Robert has worked at SAS for over a quarter century, and his specialty is customizing graphs and maps - adding those little extra touches that help them answer your questions at a glance. His educational background is in Computer Science, and he holds a BS, MS, and PhD from NC State University.
Every day of the year is an official 'national day' for something - here's a SAS chart to help you find which bizarre 'national day' falls on your birthday! I recently read an article that lists weird and unconventional national days. It was very interesting, but I found the data
When you create maps, you are typically plotting data for analytics -- but you can also use SAS to create 'pretty' maps for background decorations (for posters, slides, presentations, etc). This blog shows you a few examples... A few years ago I noticed that the CNN Situation Room had a decorative
The farther you try to forecast into the future, the less certain you are -- how can you represent that graphically? One way is to draw a shaded/colored "confidence interval" around your forecast line, but this is something a lot of SAS users have trouble with. That's why I decided to create
Data on punched-cards, SAS software delivered on tape, jobs in the queue on the mainframe, printouts on green-bar paper ... we really appreciate all our SAS users, but if any of the above are part of your "SAS memories" we especially appreciate you! I guess I'm a computer geek, because
There are 2 kinds of people in the world -- those who dread change, and those who look forward to it. Which kind of person are you, when it comes to upgrading your SAS software?!? With most software (such as Windows OS, Facebook, Gmail, etc) I tend to fall into
I'm always trying to find new uses for SAS - this time I've written a proof-of-concept that shows how you might use SAS to create charts that test for color blindness. If nothing else, I think it's a fun example :) First, I did a Google search, and looked at several
SAS 9.4 allows you to create html5 output with your graph inline (as part of the html), providing a great way to email your SAS/Graph output! Previously, if you used ods html and dev=png to create graphs, you had to deal with two files -- a png file (containing the graph)
SAS has been used to track the spread of many things, such as wild animals, tornadoes, and money launderers -- but this time I'm using it to track the spread of Walmart stores across the U.S. over time! Since its start in the 1960s, Walmart has grown to be the largest
Many people today just use their computer to play Angry Birds or post pictures of their most recent meal on Facebook ... but what would some of the great minds of the past have done with a computer?... For example, Charles Minard was creating impressive information graphics without a computer over 100 years ago,
This graph certainly makes it clear! I can see right through your lies! Clearly, you know what you're talking about! We need more transparency in our organization! What was that all about, you might ask?!? ... I was just getting all the obvious puns out of the way, so I
As you've probably guessed, I'm a "visual" person - I like to see things (in a chart/graph/map) rather than just reading about them (in a data table and summary statistic). Don't get me wrong - I'm a big fan of statistics and analytics -- but I'm an even bigger fan of
"It slices, it dices ... it helps test laboratory mices!" In a joking way, this is a perfect description of SAS software, don't you think!?! :) And to prove it, this blog contains a collection of 32 examples, showing a variety of ways SAS can be used to graph data
"It's a floor wax, and a dessert topping" - this pretty much describes SAS/Graph! (bonus points if you know where this quote came from!) Some people think of SAS as just a quality control tool. Others think of it as just a sales & marketing tool. And yet others think
Your biggest problem with maps used to be learning how to fold a paper road map. Today, with the advent of GPS, Google Maps, and location-specific data, the bar has been raised! ... you now need to know how to plot your data on a map! Below are several examples of different kinds
There's an old expression "easy as pie." Have you ever tried to bake a pie??? ... It's not so easy, LOL! And neither is using pie charts correctly! :) Below are several examples of different kinds of pie charts you can create with SAS/GRAPH. And at the bottom of this
Do you know how to create a bar chart using SAS, and when to use what kind of bar chart?!? If the answer doesn't come to you "easy as pie" then this blog is for you! Below are several examples of different kinds of bar charts you can create with SAS/GRAPH.
Do you know (right off the top of your head) the simple SAS/GRAPH code you would use to create line graphs? ... If not, then this tutorial is for you! A line plot is basically a scatter plot where the markers are connected. A line plot should only be used
Scatter plots are probably the simplest kind of graph, and provide a great way to visually look for relationships between two variables. But, do you know (right off the top of your head) the simple SAS/GRAPH code you would use to create them? ... This tutorial leads you step-by-step through the
ODS graph styles provide users with an easy way to control things such as the colors and fonts used in a graph, freeing the user from having to specify these properties in their code. A lot of thought was given to picking colors that work well together, and look good. The
To say that I'm excited about the SAS 9.4 release is an understatement! For example, did you know that in SAS 9.4, you can write SAS/Graph output directly to a Powerpoint slide?!? This is definitely an item that was on my "wish list," and will no doubt make life a
SAS 9.3 already has smooth (anti-aliased) lines in SAS/GRAPH device=png output, and in SAS 9.4 you will also get smooth lines in your device=gif output (and gif animations)! Woo-hoo!!! Here are a couple of simple examples to demonstrate: The first example is device=gif Proc Gmap output. If you look very closely, you'll notice that
They say "Imitation is the most sincere form of flattery"... Therefore when I imitate Hans Rosling's famous world-data animation, it's not that I'm jealous, but that I'm paying homage to him! (OK, and maybe also a little bit jealous! LOL) Well, anyway, for those of you who haven't seen it,
I recently read an interesting article in The Economist, where they describe "The Big Mac index." This is an index they invented as a lighthearted guide to compare currencies in different countries. In their article they create a multi-panel display (similar to a dashboard) where they compare the index for several countries using
Are you an NFL fan, or curious about analyzing social media data? -- Well, in either case, this blog's for you! I recently read a fascinating Facebook article that included a U.S. county map showing which NFL (U.S. football) team had the most 'likes' in each county (based on ~35 million
I haven't seen an official definition of 'infographic' that I really like ... but in my mind it's something 1/2 way between data visualization & artwork. It borrows elements from graphs & dashboards, and combines that with an artistic poster. If you perform a Google image search on infographic you'll see
A big part of "winning" these days (be it sports or a business) is performing analytics better than your competition. This is demonstrated in awe-inspiring fashion in the book (and movie) "Moneyball." And on that topic, I'd like to show you a few ways SAS can be used to analyze sports data
I've heard many customers ask "Can SAS do/use/handle census block maps?" My answer was "of course!" ... but I never really had any examples to show/prove that. Well, now I do! :) First, you need to locate & download the shape files for the census blocks you're interested in plotting. For
I'm sure that most of you have seen the really cool interactive Baby Name Voyager, right? If not, go have a look and try it out (be sure to plug in your name, and the names in your family, and so on). Here's a screen-capture: That's a pretty cool application! ...
What are the odds of winning the lottery? This seems like a simple question (and yes, there is a simple answer), but there are a few technical details to work out first... Which lottery? Let's say the Powerball Lottery. When? The number of balls used in the Powerball lottery has
I like to think that I have a graph for all occasions - Chinese New Year is no exception! ... The exact date of the Chinese New Year varies from year to year, because it's based on the lunar (moon) cycles. I thought it would be useful to create a
