Capitalization Capitalize proper nouns only. Proper nouns are the formal names or titles we give to people and things, such as positions, organizations, committees, companies, forms, and documents. Always capitalize the first and last word in a heading or title. For rules on capitalizing hyphenated words in headings, see Hyphens . Avoid using all upper case in a manual, except for short acronyms.
Charts Use charts and graphs to present quantitative information.
Some of the most common types of charts and graphs are scatter charts, line graphs, pie charts, histograms, and bar graphs. Charts can show the values of numerical data, changes or trends over time, patterns in data, and relationships among various factors. When using charts or graphs, make sure they are easy to understand, and that they mean the same thing to your readers as they do to you. Keep the chart simple and concise. Effective charts direct attention to the data's significance, not the chart's form or style.
