Get the right information, with visual impact, to the people who need it
My blog posts focus on visual data analysis, and many of them use geographical maps. Therefore I hope you will have fun with a quick geography quiz, which I created using SAS/Graph ... And what, you might
Often there is a need to display more than one response simultaneously for a bar chart, series plot or a vector plot. SAS 9.40M3 adds the options you need to get such results using two new options COLORRESPONSE and THICKRESPONSE where applicable. The Bar Chart on the right shows the frequency
These days many devices (such as smart phone apps, Fitbits, Apple watches, dog tracking collars, car gps, hiking gps, teen/car trackers, etc) can track your location, and provide you with standard/canned ways to analyze the data. This blog post shows how I created a custom SAS map of the tracking
I read an article recently discussing how runners inevitably slow down with age, particularly after 50. Data from the New York Marathon and Boston Marathon back this up with generally flat average finishing times for ages 20-49 followed by a steady, almost exponential, increase after 50. I haven’t reached the
I just returned home from an expedition/adventure boat trip to Cuba, and Talk Like a Pirate day is coming up this Saturday - what a combination for an interesting blog! I hope you enjoy a few pictures, and a bit of data analysis on these topics! A couple of weeks ago,
...... ein Traum von einer Welt, in der wir Menschen uns die immer größer werdende Fülle von Daten zu Nutze machen können, um die richtigen Entscheidungen zu treffen - Entscheidungen, die durch analytisches Wissen gestützt werden. Jeden Tag sammeln wir Daten – man sagt, das digitale Universum verdoppelt sich alle zwei
The SGPLOT procedure provides great tools to create all kinds of graphs for all domains from business to clinical. However, every so often, we need to create visuals that are not exactly graphs, but more like flow or network diagrams, or something entirely unique. Some users may have tools to
Since our last VirtualOil update in May, oil prices have continued to take a beating. As the chart of the rolling five-year portfolio shows, much of our strip of options is now out-of-the-money and the average value per barrel of that optionality has sunk below $7. No surprise then that
Often when the data includes some extreme difference in measures or some outliers, the plot of the data points can get skewed due to the need to accommodate the extreme outliers. The bulk of the observations get squeezed into a smaller region of the plot. While this may be useful
A few weeks back I saw a couple of posts on the Communities page from users wanting to find ways to compute the area of an general polygon and also the center of the area. I felt such features likely existed somewhere in the SAS/GRAPH set of procedures, so I asked our resident
As a linguist, I am fascinated with words, their meanings and use. So when I recently saw the words “learning analytics” in a conference paper title, I started thinking about the prevalence of the word “analytics” itself. In the last decade, we have preceded “analytics” with many modifiers referring to
I recently saw an article on washingtonpost.com showing what methods are used to generate electricity in each state. The data was interesting enough that I decided to try my hand at graphing and mapping it with our SAS software. Read along to see what I kept the same, and what
The Wall Street Journal recently published a study of the top 17 medical areas (or body parts) that venture capitalist investments are likely to benefit. They used graphs to summarize the results, but "the graph guy" in me just couldn't resist trying to improve them. Did my improvements help? -
In the past few weeks, I have written two posts on SG annotation and on saving and then modifying the graphs that analytical procedures produce: Modifying dynamic variables in ODS Graphics Annotating graphs from analytical PROCs Today, I finish this series with one more post. This one shows how you
When we first released GTL and SG Procedures back with SAS 9.2, Box Plots and Bar Charts would always treat the category axis as discrete. We realized soon enough that we need to support box plots on scaled interval axes for many clinical applications, and this was added in SAS
There's a lot of buzz about Hadoop these days. I started checking into it, and there seemed to be a gazillion releases. So, being The Graph Guy, I decided to create a graph to make it a little easier to digest! During my search for Hadoop information, I found the
There's big money in professional sports these days - we're talking billions of dollars! Do you know which teams are the most valuable? The graphs in this blog will show you... I recently saw a bar chart on dadaviz.com showing the world's most valuable sports teams. It was the right kind
Why visualization? Several reasons, actually, the most compelling being that sometimes visualization literally solves the problem for you. I remember an exercise in eighth grade English class where we were asked to describe, in words only, an object set in front of us with sufficient clarity such that our classmates,
There are many ways to modify the graphs that SAS creates. Standard graph customization methods include template modification (which most people use to modify graphs that analytical procedures produce) and SG annotation (which most people use to modify graphs that procedures such as PROC SGPLOT produce). However, you can also
We all want to customize our graphs just so, and have our personal preferences. Over the past few releases SG Procedures and GTL have added options to customize the look and feel of our graphs. In this article, I will describe new ways in which you can customize your legends. We will also see some
Netzstabilität im Stromnetz Wenn wir morgens aufstehen, schalten wir das Licht an, kochen einen Kaffee und backen Brötchen auf. Wie selbstverständlich funktionieren Beleuchtung, Kaffeemaschine, Backofen und weitere Geräte, also alle Stromverbraucher zuverlässig. Der Strom kommt ja aus der Steckdose! Doch woher bekommt die Steckdose den Strom und wer sorgt für
I've heard lots of people quote statistics about marriage & divorce, but the experts don't always agree on what the data means. So I decided to run the data through a SAS graphical analysis, and see what the numbers say ... Before we get into the numbers though, let's have a
I recently saw a cool graph showing the US import/export trade deficit. But after studying it a bit, I realized I was perceiving it wrong. Follow along in this blog, to find out what the problem was, and how I redesigned the graph to avoid it. I was looking through dadaviz.com
If you are familiar with the output delivery system (ODS), then you know that you can modify the tables and graphs that analytical procedures display by modifying table and graph templates. Perhaps less familiar is the fact that you can also modify dynamic variables. Tables and graphs are constructed from
In my quest for interesting data to graph, I found some Drug Enforcement Administration (DEA) data on US domestic cannabis eradication. Does the data say anything interesting? Read on to find out! ... While doing some searches for other data, I happened across a table on the DEA website titled
Oh, how times have changed during my 20-plus years in the insurance industry. Data wasn’t a word we used much back in the 80s and 90s, unless of course you worked in those arcane and mysterious IT data centres. Even amidst the computerisation of the insurance industry in the 80s, many
SAS 9.4 Maintenance release 3 was released on July 14. The ODS Graphics procedures include many important, useful and cool features in this release, some that have been requested by you for a while. In the next few articles, I will cover some of these features. Last time I covered
There's been quite a bit of controversy about the number of undocumented immigrants in the US lately - for example, Ann Coulter claims that number is 30 million, whereas others claim it's about 11 million (readers of my blog are data-savvy, and would dig into the details of such claims,
I saw the dress photo as blue & black. If you're a female, even if we perceived the exact same color, you might might not have said 'blue & black'. That's because women have a larger color vocabulary than men, and you might have elaborated on exactly which blue and
We are all modelers. Whenever you plan, you are building a model. Whenever you imagine, you are building a model. When you create, write, paint or speak, you first build in your head a model of what you want to accomplish, and then fill in the details with words, movements
