Dear asgallant, here is the source elements.
here the data table columns containing cuYear and pastyr with money
values.
Objective is to custom format the tooltip text and show Y Axis Lables
with cuYear values with the $ sign.
Hope it helps to understand the objective.
google.load('visualization', '1', { packages: ['corechart'] });
var data = new google.visualization.DataTable();
data.addColumn('string', 'x');
data.addColumn('number', cuYear);
data.addColumn('number', pastyr);
var formatter = new google.visualization.NumberFormat(
{ prefix: '$'}
);
formatter.format(data, 1);
formatter.format(data, 2);
new
google.visualization.LineChart(document.getElementById('visualization')).
draw(data,
{
curveType: "none",
