Google Map API rows limit

I am adding near 100 rows to a Google Map using the Map Visualization API.

It renders correctly but keeps showing me the tag "some of the data rows were truncated" and only 400 rows (locations) are added to the map.

How can i add more element开发者_如何学Pythons to my map?

I just changed to google map api, insted og google viz api and everything worked grate.
