Group grid store data by multiple dimensions to better analyse it.
You can let users summarise the entire grid store and/or groups.
The grouping panel plugin allows users to drag-n-drop grid columns in the grouping panel to change the store grouping. That's a must have feature for a grid.
If you prefer to calculate the summaries on the server side then you can do so. The plugin will fetch the results from the server and display them.
The summaries plugin allows users to choose what type of summary function they need on a grid column.
