Image backgrounds

As many of the regular readers of this blog know, SGPLOT and GTL, provide extensive tools to build complex graphs by layering plot statements together.  These plots work with axes, legends and attribute maps to create graphs that can scale easily to different data. There are, however, many instances where

Simulate data from a generalized Gaussian distribution

Although statisticians often assume normally distributed errors, there are important processes for which the error distribution has a heavy tail. A well-known heavy-tailed distribution is the t distribution, but the t distribution is unsuitable for some applications because it does not have finite moments (means, variance,...) for small parameter values.

Overlay a curve on a bar chart in SAS

One of the strengths of the SGPLOT procedure in SAS is the ease with which you can overlay multiple plots on the same graph. For example, you can easily combine the SCATTER and SERIES statements to add a curve to a scatter plot. However, if you try to overlay incompatible

Marker Symbols

There has been much discussion on the SAS Communities page on usage of different symbols in a graph.  The solutioin can vary based on the SAS release.  New features have been added at SAS 9.4 releases to SG Procedures and GTL that make this very easy.  With SAS 9.4M1, almost any combination is

Layered graphs

Browsing graphs on the web, this graph caught my eye:  The Arctic Sea Ice Volume Graph.   My interest is not so much in the debate on Climate Change or Global Warming.  To me, this graph has some interesting features that can help show the benefits of plot layering to

More symbols, you say?

Users have often expressed the need for more marker symbols.  ODS Graphics supports over  30 scalable marker symbols, both filled and empty.  As mentioned in an earlier article, with SAS 9.4, filled markers can now have outlines and fills, and can also have special effects. Also with SAS 9.4, now you
