.lp file is a Lua script which is accessible from HTTP. Here's a minimal example that outputs data in JSON format:

Code:

<?
data = { 1, 2, 3 }
print(json.encode(data))

Then, in Custom JavaScript you can load data from .lp like this (in callback function passed to google.charts.setOnLoadCallback). Once data is loaded you can create new chart and draw it.

Code:

$.getJSON('/user/data.lp', function(data) {
  console.log(data);
  // draw chart here
});
