Export chart giving "Parameter is not valid" exception

[dipti]

I am using charFx 7.

Sometimes when i export my chart it gives a error "Parameter is not valid". This behaviour is random i.e. for some charts it gives this error.

chart.objChart.Export(

FileFormat.Bitmap, System.Web.HttpContext.Current.Server.MapPath("ChartImages") +"\\" +img);

Please help me with the solution

 

Thanks & Regards

Dipti

I've had this error with certain gallery types when the image size specified is too small for the chart.

I still have the support ticket open, they've not gotten back to me after saying they could re-create the error.
