Use a bar chart to visualize pairwise correlations

Visualizing the correlations between variables often provides insight into the relationships between variables. I've previously written about how to use a heat map to visualize a correlation matrix in SAS/IML, and Chris Hemedinger showed how to use Base SAS to visualize correlations between variables. Recently a SAS programmer asked how [...]

Graphs with long category values

A few days ago, I posted an article on displaying first N bars from a data set.  This is useful when the data is sorted by descending response, and only the first few values are significant.  There were a few interesting comments, including one that was regarding the treatment of [...]

CAS data modeling for performance

The Cloud Analytic Server (CAS for short) is SAS’ latest high-performance, scalable, in-memory analytic data server.  In this post, I’d like to discuss the CAS physical data model, i.e.what features CAS offers for data storage, and how to use them to maximize performance in CAS (and consequently SAS Visual Analytics [...]

CAS data modeling for performance was published on SAS Users.

Advanced ODS: Controlling precisely what output is displayed

PROC SGPLOT displays titles inside the graph. If you want to display a title inside the graph and a different title outside the graph, you can use the ODS LAYOUT or the GTL. The ODS LAYOUT gives you precise control over your output and enables you to... Read More

How far are you from North Korea?

With North Korea's growing missile capabilities in the news lately, I thought it would be interesting to create a map showing how far (or close) they are from other parts of the world. I first did a few searches on the Web, to see what maps are already... Read More

What is rank correlation?

When someone refers to the correlation between two variables, they are probably referring to the Pearson correlation, which is the standard statistic that is taught in elementary statistics courses. Elementary courses do not usually mention that there are other measures of correlation. Why would anyone want a different estimate of [...]

Tips and Tricks: Show first N bars

Often we have  a graph with many bars (or categories) on the x or y axis.  These categories may be sorted by descending response such as frequency of a % value.  An example with simulated data is shown below. title 'Actual Values by Name'; proc sgplot data=bars2 noborder; vbar name / [...]

So, 27 US states are farther north than Canada, eh?

With all the recent talk about some people wanting to move from the US to Canada, I got to wondering how cold, and how far north Canada is. And after a few Google searches, I was surprised to learn that 27 US states are actually farther north than the southernmost point [...]
