Problems with Trading View

My best regards, my friend, I am developing an exchange of cryptocurrencies which I have to generate a candlestick chart. I am occupying the library charting library of tradingview, the doubt that I have is how to insert data into the graph. I leave the script of my graphic I would greatly appreciate your help.

Greetings.

  function getParameterByName(name) {
      name = name.replace(/[\[]/, "\[").replace(/[\]]/, "\]");
      var regex = new RegExp("[\?&]" + name + "=([^&#]*)"),
              results = regex.exec(location.search);
      return results === null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
  }

  TradingView.onready(function()
  {
    var widget = new TradingView.widget({
      height: '100%', 
      width: '100%',
      symbol: 'AAPL',
      interval: 'D',

      library_path: "charting_library/",
      locale: getParameterByName('lang') || "es",
