Hello there, I have the same problem as yours. However, I read the official documentation of value mapping and it says that value mapping accepts variables, which is pretty confusing. Have you figured out this problem? Is it us that use variables incorrectly or it is actually a function that had not yet been added to Grafana? We also have the same issue where we wish to convert a query values to a more friendly display names base on a variable or a dynamic value mapping based on a query. Im facing the same problem.
