
React
App.js
import React from 'react';
import Sankey, { Node } from 'devextreme-react/sankey';

class App extends React.Component {
    render() {
        return (
            <Sankey ... >
                <Node padding={1} />
            </Sankey>
        )
    }
}

export default App;

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