I bet a lot of SAS users know where the phrase "Live Long and Prosper" comes from ... but can we use SAS software to also help analyze 'how long'? This blog posting shows several different kinds of SAS graphs that can help answer such a question!

As you can see, there are many different ways of visually analyzing the same (or in this case similar) data. Each different type of chart, and even subtle variations of the same chart, can help give you more/different insight into your data, and thereby help you understand it better. When you're exploring your data, I encourage you to visualize it in several different ways. And when you want to answer a specific question, select the type of chart that best answers the question.
