Cumulative Second Measurement in Column Line Multiaxis Chart

[edgar.aguilar]

Take the example described at

https://community.jaspersoft.com/documentation/tibco-jaspersoft-studio-user-guide/v62/dual-axis-multi-axis-and-combination-charts

My question here is, I want the second measurement (Line) to be cumulative (Sum). The described example says Total 1997, 1998, 1999, but how can be done that line to be a grand total adding the quantities. In Other words: 1st measurement detailed as Freight per country and per year, but Second Measurement being summarized.

Thank you in advance
