    Default Answered: Reload chart datastore

    Answered: Reload chart datastore


    Using Beta 2.1 with charts.

    I'm using a simple data store that generates random data. I would like to refresh my line chart with this data, but so far had no success in this. I have tried:

    Ext.getStore('mystore').load();

    But nothing happens on my chart at all. However, this is working:

    Ext.getStore('mystore').removeAll();

    Great, so I can remove all the data from the chart. But how can I load it again and refresh the chart?

    Thanks,

    Try adding something like this inside your store definition:

    refresh : function()
    {
    // Generate a fresh set of random values for display on the chart
    var newData = generateData(5,1);

    // Update this store's data field, which will cause a chart refresh
    this.setData(newData);
    }

    Then hook up a UI button to call this refresh method:

    var store = Ext.getStore('myStore');
    store.refresh();
