Make sure you are calling the ChartView.SetLicensePath in the main Form of the program, as done in our example program LinePlotSalesVolume. It must be called BEFORE the ChartView derived class is instantiated, which in this case is done in the InitializeComponent call.
Public Sub New()
MyBase.New()
ChartView.SetLicensePath("LinePlotSalesVolume")
'This call is required by the Windows Form Designer.
InitializeComponent()
'Add any initialization after the InitializeComponent() call
End Sub
And that your project is generating an application program, not some sort of control. If the LinePlotSalesVolume example program works, but yours doesn't, you need to study the differences between the two programs.
If these hints don't help you will need to send us the complete source to the simplest possible version of your project that reproduces the problem, as a zip file, so that we can compile and run it in our offices. Send it to support@quinn-curtis.com. Include your company information and when you purchased the software in the e-mail.
