Below, I've plotted an arbitrary function between arbitrary limits, -5 and +37.

%%
x = linspace(-5,37)'; 
y = erf(x/20); 

subplot(2,1,1); 
hp=plot(x,y)

Now you asked for the x-axis to be in percentage. That's a little ambiguous, so I've intrepted that to mean percentage of the lower x-limit to the upper x-limit. (Note: that may not be what your data lies between.) I've used xlim to get those values.

xl = xlim; % lower & upper limits of the x-axis scale above. 
xperc = (x-xl(1))/diff(xl)*100 % convert to % 

subplot(2,1,2) 
plot(xperc, y)
xlabel('x [%]')
