That change would need to be made in the java source code for the server
applet. I think JAR files are compressed files, you should be able to open
them with something like 7-zip (winzip or winrar should be able to do it
too), and extract the source code within.
If you want to do it in javascript, you can accomplish the same task with a
bit of a workaround, by using a DataView with calculated columns. For
example, if you had a DataTable with two columns, both of type string, and
you want the first column to stay a string and you want the second to be
evaluated as an integer, then you could do this:
​var view = new google.visualization.DataView(data);
view.setColumns([0, {
type: 'number',
label: data.getColumnLabel(1),
calc: function (dt, row) {
return parseInt(dt.getValue(row, 1));
}
}]);
chart.draw(view, options);
