Moynul1 is on a distinguished road
i ve have been trying to plot a velocity against time using a line probe however every velocity against time i plot in the y direction i get the velocity change at 1 second which being my time step rather than the change in velocity form 0-1 sec

i have attached the graph for velocity against time at 11 sec when i want 0-11 sec

and also the line probe.

any help will be greatly appreciated
