In my previous post Diagrammatic Presentation of Data we have discussed different types of diagrams. Now a question may arise in your mind is that how we come to know that which is the suitable diagram in a given situation? Let see how we can answer this.

The choice would primarily depend upon few factors, such as:

1. The Nature of the Data
2. The type of people for whom the diagram is to be made
3. Simple bar diagrams should be used when changes in totals are required to be represented
4. Sub-divided bar diagrams are more useful when changes in totals as well as in components figures are required to be represented
5. Multiple bar diagrams should be used where changes in the absolute values of the component figures are to be emphasized and the overall total is of no importance
6. The multiple and sub-divided bar diagrams are used for not more than four or five components. For more than five components pie diagrams will be the best choice
7. Percentage bar diagrams are better choices when changes in the relative size of component figures are to be displayed
8. The pictogram is admirably suited to the publications of articles in newspapers and magazines or in reports
