Fine-tuning the date axis, in your bar chart

In these modern times, my utility bill has a bar chart so I can see how my current consumption compares to my historical usage. I decided to create my own version of this utility bill bar chart, and make a few improvements along the way. If you're into SGplot bar

Converting from SAS/Graph to ODS Graphics - color control

In this 'Rosetta Graph' example, I demonstrate how to control bar chart colors in Gchart and SGplot. But first, here's a little diversion... some artwork in my office here at SAS. There's a *lot* of artwork hanging around at SAS, but this particular painting wasn't created by the SAS artists

Converting from Gchart to SGpie - simple pie chart

For my third 'Rosetta Graph' example, I will focus on a simple pie chart. Hopefully this example will show you how to convert your SAS/Graph Proc Gchart pies into almost-identical Proc SGpie pies. And speaking of almost-identical pies, here are two beautiful pies my friend Beth made - which one

Plot a family of curves in SAS

A family of curves is generated by an equation that has one or more parameters. To visualize the family, you might want to display a graph that overlays four of five curves that have different parameter values, as shown to the right. The graph shows members of a family of

Converting from Gchart to SGplot - simple bar chart

You've probably heard of the famous Rosetta Stone. It had the same decree written on it in both ancient Egyptian and Greek, and was an essential key to help modern historians decipher and translate the ancient Egyptian hieroglyphs. To help the 'old timers' (like me) shift from using SAS/Graph to the

Graph wide data and long data in SAS

Statistical programmers and analysts often use two kinds of rectangular data sets, popularly known as wide data and long data. Some analytical procedures require that the data be in wide form; others require long form. (The "long format" is sometimes called "narrow" or "tall" data.) Fortunately, the statistical graphics procedures

Visualize interaction effects in regression models

Knowing how to visualize a regression model is a valuable skill. A good visualization can help you to interpret a model and understand how its predictions depend on explanatory factors in the model. Visualization is especially important in understanding interactions between factors. Recently I read about work by Jacob A.

So klappt’s mit der Migration von Business Intelligence & Co.

Business Intelligence (BI) begleitet uns schon seit geraumer Zeit – und zwar in ganz unterschiedlichen Ausprägungen. Und das Thema wird immer wichtiger und verändert sich im gleichen Maße, wie Unternehmen den Wert datengetriebener Entscheidungen erkennen. Damals und heute BI war in „jungen Jahren“ geprägt von teuren, komplexen Systemen, die sich

Gershgorin discs and the location of eigenvalues

The eigenvalues of a matrix are not easy to compute. It is remarkable, therefore, that with relatively simple mental arithmetic, you can obtain bounds for the eigenvalues of a matrix of any size. The bounds are provided by using a marvelous mathematical result known as Gershgorin's Disc Theorem. For certain

Essentials of Map Coordinate Systems and Projections in Visual Analytics

If you spend any time working with maps and spatial data, having a fundamental understanding of coordinate systems and map projections becomes necessary. It’s the foundation of how spatial data and maps work. These areas invariably evoke trepidation and some angst, even in the most seasoned map professional. And rightfully

NC tornado animation (1950-2018)

SAS Customer Intelligence 360: Factorization machines, visual analytics, and personalized marketing [Part 2]

Competition in customer experience management has never been as challenging as it is now. Customers spend more money in aggregate, but less per brand. The average size of a single purchase has decreased, partly because competitive offers are just one click away. Predicting offer relevance to potential (and existing) customers plays a

The catch phrase “everything happens somewhere” is increasingly common these days. That “somewhere” translates into a location on the Earth; a latitude and longitude. When one of these “somewhere’s” is combined with many other “somewhere’s”, you quickly have a robust spatial data set that becomes actionable with the right analytic
