Highcharts Sankey customization - highcharts

Question

I can create the following chart:
Highcharts.chart('container', {
title: {
text: 'Highcharts Sankey Diagram'
},
chart: {
styledMode: false
},
plotOptions: {
series: {
// general options for all series
},
sankey: {
curveFactor: 0,
lineWidth: 1
}
},
series: [{
//minLinkWidth: 1,
keys: ['from', 'to', 'weight'],
data: [

['Morocco', 'Japan', 0.01]
],
type: 'sankey',
nodeWidth: 100,
name: 'Sankey demo series'
}]
});
Example
What I need is to have all bands of a small width: about 1.5 mm and not relevant to actual value. What happens now, is that soon as I set all values to the same value the chart refreshes bands with the new width.
Thanks

I am afraid that setting fixed link width is not possible in the current sankey implementation: https://www.highcharts.com/forum/viewtopic.php?f=9&t=47595&p=171541&hilit=sankey+link+sankey+link+width#p171541
