I'm not familiar with either Ruby or Gon. However, your
data.addRows([
[ gon.months, gon.money]
]);
line looks weird. Is gon.months an array? Same question for gon.money. The
addRows function accept an array of arrays, where each inner array contains
data values. In your case, since you have two columns of type number, the
data values are all numbers, so the inner array should be an array of
length 2 where the elements are numbers. Not an array of length 2 where the
elements are arrays. See the
addRows<https://developers.google.com/chart/interactive/docs/reference#DataTable_addRows>documentation.
