The answer should become evident when you understand the answer to your other question.

First, you should define everything:
h = 6.25 * 10^(-34);
x=1:100;
y=h.*x;
Plot(x,y)
So here you first define your h, then points in which you will plot your function (here x=1,2,3,...,100), but if, say, you want to plot your function from -5 to 5 with step 0.1, you write x=-5:0.1:5, so in this case x=-5,-4.9,-4.8,...,4.9,5.
After that you calculate your y points according to your formula and plot it.

h=6.25*10^(-34);
x=-10:10;
y=h*x;
plot(x,y)
grid on
