    chart.redraw();

    Another advice is that, if I understand what you're doing, you should keep...

    It should be either:



    var priceChart = new Ext.chart.Panel({

    We're investigating this - I will come up with an answer as soon as we find the issue. I'm not sure if this helps, but we know that memory allocated is relative to the area of the surface used. The...
  18. Hi - One thing you could try is updating the axes right after updating the chart.
