Deficiency in the Renko dataset

[haydar-can]

var taWeb = require("ta.js")
var data = [[8, 6], [9, 7], [9, 8]]; // [high, low]
var bricksize = 0.5;
await console.log(taWeb.ren(data, bricksize));
// 0: [8, 8.5, 8, 8.5], 1: [8, 8, 7.5, 7.5], 2: [8, 8.5, 8, 8.5]

When this function works, I cannot obtain information on what date and how much volume the bricks in the Renko chart were formed. What should I do about this issue?

So you need the volume to be included into the function?
