MATLAB: Extending or doubling a histogram

histchistcountshistogram

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])
