What is the "same" that you are asking for? Which variables do you want to be fixed in the plot and which do you want want to change? If you have more than one changing variable then which do you want for x, which for y, which for z?

Adding an infinite number of terms takes an infinite time, and there is never a "finally" for an infinite time.

You can plot for various values of t between 0 and 1.
t=.3%not sure what you want to plot against, I held t constant and plotted N vs. error
n=1:2:100000;%have to pick something for infinity (100,000 should be good for about 5 decimal places)
N=1:2:500;%whatever you want N to go up to
x=(4/pi)*sum((1./n).*sin(n*pi*t));
e=arrayfun(@(y)x-(4/pi)*sum((1./(1:2:y)).*sin((1:2:y)*pi*t)),N);
plot(N,e);

by having some values for x and t. such as
x=0:h:1;
t=0:k:0.06;
