Partial plot in the same figure

Hello,

Say i have an array of ap[10] and ap2[10]. i want to plot partial with respect of plot(t,ap) and plot(t,ap2) in the same axis where t=22. the first ap will start from t=0 until t=10, where t=11 & 12 is blank. then ap2 will continue to plot from t=13 until end.

is it possible to do so?

thanks

Not positive I follow precisely, but taking a guess of what you mean...excepting you're got a disconnect in that if length(ap)=10, then the number of values between 0:10 is 11 unless you use

t1=linspace(0,10,0);  % rather than 0:10

But, on the assumption really want 1:10 to go with the 10 values,

plot(1:10,ap,'k-')
hold on
plot(13:22,ap2,'k-')

will do it. Or, a little more elegantly, perhaps would be

y=[ap nan nan ap2];  % assume are row vectors
t=[0:length(y)-1];   % a time vector
plot(t,y)

The NaN in the vector y will not be plotted but the time vector increases unbroken.

thank you for the solution, i never thought it would be this simple...

but, slight problem with value for x axis, i already set it with

q=0:0.15:3.15; %time

so, how can i change it to these?

thanks

The simplest is to use q instead of t as the independent variable with the y vector as above.

plot(q,y)

ok.thank you.
