Find out what 'holiday' your birthday is on!

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

Creating 'pretty' maps with SAS

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

Data-driven Layouts in R's ggplot2 and ODS Graphics

Following Sanjay's cue (see “R U Graphing with SAS”), I tried creating data driven multi-cell graphs using R. I played with the lattice and ggplot2 packages. I found ggplot2 simpler to understand and use than lattice, but there are probably some trades offs. Data-driven layouts are referred to as 'faceting'

Plot Layering for Bland-Altman Graph

Recently a user new to GTL and SG procedures asked how to create a Bland-Altman graph on the SAS Communities site. He included an image of the resulting graph to indicate what he wanted, I described to him how that graph can be created, but since he is new to the art

Broken Axis

In my previous post I described the new Polygon plot statement that is included with the SAS 9.4M1 release. So, a valid question is - what is my motivation for discussing the new features in SAS 9.4M1 when most users are at SAS 9.3 or SAS 9.2 versions? Here are a

Survey Charts

Often we have situations where the category values on the graph have long character strings. This is often the case when graphing survey responses to questions. The questions may be sentences, sometimes moderately long. With SAS 9.4, GTL and SG now support the ability to display tick values split over

How to plot a forecast and confidence interval

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

Grouped Bar Chart with StatisticsTable

Creating a Bar Chart with a table of statistical data aligned with the bars is a popular topic. With SAS 9.4, creating such graphs gets easier with the new AXISTABLE statement in GTL and SG procedures. But some use cases can flummox the latest gizmos. Such is the case I ran into recently. Here

When did you first use SAS?

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

Comparative Histograms

In reference to a previous article on Violin Plots, a reader asked about creating comparative mirrored histograms to compare propensity scores. While I had my own understanding of "Mirrored Histograms", I also looked this up on the web. Google showed many cases of two histograms back to back, either horizontally or vertically.
