Got "Attempted to divide by zero" when change gallery from Scatter to Radar.

[User (Legacy)]

Dear Sir,

I have got a serious system crash problem from ChartFX for .net component

when I change the gallery type from scatter to radar. This problem does not

always happen but you can reproduce it with below code. Seems ChartFX .Net

has some problem to handle the data I input. Please help to fix it.

P.S. My ChartFX .Net version is 6.0.1353.24702.

O.S. is Windows XP professional.

.Net Framework is version 1.0.3705.

Visual Studio .NET 2002 - C# version 7.0.9466

Regards,

James

//Draw scatter plot

chart1.ClearData(SoftwareFX.ChartFX.ClearDataFlag.AllData);

chart1.OpenData(SoftwareFX.ChartFX.COD.Values, 1, 10);

chart1.OpenData(SoftwareFX.ChartFX.COD.XValues, 1, 10);

chart1.Gallery = SoftwareFX.ChartFX.Gallery.Scatter;

double[] arrData = new double[10]{2,0,1,1,11,161,0,0,0,29};

chart1.AxisY.Max = 170;

chart1.AxisY.Min = 0;

chart1.AxisX.Max = 1;

chart1.AxisX.Min = 0;

chart1.AxisX.Step = 0.1;

chart1.AxisX.LabelsFormat.Decimals = 1;

for (int i = 0; i < 10; i ++)

{

chart1.Value[0,i] = arrData[i];

chart1.XValue[0,i] = 0.1 * i;

}

chart1.CloseData(SoftwareFX.ChartFX.COD.Values);

chart1.CloseData(SoftwareFX.ChartFX.COD.XValues);

chart1.Refresh();

//Change gallery type to Radar will get system crash problem.

//Both use code and gallery dialog to change gallery type will get the same

error.

chart1.Gallery = SoftwareFX.ChartFX.Gallery.Radar;

//The error message is list at below.

// An unhandled exception of type 'System.DivideByZeroException' occurred in

system.windows.forms.dll

// Additional information: Attempted to divide by zero.

We were able to reproduce the problem.

It happens because of the X-Axis Scale. Specifically because the X-Axis Step

is < 1.

We will fix this problem and will include a fix in the next service pack.

Thank you for reporting the problem.
