Extending or doubling a histogram

I have data that I have plotted into a histogram from around -3 to 3. I want to basically take the histogram and repeat it once to the right, so it will be the original histogram from -3 to 3 and the histogram repeated from around 3 to 6.

Does this make sense and/or is it possible?

I attached the example matrix.

load example x

[N,edges] = histcounts(x,-3:0.25:3);

figure
bar([edges(1:end-1) edges(1:end-1)+6],[N N])

(I assume you mean the new one will extend from 3 to 9, with the same width of 6.)

If x is the data from your original histogram, then the simplest thing to do is probably just replicate the data itself, but translated:

x2 = [x x+6];

and then

figure
histogram(x2)

This adds error because the max*2 is 6.28 and when added is not the exact same data because it adds variation
