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,

Did you make sure the request is actually being made? Don't see why it shouldn't though. Also, is the data different?

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();

i have the same issue on stockapp example, i want to add values to the chart on runtime
i successfully add to the store but the chart never display the new added values
i use this line to add to the store
Ext.getStore('Apple').add({date:datevar,open: 583.4, high:590, low:583.1, close:587.41,volume: 12896200,adjClose: 587.41});
and i check the record is added by this
console.log("count"+Ext.getStore('Apple').getCount( ));
and it is added successfully
and when i call Ext.getStore('Apple').refresh(); it throws
Uncaught TypeError: Object [object Object] has no method 'refresh'
