and there is demo code :

function getR() {
var report = {};
report['dataSource'] = {"data" : getData()};
return report;
}
function getData() {
return [{
"Color": "green",
"M": "September",
"W": "Wed",
"country": "Canada",
"state": "Ontario",
"city": "Toronto",
"Price": 174,
"Quantity": 22
}, {
"Color": "red",

"W": "Mon",
"Time": "1000",
"country": "USA",
"state": "California",
"city": "Los Angeles",
"Price": 30,
"Quantity": 19
}];
}
var pivot = {};
pivot[0] = new Flexmonster({
container: "pivot-container",
componentFolder: "https://cdn.flexmonster.com/", 
toolbar: true,
report: {
dataSource: {
data: getData()
}
}
});
pivot[1] = new Flexmonster({
container: "pivot-container",
componentFolder: "https://cdn.flexmonster.com/", 
toolbar: true,
report: {
dataSource: {
data: getData()
}
}
});
pivot[2] = new Flexmonster({
container: "pivot-container",
componentFolder: "https://cdn.flexmonster.com/", 
toolbar: true,
report: {
dataSource: {
data: getData()
}
}
});
var nbReport = 3;
function reloadReport(n) {
pivot[n].setReport(getR());
console.log("out : " + n);
pivot[n].on('reportcomplete', function () {
console.log("in : " + n);
n++;
if (n < nbReport) {
reloadReport(n);
}
});
}


reloadReport(0);
