Display Strings in a Time Series

[tonificado]

I need to display in a Time Series a free-string value. The problem is that Time Series in Grafana do not display string values, only numeric values. I want when you hover your mouse over the graph, display in the tooltip the string. It doesn’t work for me to value mapping because the string is a free-string field in my database. I’m using Grafana v9.5.2 in WEB version. Any ideas how to achieve this?
