Multiple Nested Chart Panels in TabPanel

[wsharp@advresearch.com]

I am attempting to have multiple chart panels and select each one using a tab. It seems that each time I initialize more than one Ext.Chart.Panel it will break all of the charts. For instance my "cardsNotPulled" chart will work fine until I define the "stockCardsNotPulled" chart. Am I doing something wrong?

    Ext.setup({
        tabletStartupScreen: 'tablet_startup.jpg',
        phoneStartupScreen: 'phone_startup.jpg',
        tabletIcon: 'icon-ipad.png',
        phoneIcon: 'icon-iphone.png',
        glossOnIcon: false,
        onReady: function() {
            window.generateData = function(n, floor) {
                var data = [],
                    p = (Math.random() * 11) + 1,
                    i;
    
                floor = (!floor && floor !== 0) ? 20 : floor;
    
                for (i = 0; i < (n || 31); i++) {
                    data.push({
                        name: i ,
                        data1: Math.floor(Math.max((Math.random() * 20), floor)),
                        data2: Math.floor(Math.max((Math.random() * 100), floor)),

What happens if each chart has it's own store? Something is being shared that shouldn't be.
