问题
I need to create a chart that shows a series of events (see image, in this case 6) that have a duration of time between them.
I've been able to approximate this with a sankey chart and curveFactor:0, but I can't seem to adjust the space between each node.
Is there some way I can achieve this? It doesn't have to be sankey chart. I can use anything in the Highcharts library. I'd also considered a stacked bar chart but ran into another set of issues.
