For metrics, you can select the aggregation method.
The aggregation method is the function used to consolidate the metric values into a single value for each group dimension value, or for each combination of group and series dimension values.

If the chart is grouped by country, then to get a single sales amount value for each country, you might add together all of the values for each country, calculate the average of the values for each country, or select the largest value for each country.
