Micro Maps

MicroMaps are a powerful way to display data where the display includes small, lightweight maps to provide geographical information regarding the data.  This geographical information gives clues to the relationship between the data that could lead to more insight. The SAS SG Procedures and GTL do not currently have built-in

Graph Table

A common scenario is where we have a table of multiple measures over time. Here we have a simple example of Frequency and Response by Day.  The Response is a linear function of the Frequency, as shown in the table on the left below. The  shape of the data is

Axis Thresholds

Have you ever wondered why sometimes a SGPLOT or GTL graph has markers drawn beyond the extreme tick and value on an axis and sometimes not?  And, if you prefer your graphs to always have tick values on the axis that cover the whole range of data, how can you

PharmaSUG-China 2014

The Third PharmaSUG-China conference was held in Beijing last week, and I had the pleasure to attend this excellent conference along with a record number of attendees. On Thursday, I presented two 1/2 day seminars on ODS Graphics.  One titled "Advanced Topics in GTL" and another titled "Complex Clinical Graphs

More on Spaghetti Plots

In her article Creating Spaghetti Plots Just got Easy, Lelia McConnell has provided us a glimpse into some new useful features in the SAS 9.4M2 release.  The term Spaghetti plots generally refers to cases where time series plots have to be  identified by multiple group classifications.  The support for the

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

Proportional Euler Diagram

The topic of VENN diagrams had come up a while ago.  At that time, I thought it may be interesting to build a proportional VENN diagram.  But, reading up on VENN Diagrams, I learned that VENN diagrams represent all intersections of N sets, regardless of whether there are actually any observations in one

Report from PharmaSUG 2014

Just getting back from PharmaSUG 2014 in San Diego.  The conference was great, both inside and outside.  The organizers ordered up some great weather for the Padres game and also for dinner on the flight deck of the Midway Carrier. Our focus here being on graphics, we were all extremely gratified by the presentations in

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

Multi-Group Series Plots

The series plot is a popular way to visualize response data over a continuous axis like date with a group variable like treatment.   Here is some data I made up of a response value by date, treatment, classification and company that makes the drug.  The data is simulated as shown in the attached program

Survival Plot

One of the most popular graph amongst clinical and pharmaceutical users is the Survival Plot as created from the LIFETEST Procedure.  This is one graph that users most often want to customize.  See Creating and Customizing the Kaplan-Meier Survival Plot in PROC LIFETEST - Warren F.

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

Visualize a matrix in SAS by using a discrete heat map

A heat map is a graphical representation of a matrix that uses colors to represent values in the matrix cells. Heat maps often reveal the structure of a matrix. There are three common applications of visualizing matrices with heat maps: Visualizing a correlation or covariance matrix reveals relationships between variables.

Graphs at WUSS - Part 1

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

R U Graphing with SAS?

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

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.

How to specify mosaic plot colors in SAS

The mosaic plot is a graphical visualization of a frequency table. In a previous post, I showed how to use the FREQ procedure to create a mosaic plot. This article shows how to create a mosaic plot by using the MOSAICPARM statement in the graph template language (GTL). (The MOSAICPARM

Create mosaic plots in SAS by using PROC FREQ

Mosaic plots (Hartigan and Kleiner, 1981; Friendly, 1994, JASA) are used for exploratory data analysis of categorical data. Mosaic plots have been available for decades in SAS products such as JMP, SAS/INSIGHT, and SAS/IML Studio. However, not all SAS customers have access to these specialized products, so I am pleased

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?
