我在我的网站上使用谷歌图表，在服务器端使用 parse.com。我有一个标签<div id="chart_div"> </div>它绘制图表。对于图表，这是Javascript部分：

$( document ).ready(function() {
    var currentUser = Parse.User.current();
    console.log( currentUser );
var stepcount = Parse.Object.extend("stepCount");
var query = new Parse.Query(stepcount);
query.equalTo("user", currentUser);
query.find({
  success: function(results) {  
    for (var i = 0; i < results.length; i++) {
      var object = results[i];    
      alert(object.id + ' - ' + object.get('numberOfSteps'));
    }
  },
  error: function(error) {
    alert("Error: " + error.code + " " + error.message);
  }  });  });
function drawMultSeries() {
      var data = new google.visualization.DataTable();
      data.addColumn('string', 'Day');
      data.addColumn('number', 'Motivation Level');
      data.addColumn('number', 'Energy Level');
      data.addRows([
        ['Monday', 1, .25],
        ['Monday', 1, .25],
        ['Monday', 1, .25],
        ['Monday', 1, .25],
        ['Monday', 1, .25],
        ['Monday', 1, .25],
        ['Monday', 1, .25],
      ]);
      var options = {
        title: 'Motivation and Energy Level Throughout the Day',
        hAxis: {
          title: 'Time of Day',
          format: 'h:mm a',
          viewWindow: {
            min: [7, 30, 0],
            max: [17, 30, 0]
          }
        },
        vAxis: {
          title: 'Steps'
        }
      };
      var chart = new google.visualization.ColumnChart(
        document.getElementById('chart_div'));
      chart.draw(data, options);
    }

我正在尝试检索当前用户的步数，但我不知道如何将其插入图表中。

你可以这样做。

   $( document ).ready(function() {
        var currentUser = Parse.User.current();// igebs romeli user aris shemosuli da abrunebs objectId
        console.log( currentUser ); 
    var stepcount = Parse.Object.extend("stepCount"); //database shi class saxeli 
    var query = new Parse.Query(stepcount); 
    query.equalTo("user", currentUser);
    query.find({
      success: function(results) {  

        for (var i = 0; i < results.length; i++) {
          var object = results[i];    
          alert(object.id + ' - ' + object.get('numberOfSteps'));
         //console.log(object.get('numberOfSteps'));
         arrayOfSteps.push(object.get('numberOfSteps'));
         console.log(arrayOfSteps[i] ) ;
        }
      },
      error: function(error) {
        alert("Error: " + error.code + " " + error.message);
      }  });  });
    function drawMultSeries() {
      x = [];
      for(var j=0; j<arrayOfSteps.length;j++){
          x.push(
            ['date', 1, arrayOfSteps[j]]
          );};
          var data = new google.visualization.DataTable();
          data.addColumn('string', 'Day');
          data.addColumn('number', 'Motivation Level');
          data.addColumn('number', 'Energy Level');
          data.addRows([x[0],x[1],x[2],]);
