Hi,

most likely reason for this, is to forget to Control.Invoke (WinForms) or Dispatcher.Invoke (WPF) when updating data from background thread to chart. For correct usage, please see ExampleThreadMultiChannel example in the demo applications.

Hello,

so it seems to be a computer-specific problem. First, make sure all Windows Updates have been installed, and Intel drivers updated.

If the problem doesn't solve, please send us email on support [at} arction.com, and we'll give more detailed support there

My laptop has two video card drivers. Once disabled one, the chart is available now. I don't why. I look forward to get more detail about this problem. thank you!

When an error occurs during object creation, a COMException (defined in System.Runtime.InteropServices) is thrown. The UnknownWrapper class is a helper class designed to be exposed to COM as a VARIANT. When you use the late-binding mechanism, you can avoid this behavior if you pass the parameters as UnKnownWrapper to methods that have parameters of type IUnKnown. The UnKnownWrapper constructor initializes a new instance of the UnknownWrapper class with the object that will be wrapped.
