    Please use the [ CODE ] tags when you post... this thing is nearly impossible to read.

    this might help to make the graph stackable

    Ext.define('Ext.chart.series.StackedColumn', {

    extend: 'Ext.chart.series.Column',


    type: 'stackedColumn',
    /**
    * @private
    */
    column: true,


    constructor: function(config) {
    this.callParent(arguments);

    var me = this;
    me.stacked = true;
    me.initialStacked = me.stacked;
    },


    });
