Used the following command:
/give PlayerName filled_map 1 6 {Decorations:id:"+",rot:180,type:8,x:127,y:127}}
UPD:
Was able to create map with line:
/give PLayerName filled_map 1 6 {Decorations:[{id:"+",rot:180,type:8,x:127,z:127}]}
"House" icon is shown. Map is updated correctly. However, the problem with absence of Player's position arrow still persists.
Also, "scale" tag seems to be ignored.
Was able to create with static marker with command:
/give PLayerName filled_map 1 6 {Decorations:[{id:"+",rot:180,type:8,x:127,y:127}]}
Still, player's postition is not shown on map
