Marking points

  1. 1 The y-axis has the correct percentage-increase label.
  2. 2 The y-axis scale is 1 cm = 5%.
  3. 3 The E, F, G and H values are plotted at 14, 20, 29 and 70 respectively.
  4. 4 Every bar is correctly labelled E, F, G or H.

Why this answer loses marks

I plotted the bars but left the y-axis as it was.

The plotted heights alone miss the vertical-axis label and a usable scale.
