Hi,  
in this example:

how i can get the “sum” values of each bar, in javascript ?  
of course, if i print y data values of graph, like this way:

var gd = document.getElementById(“plotlyDIVID”);  
console.log(gd.data.y);

console.log returns me y value, not y “calculated” value.

thanks for support
