It is just a simple script project that is supposed to create a pie chart from the data in a spreadsheet. I had it working when I built the DataTable within the HTML file, but I tried to adjust it with a query in order to pull the data from a spreadsheet and make the dashboard dynamic with changes to the spreadsheet.
Whenever I deploy it however, it just shows up as a blank screen. Any help/thoughts is appreciated! I will get it eventually...
HTML File Code:
<html>
<head>
<!--Load the AJAX API-->
<script src="https://www.gstatic.com/charts/loader.js"></script>
<script>
google.charts.load('current', {packages: ['corechart']});
google.charts.setOnLoadCallback(drawChart);
function initialize() {
var opts = {sendMethod: 'auto'};
// Replace the data source URL on next line with your data source URL.
var query = new google.visualization.Query('https://docs.google.com/spreadsheets/d/1BiNoiV10xrAU8PwdJfgldneLwFuCnY5GhQRDEIzftd8/edit#gid=0', opts);
}
// Send the query with a callback function.
function handleQueryResponse(response) {
if (response.isError()) {
alert('Error in query: ' + response.getMessage() + ' ' + response.getDetailedMessage());
return;
}
var data = response.getDataTable();
// Set chart options
var options = {'title':'How Much Pizza I Ate Last Night',
'width':400,
'height':300};
// Instantiate and draw our chart, passing in some options.
var chart = new google.visualization.PieChart(document.getElementById('chart_div'));
google.visualization.events.addListener(chart, 'select', selectHandler);
chart.draw(data, options);
}
//enter alert on user screen when clicking on section of chart
function selectHandler() {
var selectedItem = chart.getSelection()[0];
var value = data.getValue(selectedItem.row, 0);
alert('The user selected ' + value);
}
</script>
</head>
<body>
<!--Div that will hold the pie chart-->
<div id="chart_div" style="width:400; height:300"></div>
