I want to plot exponential signal that is euler formula exp(i*pi) in MATLAB but output figure is empty and does not shows graph as shown in attached, even i tried plotting simpler version, i mean
exp(i*pi),but still figure was empty

There is an example of plotting exponentials in the documentation here, see the sub heading Plot Exponential Function. If you're trying to observe a single point on the plot you could also write
plot(y,'or')

The plot function plots lines between points. You have only one point, so if you change the plot call to:
y = exp(100*i*pi)
figure
plot(y,'p')
plots a star at (1,0).

Add a time-varying vector:
t = linspace(0,2);
y = exp(100*i*pi*t)
y = cos(100*pi*t)+j*sin(100*pi*t);
and now the results will go from 0 to .
To see it:
figure
plot(t, real(y), t, imag(y))
grid
The two ‘y’ vectors are the same, so this works for either one of them.
