Integraor ploting

 Dear sir, 

May I know how to plot graph of an integrator. The term to be integrated is the numerical value '2' and time interval is 0 to 4 sec. I want to plot fo every second.

Thank you. 

Taxonomy upgrade extras: 

Can you give an example that you want?

 Well input voltage Vin=2. I want to integrate this input for time t=0 to 4 with respect to dt and need to plot output voltage Vo at each time interval,i.e at t=0,1,2,3,4.
