Hi Otsile Kesianye,
Thanks for using Syncfusion products.
The "Argument Exception" attached in the screenshot will occur if "Syncfusion.Chart.Base" and "Syncfusion.Chart.Mvc" assemblies are incompatible. For an MVC5 application, we should use "Syncfusion.Chart.Mvc" assembly with version "11.4500.0.26" and "Syncfusion.Chart.Base" assembly with version "11.4500.0.26".
Please let us know if you have any concern.
Regards,
Anand
