Hello everyone!

I am using Chart FX chart control in the web part. I am also getting the
same error when trying to add the web part in the Sharepoint portal server's
web page.

"Web Part Error: One of the properties of the Web Part has an incorrect
format. Windows SharePoint Services cannot deserialize the Web Part. Check
the format of the properties and try again."

If I remove the Chart FX related code then this is working fine. I am
getting proper output when applied the same code in a ASP.NET web
application. I am trying the same code in the web part, but i am getting
this error. I am submitting the code for your reference.

Can you guys help me to solve this problem?

My best guess is that ChartFX is trying to save something to view state that is not serializable. My best guess is that it is the data source for your chart.

It is out of your reach where the error is occuring. My best suggestion is to contact their support and tell them that they have a problem persisting data to view state :-) .
