Accepted answer

First of all try loading data trough load() and unload() methods, that's the correct way of doing it (can be a json, url, rows or columns) like this example:

  columns: [
    ['data1, 100, 200, 150, ...],
  unload: ['data2', 'data3']

Please note that this method is highly documented and should be read:

To force redraw, you can call flush() method:
