Is there any example code about drawing a line connecting points of known coordinates?
Anybody can help me about that?


Thank you very much in advance

  Hi everybody,
  I've got a sequence of GPS lat/lon positions on a MySql db table. I need to draw a line which connects them. Is there any example code about doing that?

  For drawing polygons with MapGuide, reading data from a MySql table, I saw that I need to create a POLYGON attribute on the DB with vertices points coordinates.Do I need to create similarly a LINE attribute on the DB? If yes, how can I dynamically execute MySql queryes for doing that, so that MapGuide can draw a line starting from a sequence of GPS coordinates?


  I hope you can help me, thank you in advance
  Carmelo
