未捕获的TypeError：无法读取未定义的jqplot.highlighter.min.js的属性'eventListenerHooks'：4

Question

你好我的PHP代码和javascript有问题！问题是 “未捕获的TypeError：无法读取未定义的jqplot.highlighter.min.js的属性'eventListenerHooks'：4”

我不知道为什么我会接受这个错误。有问题的javascript中的行是：

d.jqplot.eventListenerHooks.push(["jqplotMouseMove", f]);" 

并写

  

无法读取未定义

的属性'eventListenerHooks'

我的jqplot的代码是：

$(document).ready(function() {
        var tips = [<?php 
        if (!empty($scheduledTips)) {
            foreach ($scheduledTips as $value) {
                echo "['" . $value->date . "'," . $value->tips . '],';
            }
        } else {
            echo '["No_tips",0]';
            } 
        ?>];
       var quizzes = [<?php
        if (!empty($scheduledQuizzes)) {
            foreach ($scheduledQuizzes as $value) {
            echo "['" . $value->date . "'," . $value->quizzes . '],';}
        } else {
            echo '["No_Quizzes",0]';
            } 
        ?>];
       var commitments =[ <?php
        if (!empty($scheduledCommitments)) {
            foreach ($scheduledCommitments as $value) {
                echo "['". $value->date . "'," . $value->commitments . '],';
            }
        } else {
            echo '["No_Commitments",0]';
            } 
        ?>];  

        var plot1 = $.jqplot('ScheduledTips', [tips,quizzes,commitments], {
            title: 'Actions',seriesColors: ['#00749F','#7bc523','#e87511','#00ffd2','#6b4423','#c7bebe','#847847', '#153115', '#FF0000', '#F0A804', '#800080','#000000','#fc9758',

            location: 'e',
            rendererOptions:{numberRows: 3, placement: 'outside'}
        },
        cursor: {
            show: true,
            zoom: true,
            looseZoom: true,
            showTooltip: false
        },
            series: [{pointLabels: {

                },rendererOptions: {

                    // Speed up the animation a little bit.

                }}], series: [ {label: "Tips"},{label: "Quizzes"},{label: "Commitments"}],
            grid: {
                drawGridLines: true, // wether to draw lines across the grid or not.
                gridLineColor: '#cccccc', // CSS color spec of the grid lines.

                shadowOffset: 1.5, // offset from the line of the shadow.
                shadowWidth: 3, // width of the stroke for the shadow.
                shadowDepth: 3
            },
      axes:{
      yaxis: { pad: 1.05,min:0} ,
        xaxis:{
          renderer:$.jqplot.DateAxisRenderer, 
                 pad: 1.05,
                  tickOptions: {
                        showGridline: false
                    }
        }
      }, 
            highlighter: {
                show: true,tooltipLocation: 'n',
                tooltipContentEditor : tooltip,
                sizeAdjust: 18.5}
  });
    });

html的代码是：

if (!empty($stats)) {
            echo '<div class="col-md-12"><div id="ScheduledTips" style="height:400px;width:700px;margin-left:00px;padding-bottom:20px"></div></div><br/>';
        }

我已经加载了所有的js库。但是我从页面开始那个问题！任何人都知道如何解决它？
