GRAPHS
Graphs are used to present data that needs comparison with another type of data. Basically, the two graphs consist of the x-axis & y-axis. The x-axis generally explains the data classification or unit dates being used. Bar Graphs and Line graphs are examples of such visual forms.
The merits are as follows:-
- Comparison or trends are easily shown.
- Main tilters and subtitles for data easily added.
- Oral presentations possible, if simple in form.
- Colour and variety add to visual appeal.
The demerits include:-
1. Inclusion of too much detail may confuse the reader/ listener.
2. Precise distinctions between variables harder to see
3. Not all headings consistent between graphs on x and y axes.
PIE Charts
When you wish to show relative sizes of various categories and the percent each category adds to the whole, pie charts are the most popular and helpful. To make a comparison of facts easier, the pie segments (pieces) may be shown with percentages-all placed consistently either within a slice or outside but near it.
The merits are as follows:-
1. Segment of pie may be lifted out for visual emphasis.
2. Parts of a whole may be shown.
3. Values, headings, legends may be placed below, inside or aside data.
4. Both oral written presentations can be use pie charts.
The demerits include:-
- Precise distinctions are not visible when decimal distinctions are needed
- Use of too many parts and values may blur distinctions.
- distortions may occur if similar patterns are next to each other
