Is it possible to create sencha chart in loop?

[Syntona]

Hi I have to create n number of charts.
Can I do like below?

var data = Ext.decode(response.responseText);
var count = data.data.length;
for (var i=0;i<count;i++) {
    rec = data.data[i]; 
  myGaugeChart = getGaugeChart(rec.Value, rec.Name, rec.Nr); 
 GaugePanel.add(myGaugeChart);
}

It is creating chart(as I can see from debugger)
but only the first one is getting display.
Rest of the chart, the id and canvas is there but no chart.

Is this way of preparing chart is correct?
If yes, then what extra I need to do in order to render my chart correctly on the screen?

It all depends on the parent's layout and what getGaugeChart is returning.
