How to show merged regions / continents in TeeChart map series?

I am using TeeChart (4.1.2015.8062) for Winforms to display the world map in our application. This map can be displayed for predefined regions / continents. Teechart refers to this as the types of world maps. for example, the available map types are Africa, Asia, Australia, Central America, Europe, Europe15, Europe27, Middle East, North America, South America, Spain, USA, USAAvaiAlaska, World.

We want to show a map combined for Asia and Australia. TeeChart currently displays separate maps of Asia and Australia, but it has no provision for combining and displaying the two continents.

Is there any way to combine and display areas such as: asia and australia, asia and the middle east?

Thank,

Charade
