A large variety of graphs fall in the category of what I call a "Single-Cell" graph. This type of graph consists of a single data region along with titles, footnotes, legends and other ancillary objects. Legends and text entries can be included in the data area. The data itself is displayed
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
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
The SAS 9.4 Maintenance 1 release is now shipping to users. This is great news for GTL and SG procedures users as this release includes some useful new features. Some of these are in direct response to your requests, and others are enhancements that we think you will come to like.
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
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
Last week I covered some of the interesting graph-related papers presented at WUSS. There were quite a few, so I broke up the report into two parts. Here is the second installment. In the paper Creating Graphical Patient Profiles using SAS by William Garner of Gilead Sciences, the author describes how to create
It is always a pleasure to attend SAS user conferences, regional conferences and in-house events. In addition to presenting papers, seminars and super demos to the attendees myself, my favorite activity is to attend presentations by users that include graphical data visualization. These include using SG procedures, GTL, Designer or SAS/GRAPH. This year
In recent conversations with many SAS users at NESUG, SESUG and WUSS, a pattern emerges on the question of creating graphs with SAS or R. Many SAS users are aware of the new graph features in SAS that create high quality graphs with minimum fuss. But, many have not actually used
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.
In the first article on Getting Started with GTL, we discussed the basics on how to create a graph using the Graph Template Language. This involved the creation of a "statgraph" template using the TEMPLATE procedure, and then associating data with the template to create the graph using the SGRENDER
Working at SAS, I consider myself fortunate to have the best employee benefits in the industry. That is one of the factors placing SAS as one of the best companies to work for worldwide, and often THE best company to work for in USA. Given that, I was curious to know the kind
A couple of weeks back I described q way to create a Schedule Chart using the SGPLOT procedure. In that case, I used the HIGHLOW plot to draw bar segments, both for a single and grouped case. A natural extension is to create one with links between each segment. So,
I am happy to report that my new book "Getting Started with the Graph Template Language in SAS" is now shipping. A colleague suggest it would be useful to post some articles with the same theme of "Getting started". I thought that was a great idea, and decided to start a new
Last week Bruno asked about creating a Schedule Chart using SG Procedures. To me, such projects are very interesting and challenging...How much mileage can we get out of the current set of SGPLOT procedure features to create a visual that was not part of the original requirements? The clear choice for
If you have been reading the articles in this blog, you already know that the Graph Template Language (GTL) forms the underlying foundation for all graphs produced automatically from SAS analytical procedures and custom graphs created with the SG Procedures and the ODS Graphics Designer. SG procedures and Designer provide
Yesterday I read a Christina's blog article on the winners of the Best Presentations honor at MWSUG 2013. Two papers caught my (graphical) eye, both by Perry Watts. Perry has done a marvelous job describing how creatively use GTL to make graphs that may not be obvious at first glance.
Some of you may have already noticed the small graphical icon on the lower right side of the blog article labeled "Graphically Speaking Index". Yes, it is a link to a visual index for all articles published in this blog. Well, eventually it will have all the articles. So far, I
A couple of weeks back we had a question on how to make a bar chart with stacked and clustered groups. User also wanted to display the value for each stacked segment below the bars. The article Bar Charts with Stacked and Cluster Groups shows how to create such a
Recently, SAS released SAS Solutions OnDemand for academics. An academic user who is signed up for this can use the SAS Web Editor application to do all their data analysis over the web using a hosted server at SAS. This frees up the user from having to install the software on their own computers,
Creating bar charts with group classification is very easy using the SG procedures. When using a group variable, the group values for each category are stacked by default. Using the sashelp.prdsale data set and default STAT of SUM, here is the graph and the code. SGPLOT code: proc sgplot data=sashelp.prdsale;
Recently my boss came across a graph where a time series plot was modified to include a "thickness" response. We wondered if this would be a good addition to the GTL / SG Series plot statement. What would the result look like, and what are the pros and cons? So, I took up
SAS 9.4 was released a month ago, and we are excited about all the new features in SG Procedures, GTL and Designer. I wrote an article on SAS 9.4 graph features last month, and promised more to come. What then could be better than this Tech Talk video hosted by our
The graphs produced by the SG procedures (and GTL) have a default look and feel designed for the common use cases. However, everyone has a preference for some special features that make the graphs unique. Fortunately, extensive customizations can be made to graphs produced by these tools using statement and
As promised, here is a better combined AE-CM graph, using some of the UI improvements suggested by our UI expert, Riley. His suggestions helped to reduce the clutter in the graph, while still keeping all the features preferred by our users. Click on the graphs for a higher resolution image.
At the SAS Global Forum 2013 in San Francisco, I presented a paper on making Patient Profile Graphs using SAS. You can follow the link to see the graphs presented in this paper. In that paper, I presented ways to create AE, CM, VS and Lab graphs. I discussed aligning the
Last week, I presented some highlights of the new features for SG Procedures and GTL in SAS 9.4. Now, let us dig in a bit deeper. For a plot without a GROUP role, setting an attributes was always easy with SG procedures. All you need to do to set bar color
SAS 9.4 releases today with a ton of new features. As eloquently stated by Craig Rubendall, the driving themes are "Enable. Simplify. Innovate". The same sentiment applies to the ODS Graphics, with a ton of new features for the SG Procedures, GTL and ODS Graphics Designer. In the next few articles,
Recently a user chimed in on the SAS Communities page, requesting a way to add some observation level annotation to a box plot. Wendy was delighted to see a graph created by the UNIVARIATE procedure called "Schematic Plot". In this graph, the box plot of the analysis variable is shown with
A Bar Line graph is commonly used in many domains. The SGPLOT procedure makes it easy to create bar line graphs where the user can customize it in many different ways. This post is prompted by a recent question on the communities page on creating such a graph, with one bar and
