Charts and Tables
Charts and tables are useful for compiling and cross-referencing larger amounts of information. The combination of rows and columns allows you to create headers and then divide them up into units, categories, dates, and so on. Medical information is put into charts so that periods of recorded information, such as vital signs, can be updated and scanned by doctors and nurses. Charts and tables are also good for combining text and numbers, and they are easy to make with word processing software like Microsoft Word or spreadsheet software like Excel. Think of presenting your department’s budget and spending at the end of a business quarter. You could have headers in the columns with the various categories and itemized deductions in the rows ending with a final total for each column.
A pie chart is an alternative representation of textual and numerical data that offers audience members a visual representation of the relative proportions of a whole. In a pie chart, each piece of the pie corresponds to a percentage of the whole, and the size of the pie varies with the size of the percentage. As with other charts and tables, most office software programs now easily make pie charts.
