Modify length of Highcharts sankey-diagram connection line

Question

I have got a question of Highcharts sankey-diagram. Is there anyone can help me with changing the length of connection line?

It's too wide between data columns. I want to narrow the size to half.

here is the sample code from hightchart demo: https://www.highcharts.com/demo/sankey-diagram

Answer 1

You can use marginLeft & marginRight properties to narrow the size of the series:

  chart: {
    marginLeft: 200,
    marginRight: 200
  },
