Yes, you can draw multiple charts. You need to make a few adjustments to
your code in order to make it work. First, you only want to load the
Visualization API once, and use one callback. Second, your two drawChart
functions need to have different names; when you create a new function with
the same name as an existing function, you overwrite the existing
function. Third, you need two unique container divs for your charts to
draw in. Here's one way you might organize it:
function drawChart1 () {
// draw the first chart
}
function drawChart2 () {
// draw the second chart
}
function init () {
drawChart1();
drawChart2();
}
google.load('visualization', '1', {packages:['corechart'], callback: init});
and in your HTML:
<div id="chart_div_1" style="width: 400px; height: 500px;"></div>
<div id="chart_div_2" style="width: 400px; height: 500px;"></div>
