The units are weight in lbs. The greatest value is 10.5 and the least value is 6.9

Using graph paper, start with 1 box = 1 unit.

Mark each rectangle along the scale. Label the marks by the units they represent. Then decide how wide each bar should be.

In the graph above, each grid line going from bottom to top represents a multiple of 0.5.

Each small rectangle in the graph below represents 0.5 units. So to draw a vertical bar that represents 6.9 lbs, divide 6.9 by 0.5. Your quotient is a bar height of 13.8 rectangles. Thus the bar for Charlie is 13.8 rectangles in height (and represents 6.9 lbs). To draw a bar that represents 10.5 lbs, divide 10.5 by 0.5. Your quotient is a bar height of 21 rectangles. Thus the bar for Sarah is 21 rectangles in height (and represents 10.5 lbs).
