Create a visualization with 2 dimensions and 2 metrics

I am trying to create a visualization with 2 dimensions and 2 metrics, the data has the following fields:

Country, Age_Group
value_past, value_present

I want to create a single visualization in question which shows me the past vs present value broken by country and age group. I tried building a bar chart with country and age_group as dimensions, but then I am able to use only 1 metric, I am only able to use both metrics when I choose only 1 dimension. How can I achieve both metrics by both dimensions?

I think you want to combine two questions on a dashboard, so one question will be past, the other question the present.
