Hello Victor,
The reason why the the control is doing this is because you are not load the file correctly.
Try this
namespace ExcelTestWpf
{
public partial class MainWindow
{
public MainWindow()
{
InitializeComponent();
'sets the control to workbook
var workbook = ExcelViewer;
'loads the Excel file into the workbook
workbook.Load(@"D:\test.xlsx", IO.FileFormat.Excel2007);
}
}
}You can get more information from Excel file format

Thanks Shane. And Thanks victororlov82 for the test file and code. There is really a problem when Chart loaded from Excel file. ReoGrid cannot read serial labels and all text of serial label is null, when drawing the chart ReoGrid crashes because of null text.
It will be fixed in next release. Thanks for reporting!
