Plotting with variables seems not working ?

I am not able to plot the data's through the plot function and as well as from menu option also, can any one please give some solution?

@Vaishnavi Mohan: what have you tried so far? What happens: do you get an unexpected output, or no plotted data shows on the figure, or you get an error message, or MATLAB goes into a hanging state or infinite loop, or does your computer catch fire? Should I call the fire brigade?

If you want help then you need to give more information about what you have tried and what you expect.
