Why is there a blank zone at the start of my simulink simulation?

I am quite new to Simulink and am trying a simple RL circuit to test it out. When I try to run the simulation for say 10 sec, in my scope (the output) the signal is blank (not zero just blank) for first 8 seconds and then there is the signal. If I change the total simulation time to say 5, the blank area is around 1 sec.
Is this inherent problem of Simulink, or am I doing something wrong?
NB: A colleague suggested that the blank time is the time Simulink is trying to solve the problem and after solving, it starts to show the results. I haven't seen any other simulation software that cannot give an output at time 0.0.

Probably in your Scope block, you have a parameter checked. Go to Settings->Logging and uncheck Limit data points to last parameter then rerun the simulation.

Thank you for the help. It was a push in the right direction. Apparently in my version, (R2014a) it was in Setting -> History
Thank you for the help.
