Using Jquery or Javascript you can update label after it load .
STEPS :
1. creating setTimeout function that run after 2 seconds.
2. Loop through all the label and calculate total (to percentage generate)
3. Loop Through Again and replace label value with your value.
window.setTimeout(function(){
var getTotal = 0;
var selector = "#revenue-block tspan"
document.querySelectorAll(selector).forEach(function(ele){
if(ele && ele.innerHTML && ele.innerHTML.split(',').length > 1){
var arr = ele.innerHTML.split(','); // paid, 2000k or pend,3000k
var value = +arr[1].replace(/[a-zA-z, ]/g,''); // 2000k => 2000
if(value > 0){
getTotal += value;
}
}
});
document.querySelectorAll(selector).forEach(function(ele){
if(ele && ele.innerHTML && ele.innerHTML.split(',').length > 1){
var arr = ele.innerHTML.split(','); // paid, 2000k or pend,3000k
var value = +arr[1].replace(/[a-zA-z ]/g,''); // 2000k => 2000
var per = Math.round(((value/getTotal)*100) * 100) / 100; // 34.556788 => 34.55 (you can also used number.toFixed(2) )
if(per > 0){
ele.innerHTML = ele.innerHTML + ' (' + per + '%)';
}
}
});
},2000);
