Inputting coordinates to maps

[JogNTMK]

Hi all

I'm new to google maps api so bear with me.

I need to input coordinates to google maps and have the path displayed.

The database or file that contains the coordinates will be updated often.

From what I understand I need to input my coordinates into the MVCarray and it will update the map automatically but I dont know how to do this.

I've looked through the api and i've seen the push() function but how do i use it and how do i get the coordinates from the file to the function.

Thanks in advance for any help
