I use stacked bar chart.
I want to know How to add lines between stacked columns/bars.
You can draw lines between stacked columns by using multiple FastLineRenderableSeries.
A new line series can be added for each stacked horizontal group.
Alternatively , you can use the LineAnnotation. For more information, please take a look at the following documentation:
Please note that the (start, end) point of the line segment between columns will be in the center of the column.
There is no built-in way to get the coordinate of the left/right edge of a column.
