An example of a chapati chart showing different dimensions of health systems is shown in the box. The segments, or spokes of the wheel, can be used to reflect different issues being measured. Discussion is held amongst the group involved and the line in the segment is drawn to reflect the extent of participation on that dimension, closer to the hub where participation is low, and to the rim where it is higher. The same chart can be used to reflect changes before and after interventions, or to show variations in participation between different groups, or differing perceptions of different groups.
