Graphics

Graphics mean more than graphs;they include photographs,diagram of assembly,grapha of foreign debt,pictures of places and cartoons.
Graphics help to sort,classify and group data such as percentages,numbers and rates of change.They use visual techniques to focus the readers' attention on the main points and to clarify discussion and findings.
Formats of Grapics
Usually have the following elements:
1.Date and information that covered in graphics
2.A label that describes the graphics
3.The source of information

Types of Graphics
Concepts,relate data,movement and changes in time and comparisons call all be shown graphically,so a range of graphics is available to the writer.
1.Tables
Tables present data in parallel lists or colums they can compare large amounts of data in an easy way and emphasize similarities or differences.


2.Line Graphs
Line Graphs show movement through time,their main purpose is to indicate trends. On line graphs,data are plotted as points connected by segment of a line,which shows a relationship between the variable.A line graph with only one line is known as a simple line chart,if it has several(ususally, limited to three or four)lines it is called a multi-line chart


3.Pie charts
Pie charts compare with parts of a whole unit;They show the parts or divisions of a whole unit in a circle.For a circle,they are called sectors or segments.


4.Column Graphs
Column graphs show changes from one time period to the next ,or to compare on item with antoher. There are vertical bar graphs and horizontal bar graphs,which can be single or grouped.


5.Summary
Table Advantage:Allows comparisons between large amounts of data Disavantage:Difficult to connect data quickly
Line Graph Advantage:Indicates clearly movement and trends in data Disavantage:Inappropriate labels and scales can make it difficult to interpret
Pie Chart Advantage:Shows relative proportion and importance of each part to the whole unit Disavantage: Difficult to judge differences between area and size
Column Graph Advantage :Simplifies comparisons between items or periods Disavantage:Size and proportins can be hard to interpret


Writing Points
Some important writing techniques for greater effectiveness:
1.Select a proper form of graphics
2.Keep the graphic simple and easy to follow
3.Label the graphic and give the source of information clearly
4.Graphics and text should be intergrated
