ArithmeticException problem !!!

[User (Legacy)]

Hi,

I need your help please.

I´m using the commercial ChartFX_7.0.2330 to create a real time chart. I use 

this function to reset my chart:

private void ClearHpsChart()

{

     chartHPS.Data.Clear();

            chartHPS.RandomData.Points = 1;

            chartHPS.RandomData.Series = 2;

            HpsSeriesAttributes = new ChartFX.WinForms.SeriesAttributes();

            AvgHpsSeriesAttributes = new 

ChartFX.WinForms.SeriesAttributes();

            HpsSeriesAttributes.Color = 

System.Drawing.Color.FromArgb(((int)(((byte)(192)))), ((int)(((byte)(0)))), 

((int)(((byte)(192)))));

            HpsSeriesAttributes.Line.Width = ((short)(1));

            HpsSeriesAttributes.Text = "Hits per Second";

            AvgHpsSeriesAttributes.Color = System.Drawing.Color.DarkCyan;

            AvgHpsSeriesAttributes.Gallery = ChartFX.WinForms.Gallery.Curve;

            AvgHpsSeriesAttributes.Line.Width = ((short)(1));

            AvgHpsSeriesAttributes.Text = "Average (5 mins)";

            chartHPS.Series.AddRange(new ChartFX.WinForms.SeriesAttributes[] 

{ HpsSeriesAttributes, AvgHpsSeriesAttributes });   // <--     Here i get 

the System.ArithmeticException

            InitializeHpsChart();

}

Now, this works great until i use some saveFileDialog in my application. If 

i´m saving some file using this dialog the next time the funtion is executed 

i´m gettings System.ArithmeticException (in the line 

"chartHPS.Series.AddRange") ! I know this is strange since the dialog got 

nothing to do with the chart code but maybe the dialog changes some 

environment variable that causes the library to throw an exception.

Please help me,

thanks

This is very strange, I cannot imagine what relationship the File Dialog may 

have with this code.

I was unable to reproduce this problem on my side. Please post a sample 

program that reproduces the problem.
