Question be solved by Boian Mitov-The PlotLab Auther. Because the PlotLab used non managed thread, is thread safe. But we need to use non managed thread or UI thread set data.

1. this.dispatcher.Invoke

2. using TimingLab.ClockGen class import Mitov.TimingLabBasic.dll

   codeExample: ClockGen clockGen = new ClockGen(); clockGen.Mode = ClockMode.FullSpeed; clockGen.Clock += ClockGen_Clock; clockGen.Start();

   private void ClockGen_Clock(object sender, EventArgs e)
   {
       // Do you data set 
   }
