Hi Syncfusion team!

After the Grid, I am now trying to use the Chart control, but it
keeps giving me the following error, and I think I added all the
needed references. What could it be?

Hi Artur,

Thanks for using Syncfusion products.

We have analyzed your reported query and found you are missing two references in web.config file those namespace model has the properties of ej:Series .You can fix the reported error by adding below two more references in web.config file.

1.       <add  namespace="Syncfusion.JavaScript.DataVisualization.Models" assembly="Syncfusion.EJ" tagPrefix="ej"/>

2.       <add  namespace="Syncfusion.JavaScript.Models" assembly="Syncfusion.EJ" tagPrefix="ej"/>

We have prepared a sample for your reference and it can be downloaded from below attached file.

Please let us know if you any concern.
