ApexCharts Treemap chart - force columns to be just one and only one series name

I am using the ApexCharts js library in WordPress and Gravity Form Surveys (glikerts) and use them as my data source but my issue is their subtotals called anchors need to be in a hierarchical chart where each column is just one and only one series name. In this chart I have 4 series names and i want just 4 columns. Is there a setting in Options that I can leverage? Any ideas? My solution is for psychologists and the surveys are taken every 30 days. Thanks very much!
