Answer 1

you data seem to be strings, you need to parse them to be numbers.

You can use this: Convert argument to number

function getbarseries(month) {
    $.ajax({
      url: siteurl+"patients_report/bardataclinic/"+month,
      type: "POST",
      dataType: "JSON",
        success: function(data) {
           for(var i in data) {
               chart.series[i].addPoint(Number(data[i]['total_check']));
           }
        }
    });
}
