Help understanding and editing this function

Hello, I would like to edit this template and need to know how to edit the contents of the graphs, the data is linked to a function called "dashboard_cur" I tried looking in the VBA code but I can't find it, I need to edit or create a function that works the same as this.

where did you find what is in the image? I search everywhere in the file and the VBA project and found nothing.

Thank you very much, I realized this after a few hours, I have never used such utility so I had no clue how this was done, nonetheless thank you very much!
