Flip the histogram

ROOT
1

I am using the 1D histogram to show the noise of each strip of our Si sensor, which has 32 strips. Our strip number 1 starts from
right hand side and 32 is on the left hand side.

I am wondering whether there is a way to flip the histogram.

I do not know if it will help you, but the attached macro plots the X axis in the reverse way.
