I found solution to make a loop in ApexChart which I want to share with you. First, you should name your chart with id

chart {...
id: 'chart1',
...},

Second, you should make a global var just like ptr = []

Third step is to push there date.

var wynik4 =  
(function  () {
for(i=0; i<str.length - 1; i++){
r =    r + str[i];
ptr.push(r.toFix(1));
}})();

Finally, you should update your chart with new dates using special formula.

function c() {
  ApexCharts.exec('chart1', "updateOptions", {
    xaxis: {
    
      categories: ptr,
    }
  });

  ApexCharts.exec('chart1', "updateSeries", [
    {
    name: 'xyz',  data: ptr,
    }
  ]);
}

That's all, so simple.
