Update stock price in anychart without re-plotting whole chart – Jquery ajax

I am playing with the Anychart stock candlestick chart which is very nice, in order to update the chart I use a setInterval function but it re-plots the entire chart which sucks because if I am zooming or something it resets and starts over obviously. Is there a way I can just update last price from the database every couple seconds without re-plotting the whole chart?

Current setInterval function to load chart:

setInterval(function() {
  $.get('chart_data.php', function(data) {
     $(".main_cont").replaceWith(data);
  });
}, 2000);

My chart_data variable:

$chart_data .= "{'x':'".$open_time."','open': ".$open.",'high': ".$high.",'low': ".$low.",'close': ".$close."},";

chart_data.php file:

anychart.onDocumentReady(function() {

  // create a data table
  var table = anychart.data.table('x');
  // add data
  table.addData([<?php echo $chart_data;?>]);
    
  // add data
  //table.addData([ {'x':'08/09/2020 10:11','open': 11000,'high': 10000,'low': 8000,'close': 8500}]);

  // create a stock chart
  var chart = anychart.stock(true);

  // create a mapping
  var mapping = table.mapAs({
    'date': 'date',
      'open': 'open',
      'high': 'high',
      'low': 'low',
      'close': 'close',
      'fill': 'fill'
  });
      
  var plot = chart.plot(0);
  // add a series using the mapping
  chart.plot(0).candlestick(mapping).name();

  // set container id for the chart
  chart.container('container');
  var series = chart.plot(0).candlestick(mapping);

  chart.scroller().xAxis(false);

  // initiate chart drawing
  chart.draw();
});

I would like to replace the setInterval function with something that just replaces the last price data from the database to move the candle up or down, if a new record is added then draw the new candle. I have the script to update the candle or add a new candle I just cannot find a way to do it without re-drawing the whole chart.
