Hi Anderson,
I looked at your code and saw that you are declaring the chart as a
local variable in one method:
function drawChart() { ...
*var* chart = new
google.visualization.AreaChart(document.getElementById('div_chart'));
and trying to use the same variable on the handler method:
function selectHandler() { ...
var selection = chart.getSelection();
So the handler execution crashes at this point.
Perhaps you would like to declare the handler method inside the
drawChart method
