Panels , Worldmap Panel

Hello there , is someone here who can answer me a few questions about the world map panel?
For example:
Can i change the Colour on the map for different location with different colours, if yes how?
And, if i try to name the circle i can name the first part but afterwards " Name : NaN" how can i get rid of the “NaN”?
I use MSSQL if that is important
