Dear all,
what does the arrow and the "3x" mean in this figure?

Thanks a lot

It looks as if it means that the intensity of all the peaks to the right (that is, m/z above about 160) is multiplied by 3 for the sake of clarity. So e.g. the 211 peak really has a height of 17 rather than 51, relative to 127 = 100.
