Map diagram in Excel.

Hello everyone, 

I'm currently writing my master thesis about the real estate market in Odense, Denmark, and i would like to display the differences in housing prices from different parts of the city. I've no problem showing for the different cities in Denmark ex Copenhagen, Aarhus and Odense together or Odense alone. But if want to show for Odense North, South, East, Vest and Centrum it says my data is wrong. Does anyone know how to fix it, and if it's not possible to it, does anyone know how to do it manually, or maybe whom to contact so it could be made? 

Thanks. 

Best Regards

Kris
