Display Values in Bar Chart

Hey there,
thank you for the great plugin. I’m having an issue with the display of the values in a stacked bar chart.
If I use a google sheet as the source of the chart I can see the value of each bar when I hover over the bar. Which is fine. This doesn’t work though if the source of my chart is a simple CSV-File. Is it possible to make this work or alternatively just show the bar values inside each bar? I tried all chart attributes that made sense to me, but nothing seemed to work.

This is my code:
