I am trying to create net hire and termination using new highchart visual . Visual type is waterfall. I have month_end_date as group by field and net movement( custom calculation which is hire - termination) in value section. Following is the code I am using to create waterfall chart. Net movement by month_end_date.
My workaround is to use the extract function month and year (or what you need) and concat the strings. When you concat them in yyyy-mm format, the sorting is automatically correct.
