Step 1 of 6
- An empty graph. Each gridline is worth 10 kg.
- Mango: Shop A sold 30 kg. Shop B sold 25 kg.
- Banana: Shop A sold 20 kg. Shop B sold 25 kg.
- Apple: Shop A sold 25 kg. Shop B sold 15 kg.
- Guava: Shop A sold 15 kg. Shop B sold 30 kg.
- The gap for guava is 30 − 15 = 15 kg.
A double-bar graph gives each item two bars, one for each group.
The key is a small label. It says which bar is which group. Here the solid bar is Shop A.
A gridline is a line across the graph. It marks one step on the scale. The scale is the numbers beside the graph.
Both groups use one scale. The apple bar of Shop A ends halfway between 20 and 30. So it shows 25.
The gap is the longer bar minus the shorter bar. Read both bars, then subtract. For apple, the gap is 25 − 15 = 10 kg.
