What do you mean? Do you mean like you have a bar chart of the counts and you'd like to superimpose a smooth line/curve plot (like a Gaussian or something) on top of the bar chart?

If you want to plot something on top of your histogram, use
hold on
plot(your arguments here)
If you want to plot the histogram as a curve, use
H = hist(whatever);
plot(H)

Try
[hi cx] = hist(H);
plot(cx, hi, 'r', 'LineWidth', 10)
What are the following commands showing you?
subplot(1,2,1), hist(H)
subplot(1,2,2), plot(cx, hi)
