hi, I am Simulating a model in simulink and want to plot a graph of the output in MatLAB, but when i send it to MatLAB the time range changes, for example, when its in Simulink, its 300 seconds but when sent to MatLAB its 1200 seconds, basically I want the same response from the scope only in MatLAB.

Thanks

Johnny

I suspect you are viewing partial of your curve in Simulink scope. See this post: http://www.mathworks.com/matlabcentral/answers/5591-scope-time-not-shown-to-full-simlation

You may have ploted your curve in Matlab without time so your x-axle is just number of data samples. By default, the simulation time is sent to the workspace as "tout", so try, plot(tout, YourVariable). You can change this by click menu:

Simulation-> Configuration parameters ... -> Data Import/Export

i have generated simulink figure and can convert it in matlab using plot(signal) . now if i want to take the graph between a time limit such as 0.2s t0 0.5s, which command should i write?
