Goodmorning everyone,

I'm trying to implement the "candlestick" graph from the Chartjs library;

I took the example shown in the documentation as a guide and everything works correctly: the 'x' and 'y' axes show the correct values; The problem is that the actual graph is not displayed, even if the Cartesian axes are present

this is the code used for implement Chart and the result image

var barCount = 5;
var initialDateStr = '01 Apr 2017 00:00 Z';

var barData = getRandomData(initialDateStr, barCount);
//console.log(barData)
//function lineData() { return barData.map(d => { return { x: d.x, y: d.c} }) };

var chart = new Chart(ctx, {
    type: 'candlestick',
    data: {
        datasets: [{
            label: 'CHRT - Chart.js Corporation',
            data: barData
        }]
    }
});

var getRandomInt = function(max) {
    return Math.floor(Math.random() * Math.floor(max));
};

function randomNumber(min, max) {
    return Math.random() * (max - min) + min;
}

function randomBar(date, lastClose) {
    
    var open = +randomNumber(lastClose * 0.95, lastClose * 1.05).toFixed(2);
    var close = +randomNumber(open * 0.95, open * 1.05).toFixed(2);
    var high = +randomNumber(Math.max(open, close), Math.max(open, close) * 1.1).toFixed(2);
    var low = +randomNumber(Math.min(open, close) * 0.9, Math.min(open, close)).toFixed(2);
    return {
        x: date.valueOf(),
        o: open,
        h: high,
        l: low,
        c: close
    };

}
