Data is not visible by simulink plot block

Hi...

When I attempt to see my plot in Simulink, it only shows me a specific x-range different than what I had chosen in advance. For instance, I chose "simulation stop time" =1000 but when I see the result from the scope block I can see only the range (980-1000). Why this happens? and how can I fix it?

Thanks in advance

By default, Scope blocks retain only the last 5000 data points to save on memory. If you want all the data to show up:

1. Open up the scope
2. Click the gear button (Preferences/Options)
3. Go to the "History" tab and uncheck the "Limit data points to last" box
4. Run the simulation again to collect the data''

EDIT: If it's not that, there is also a "Time range" option in the first tab of the Scope block preferences. Sometimes this gets changed to values smaller than your total simulation time, so look out for that too.
