I was inspired by this post by the Excel gurus at Chandoo.org to emphasize the importance of smart legends in charts.
What are smart legends? Well, legends do more than label your data. They can also be used to quickly summarize your message.
Look at this chart, showing U.S. tax revenues and expenses for the past 20 years, using the Excel default legends.
Not bad. Very clean. But you can do better if you use smart legends to summarize your key points.
Look at this updated chart, demonstrating the use of smart legends.
Smart legends summarize the key points in your data, using text, numbers and symbols. You can be creative in your use of smart legends.
