Steps

1. Set cumulative totals for the data each year

2. Draw vertical axis(Y) to represent dependent variable

3. Draw horizontal axis(x) to represent independent variable

4. Label both axis using suitable scale

5. Plot the cumulative values for each year

6. Use values for components to subdivide the cumulative bar

7. The subdivisions are placed in descending order with the longest at the bottom(coffee)

8. Shade each component differently

9. Put title and key

Advantages

1. It’s easy to construct

2. It has good visual impression

3. There is easy comparison for the same component in different bars because of uniform shading

4. Easy to interpret because bars are shaded differently

5. Total value of the bar can be identified easily

Disadvantages

1. It doesn’t show the trend of components (change over time).

2. Can’t be used to show many components as there is limited space upwards

3. Tedious as there is a lot of calculation work involved.

4. Not easy to trace individual contribution made by members of the same bar

5. Poor choice of vertical scale causes exaggeration of bars length leading to wrong conclusions
