There are many different ways to get data from a database into a DataTable
for the charts to use. The simplest method is to output the values
directly into javascript in jsp. The syntax for this might change
depending on the java framework you are using, but here's a basic example
of how you might go about it:
function drawChart () {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Category');
data.addColumn('number', 'Value');
data.addRows([
// replace ${a} and ${b} with the requisite tags for outputting
variables in your chosen framework
['A', ${a}],
['B', ${b}]
]);
var chart = new
google.visualization.PieChart(document.querySelector('#myPieChart');
chart.draw(data, {
height: 400,
width: 600
});
}
You can also set up an AJAX data source to query for your data instead of
directly outputting the data. There is a java library for creating a data
source if you are interested in giving that a try (documentation
here<https://developers.google.com/chart/interactive/docs/dev/dsl_intro>
).
