Renderer function in the series of ExtJS
===

I am using ExtJS series renderer function to set the fill property of scatter chart, instead of using MarkerConfig property. Since I want to fill different color for each points. Its working fine.


    renderer : function(sprite, record, attr, index, store) {
       Ext.apply(attr, {
           fill : '#F00'
       }
    }


But I want to set the type property, so that each point will show in different types like circle, cross, plus, diamond and so on. It is not working. And radius of the scatter point, I am unable to set the property in renderer function.

Please help me, how to do that in renderer function.

Thanks,
Boopathy
