Epidemic Curve Graph

A few weeks back I wrote an article on Grouped Timeline for creating a stacked timeline for onset of different virus.  The idea in that article was to display a stacked needle on a time axis using a HighLow plot. Such graphs are also referred to as EPI or Epidemic Curve

Overlay Bar Charts

A couple of days back, Rick Wicklin forwarded me a link to an article on the BadHessian Blog on creating a Bar Chart using six different freeware packages in R, Python and Julia.   The target bar chart was one produced by the Jetpack stat module with WordPress.  The graph is shown below. The unique feature of

Spirals

Spirals are cool.  And useful.  We use them every day without thinking about it.  Every time the road turns from a straight line to a curve, we go through a transition spiral.  Spirals allow us to change curvature in a steady increasing or decreasing fashion.   Without a spiral, this

The HIGHLOW Plot

SG Procedures and GTL provide you with a large set of plot statements, such as BarChart, ScatterPlot, BoxPlot and more.  You can use them for the intended purpose, and all is well and good.  However, the real fun starts when you leverage a plot to do something that was not

Animation using SGPLOT

Often we want to visualize the relationship between variables over time.  The understanding of such data can be improved by viewing the animated graph over time.  With SAS 9.4, you can create animated graphs using the new animation options on the OPTIONS statement and the PRINTER destination. A popular example an

Report from PharmaSUG 2013

The PharmaSUG 2013 conference in Chicago this week was awesome.  From the perspective of graphics, there was great interest in using SG Procedures, Designer and GTL for building clinical graphs.  It was nice to see many papers by users on how they are using these tools for creating graphs on a daily

Attribute Maps - 1

You created a graph of Response over Time by Severity where Severity has three levels, "Severe", "Moderate' and "Mild".  How do you ensure that "Severe" is always red in your graph, regardless of the data order? Normally, when creating any graph with a GROUP role, the distinct group values are assigned the style

Custom Box Plots

A frequent question we get from users is how to create a box plot with custom whiskers lengths.  Some want to plot the 10th and 90th percentile, while other want the 5th and 95th percentiles.  The VBOX statement in the SGPLOT  procedure does not provide for custom whiskers.  Also, unlike GTL,

Parametric Bar Charts

A parametric bar chart in SG Procedure and GTL parlance is a simplified version of the regular bar chart, where the data is assumed to be summarized prior to its usage inside the SG procedures or GTL.  So, multiple occurrences of the same category and / or group combination is

Mathematical squiggles in SAS

John D. Cook shared a picture of "pretty squiggles" on his blog, as well as a prose description of the mathematics behind it. I'm more of a programmer than a mathematician, but I've attempted to transcribe his description into a SAS program. I used DATA step to generate the point

PharmaSUG 2012 update

PharmaSUG 2012 conference drew to a close today, concluding two and a half days packed with papers, presentations, posters, hands-on demos and super demos by SAS staff.  While the weather outside was a bit chilly from time to time, the conference what hopping with many user papers on how to

Simpler is better

A recent article in the SAS and R blog was about current winter temperatures in Albany, NY.  The temperature data for the recent winter (Dec 2011 - Mar 2012) was plotted on a polar graph. Robert Allison posted an article on displaying the same data as a Polar Graph using SAS/GRAPH .  Here is his

Birthdays among friends

Earlier today, Rick posted interesting information about which time of year the most babies are born, at least in the USA. I don't have data nearly as extensive as what's available at the NCHS, but I do have a sample of birthday records to compare against Rick's findings.  My sample

This list goes to 11

It's almost 2011, so let's reflect on the top 11 posts (by number of visits in 2010) on this blog. Not all of these posts were written in 2010; in fact, some of these date back to 2007. But apparently they are oldies and goodies. 1. SAS 9.2 and SAS
