Change Grouping Summary type

[mikep]

If I'm grouping by a certain field, I want a field's summary to be sum, otherwise I want it to be avg (summary: { type: "avg" }).
How would I accomplish this?

You can use groupChange event to detect grouping by certain field and set field summary accordingly.

Code: [Select]

groupChange: function(){
alert( this.option('groupModel.dataIndx') );
},
