    Hi,
    This is my code for chart

    //CHART START


    window.chartStore = new Ext.data.JsonStore({
    fields: ['name', 'Value'],

    //data:generateData()
    });


    var chartPanel = new Ext.chart.Panel({
    title: 'Policy Portfolio Chart',
    // margin: '-100 0 10 28',


    fullscreen: true,
    items: {
    cls: 'pie1',
    theme: 'Demo',
    store: chartStore,
    shadow: false,
    animate: true,
    insetPadding: 20,
    legend: {
    position: {
    portrait: 'bottom',
    landscape: 'bottom'
    }
    },
    interactions: [{
    type: 'reset',
    confirm: true
    },
    {
    type: 'rotate'
    },
    {
    type: 'iteminfo',
    gesture: 'taphold',
    listeners: {
    show: function(interaction, item, panel) {
    var storeItem = item.storeItem;
    panel.update(['<ul><li><b>Policy: </b>' + storeItem.get('name') + '</li>', '<li><b>Value: </b> ' + storeItem.get('Value') + '</li></ul>'].join(''));
    }
    }
    },
    {
    type: 'piegrouping',
    //snapWhileDragging: true,
    onSelectionChange: function(me, items) {
    if (items.length) {
    var sum = 0,
    i = items.length;
    while(i--) {
    sum += parseInt(items[i].storeItem.get('Value'));
    }
    chartPanel.descriptionPanel.setTitle('Policy Value $ ' + sum);
    chartPanel.headerPanel.setActiveItem(1, {
    type: 'slide',
    direction: 'left'
    });
    }
    else {
    chartPanel.headerPanel.setActiveItem(0, {
    type: 'slide',
    direction: 'right'
    });
    }
    }
    }],
    series: [{
    type: 'pie',
    field: 'Value',
    showInLegend: false,
    highlight: false,
    listeners: {
    'labelOverflow': function(label, item) {
    item.useCallout = true;
    }
    },
    // Example to return as soon as styling arrives for callouts
    callouts: {
    renderer: function(callout, storeItem) {
    callout.label.setAttributes({
    text: storeItem.get('name')
    }, true);
    },
    filter: function() {
    return false;
    },
    box: {
    //no config here.
    },
    lines: {
    'stroke-width': 2,
    offsetFromViz: 20
    },
    label: {
    font: 'italic 14px Arial'
    },
    styles: {
    font: '14px Arial'
    }
    },
    label: {
    field: 'name'
    }
    }]
    }
    });

    I could not find Ext.chart.Panel in Touch 2.2.1 what version are you using? I also notice some of the configs you were using on your series field and label were different as well.
