Hi @ToastFrench,
It’s hard to help when I can’t replicate your code and run it on my computer. But look at this example here: Column name inside sunburst
You see how customdata[0] refers to “country_txt” and customdata[1] refers to “years”.
See here for another example. This one uses hover_data. How can I manipulate the hovertemplate using Sunbust chart?
Make sure to not use hoverinfo because it is depreciated.
