Thank you very much for your help. It was good for my job. I have it 99% completed. I just need the last step. I update the last point well but the crosshair does not update. I have used the length-1 option but the value of x is time and always has the value of the first point before updating. How could I update the crosshair?
I also thought about erasing the last datapoint and adding the new one, but I did not find the instructions to erase a datapoint. Can you give some solution?
Thanks for your help
