用highcharts做甘特图展示

一、首先，需要引插件：

jquery-1.11.3.js

highcharts.js

highcharts-more.js

二、body中的html代码

<div id="container_center">div>

三、js代码

<script type="text/javascript">
    var xArray;
    var yArray;
    var seriesArray;
    $(function() {

        $.ajax({
               type: "POST",    
               dataType: "JSON",    
               url: "<%=basePath%>admin/project/getprojectdatas.php?id=${id}",
               success : function(result){
                   xArray = result.xArray;
                   yArray = result.yArray;
                   seriesArray = result.seriesArray;
                   $('#container_center').highcharts({
                        chart: {
                            type: 'columnrange',
                            inverted: true //反转

                        title: {

                            text: ''
                        },
                        xAxis: {
                            categories: xArray

难点

数据格式需要多思考
