Can anyone help me understand how to interpret the y-axis of a Molecular Weight Distribution Plot? The label on the plot is dwt/d(logM)or dw/dlogM. I have read this is a differential weight fraction. If this is a weight fraction why doesn't the axis scale range between 0-1? The scale on several plots I have seen ranges between 0-2.
