| + | Multiple levels are supported, so you can just specify them in the y and x Dimensions. \\ | ||
| + | Grouping the rows and/or columns is done automatically when two or more levels are set in \\ | ||
| + | xDimension and/or yDimension. | ||
| + | |||
| + | Now that you broke down the dataset on the y and x Dimension, it’s time to aggregate \\ | ||
| + | the cell values. Several kinds of aggregations are available including: \\ | ||
| + | sum, min, max, count etc. Future release will provide your own aggregation function. | ||
| + | |||
| + | <code javascript> | ||
| + | |||
| + | aggregates : [{ | ||
| + | member : 'Price', | ||
| + | aggregator : 'sum', | ||
| + | width:50, | ||
| + | label:'Sum' | ||
| + | },{ | ||
| + | member : 'Quantity', | ||
| + | aggregator : 'count', | ||
| + | width:50, | ||
| + | label: 'Count' | ||
| + | }] | ||
| + | </code> | ||
| + | |||
| + | As you have probably noticed in the above example, you could aggregate multiple data \\ | ||
| + | fields, say "Price" and "Quantity". You can easily achieve this by configuring all \\ | ||
| + | required aggregations. | ||
| + | |||

| + | |||
| + | Showing the grand totals for rows and/or columns is pretty easy to configure \\ | ||
| + | ("rowTotals: true" or "colTotals: true"). The group totals are also available \\ | ||
| + | via rowTotals or colTotals configs. | ||
| + | |||
| + | |||
| + | The pivot grid uses JSON data as data source. In the future we will extend it so \\ | ||
| + | that we can read any data source. \\ | ||
| + | |||

| + | |||
| + | Since jqPivotGrid is a open source product, it will constantly be improved with new features. \\ | ||
| + | Feel free to make this happen. | ||
