Hi,
Below is the html that generated scatter plot.
Date is already embedded as :
['Age', 'Weight'],
[ 8, 12],
[ 4, 5.5],
[ 11, 14],
[ 4, 5],
[ 3, 3.5],
[ 6.5, 7]
]);
How to modify the code to let it load local data sources.
for example my html saved to :
C:\Users\my pc\personal document
under same folder includes my data file:
C:\Users\my pc\personal document\data.txt
(or in cvs, json, xml format)
is there a method of modifying the api code to let it reference the local
file. thanks.
<html>
<head>
<script type="text/javascript" src="https://www.google.com/jsapi";></script>
<script type="text/javascript">
google.load("visualization", "1", {packages:["corechart"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Age', 'Weight'],
[ 8, 12],
[ 4, 5.5],
[ 11, 14],
[ 4, 5],
[ 3, 3.5],
[ 6.5, 7]
]);
var options = {
title: 'Age vs. Weight comparison',
hAxis: {title: 'Age', minValue: 0, maxValue: 15},
vAxis: {title: 'Weight', minValue: 0, maxValue: 15},
legend: 'none'
};
var chart = new
google.visualization.ScatterChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
</script>
</head>
<body>
<div id="chart_div" style="width: 900px; height: 500px;"></div>
</body>
</html>
