1. Charts, graphs, and tables provide a great deal of visual appeal.

2. They allow users to quickly spot trends, examine pronounced data, and see an actual picture. This power and appeal makes a “picture worth a thousand words.”

3. In Business Presentation, charts, graphs, and tables can be used to represent data, illustrate important patterns or relationships, and observe changes as data is altered.

A.R.

* Provide a visual representation of data.

* Effectively clarify information.

* Represent many different types of data.

Reasons to create charts and graphs:

A.R.

* Make important trends easily recognizable.

* Allow users to perceive information quickly.

* Aid data interpretation.

1. A pie chart divides a circle into slices to represent a data series

2. The chart depicts each pie slice in a different color for easy recognition of how the individual slice relates to the greater whole.

3. Pie charts work best when you're charting only one data series, when none of your data are negative, when your data features no zero values and when you have seven values or fewer.

1. Bar charts are essentially horizontal column charts.

2. A bar chart organizes the categories along the vertical axis and the values along the horizontal axis.

3. Horizontal bars stretch left to right across the chart to plot the data.

4. Bar charts are excellent for charting multiple values over extended durations, with colored bars representing each value.

1. The chart's horizontal axis presents the categories being charted, while the vertical axis shows the charted values.

2. Vertical columns of differing colors rise from the horizontal axis to visually represent the desired data.

3. The simple presentation and colored columns make for easy visual comparisons.

1. Line charts use one or more horizontal lines to visually depict data points.

2. The chart distributes categories evenly along the horizontal axis and values evenly along the vertical axis.

3. The horizontal line connects the plotted points, providing a clear picture of data trends.

4. Line charts work best when presenting data over evenly distributed time intervals.

1. An area chart or area graph displays graphically quantitive data. It is based on the line chart.

2. Area charts are used to represent cumulated totals using numbers or percentages (stacked area charts in this case) over time.

3. Use the area chart for showing trends over time among related attributes.

4. The area chart is like the plot chart except that the area below the plotted line is filled in with color to indicate volume.

1. An X-Y graph, also called a coordinate graph or scatter plot, is a graph that shows different ordered pairs on an X-Y axis (Cartesian coordinate system).

2. X-Y graphs are used to look at and find patterns in sets of data and to plot mathematical formulas.

3. The points on the graph may form a straight line or a curved line, and may be connected with a line or a bunch of random dots scattered all over the place.

BUSINESS APPLICATIONS OF CHARTS OR GRAPHS* Predict outcomes.

* Illustrate trends.

* Examine patterns.

* Compare and contrast data.

* Investigate phenomenon.

* Collection data.

* Explain outcomes visually.

SELECTING THE RIGHT VISUAL

You are preparing the annual report for your company. What is the appropriate visual (a table, a pie chart, a bar chart, a line graph,) to illustrate each of the following types of information?1. Data on annual sales for the past 20 years.

a table or a line graph2. Comparison of the sales, product by product (there are four

different products), for this year and last year. a bar chart

3. Comparison of your company’s sales figures with sales figures of three competing companies over the past five years a table or a line chart

P.K.

Charts are a good way to visually represent data. Once created, charts can be merged with other technology products to convey an idea, demonstrate content knowledge, and communicate findings.

Remember, “a picture is worth

a thousand words…”
