Hi, I am currently using the evaluation version of the Nevron chart control for ASP.net. I need to show a bubbles chart, where in the size of the bubbles will change say every 2 secs. I have managed to implement the same. But the problem that i am facing is that the bubbles size doesn't remain consistent with the values provided to it,  even after giving values which only increase every 2 secs, the size of the bubbles keeps increasing and decreasing, which should not happen according to the values provided for the bubble size.

If I plot say 6 bubbles and try to update the size of these bubbles every 2 s, the size of the first and the last bubble stays constant and doesn't change, whereas the remaining 4 bubbles size increases and decreases. This behavior suggests that the size of the bubbles increases and decreases relative to the size of the first and the last plotted bubble.

 Please let me know how to control the size of the bubbles and how to correctly set the bubble size. I am using the below code:-

public override void OnAsyncRefresh(string webControlId, System.Web.HttpContext context, NStateObject state, EventArgs args)
   {
    NChartSessionStateObject chartState = state as NChartSessionStateObject;
    NRootPanel rootPanel = chartState.Document.RootPanel;
    NBubbleSeries bubblechart= (NBubbleSeries)chartState.Document.RootPanel.Charts[0].Series[0];

...

...

bubblechart.ClearDataPoints();

...

bubblechart.AddDataPoint(new NBubbleDataPoint(15, value, "value1"));

}

Thanks
