# MATLAB: Won’t one of the plot points show

plot

In this figure h_t won't show itself
 x = 0.5  f = exp(-0.5*x^2); t = 0.5; g_t = exp(-(x-3*t)).^2;  h_t = exp(-x.^2+t).^2; figure hold all plot(f,'r') plot(g_t) plot(h_t,'g') xlim([0 2])  grid off
I've tried h_t outside on it's own and it gives a point but it won't show on this figure.
And is there a way to make the points bigger or easier to see?

 figure hold all plot(f,'ro') plot(g_t,'bo') plot(h_t,'go') xlim([0 2])  grid off
