Hello guys, I have a time series panel in Grafana, and it’s stacked 100%, and I would like to know if it’s possible to display the values on the tooltip as percentage to.

So right now, my panel looks like

And this is my query (repeat for each category)

SELECT STR_TO_DATE(CONCAT(year, '-01-01'), '%Y-%m-%d') AS time, ROUND(quantity / 1000000, 2) as 'Europe (excl.EU-27)'
FROM net4co2.ghg_world_emission_per_region
WHERE data_type = 'CU' AND category = 'E'
ORDER BY time;

The desired one
