COM 295 Week 3 Practice Case Analysis: Evaluating Charts for a Presentation Complete “Case Analysis: Evaluating Charts for a Presentation”� in Connect. Evaluating Charts for a Presentation You should generally evaluate your charts in terms of the following: title descriptiveness, focal points, information sufficiency, ease of processing, and take-away message. Title descriptiveness. Most readers look first at the chart’s title to grasp its message. Thus, the title should explain the primary point of the chart. However, it must be short enough for the reader to process quickly (generally fewer than ten words). Focal points. A chart should draw the reader’s attention to the most critical relationships and ideas. Each of the chart’s focal points should support one main idea. The focal points can be visually generated in many interesting ways, including font choices (bold, italics), color, size, and callout boxes. Information sufficiency. Charts should contain enough information for the reader to quickly and reasonably understand the ideas that are being displayed. Clear labels and legends should demonstrate what is being measured and in what units. In some cases, readers will expect to know data values at each point within the chart. Ease of processing. A basic purpose of a chart is to convey complicated information as quickly as possible. By selecting only the necessary information and placing labels and data at appropriate places, you enable your reader to process the information quickly and efficiently. Ideally, your reader should grasp the key ideas within 10 to 15 seconds. Take-away message. An effective chart leaves a lasting impression about your key point. The take-away is the essence of your chart”�how the information, title, focal points, and other formatting combine to convey a lasting message.
