 ===== Options settings ===== ===== Options settings =====
 +Looking into the boss task we can see that the categories and products are fields which will be used in our grid. This data is "​static"​ and we should tell jqPivotGrid this. This is achieved with xDimension option:
 +
 +<code javascript>​
 +...
 +xDimension : [
 +   {
 +       ​dataName:​ '​CategoryName',​
 +       label : '​Category',​
 +       width : 90
 +   }, {
 +       ​dataName:​ '​ProductName',​
 +       ​label:​ '​Product',​
 +       ​width:​ 90
 +   }
 +]
 +</​code>​
 +
 +
 +With this setting we tell jqPivotGrid that the data will be grouped first by Category and then by Product. \\
 +These fields should be taken from the JSON response which names are CategoryName and ProductName (see the JSON  response above). \\
 +
 +Next we should tell jqPivotGrid which field is the country field. With this setting we will generate dynamic columns (yDimension).\\
 +Seen into the source data this is the Country field. Now the settings should be:
 +
 +<code javascript>​
 +...
 +yDimension : [
 +   {
 +      dataName: '​Country'​
 +   }
 +]
 +</​code>​
 +
 +Now the missed part is which fields we should actually summarize? This is achieved with the aggregates option using the fields Price and Quantity.
 +
 +<code javascript>​
 +aggregates : [
 + {
 +           ​member : '​Price', ​
 +           ​aggregator : '​sum', ​
 +           ​width:​50,​
 +           ​label:'​Sum'​
 +        }, {
 +           ​member : '​Quantity', ​
 +           ​aggregator : '​sum', ​
 +           ​width:​50,​
 +           ​label:'​Qty'​
 +        }
 +]
 +</​code>​
 +
 +The missed settings are how we can make sumaries on columns and rows. This of cource is achieved with two line of code - \\
 +rowTotal : true and \\
 +colTotal: true
 +
 +The final code with jqGrid setting is:
 +
 +<code javascript>​
 +<script type="​text/​javascript">​
 +jQuery(document).ready(function(){
 +
 + jQuery("#​grid"​).jqGrid('​jqPivot', ​
 + "​data1.json",​
 + // pivot options
 + {
 + xDimension : [
 +                   ​{dataName:​ '​CategoryName',​ label : '​Category',​ width: 90}, 
 +                   ​{dataName:​ '​ProductName',​ label : '​Product',​ width:90}
 +                ],
 + yDimension : [
 +                   ​{dataName:​ '​Country'​}
 +                ],
 + aggregates : [
 + {member : '​Price',​ aggregator : '​sum',​ width:50, label:'​Sum'​},​
 + {member : '​Quantity',​ aggregator : '​sum',​ width:50, label:'​Qty'​}
 + ],
 + rowTotals:​ true
 + colTotals : true
 +
 + }, 
 + // grid options
 + {
 + width: 700,
 + rowNum : 10,
 + pager: "#​pager",​
 + caption: "​Amounts and quantity by category and product"​
 + });
 +});
 +</​script>​
 +  </​head>​
 +  <​body>​
 +...
 +     <​table id='​grid'></​table>​
 +     <​div id='​pager'></​div>​
 +...
 +   </​body>​
 +</​html>​
 +</​code>​
 +
 +The final result can look like this
