Martyn- Your decimal number fields had the decimal places display setting set to 0, effectively rounding the display, but not the value itself. I have changed the decimal places display setting to Auto, so you can see the full decimal values. I also turned off the number abbreviation option in the Bar View, so you can see the magnitudes. If you intend to round these decimal values to integers, use a Formula field to do this and change the data typing for the calculated column to Integer.
