Hi @Barabossa! Sorry your question didn't get any attention earlier, hopefully I can help some.
Stacked bar charts are certainly possible inside of Kibana. Here's a prior question that shows an example config: Stacked and grouped columns in bar chart
But I don't believe you'll be able to group it by state like you're looking to. I'd recommend creating a Scripted Field to first group the states like you're looking to do then split on that field, instead of the raw state field.
