Reload the data of a chart on tap / click (for drilldown purpose)

[Jem]

Hi,

There's a piechart I must "reload" the data on tap.

The screen shows an "overview" piechart. Each slice shows the sum of sub items. Tapping a slice must reload the pie chart, showing this time its details.

        var chartPanel = new Ext.chart.Panel({
            title: 'Pie Chart',
            items: {
                cls: 'pie1',
                theme: 'Demo',
                store: store,
                interactions: [{
                {
                    type: 'iteminfo',
                    gesture: 'tap',
                    listeners: {
                        show: function(interaction, item, panel) {
                            // doing stuff

iteminfo will always popup a frame, in which the "show" listener's handling function may write data.

I would like a type that simple exectues code.
What could that be? Reading the API gave me a series of interactions, but none seem to help. Maybe I don't proceed the right way to perform this drill down?

Why not make your own interaction? In the onGesture method load the store instead of showing a panel or something

Why not actually? I removed it but it seems to work the same way and the documentation gives the following example:

    new Ext.chart.Chart({
        renderTo: Ext.getBody(),
        width: 800,
        height: 600,
        animate: true,
        store: store1,
        shadow: true,
        theme: 'Category1',
        legend: {
            position: 'right'
        },
        axes: [ ...some axes options... ],
        series: [ ...some series options... ]
    });
