            });
        }
    });
    but there is something strange happening, its plotting wrong values on the charts

    here is a screenshot of the chart

    http://www.tiikoni.com/tis/view/?id=8f0c0ea

    its reaching up to 10000 and actually, this value doesn't exist..

    any help would be appreciated..
