Have you ever been curious about your monthly water consumption and how it compares to others in your community? Recently, I had this question and decided to get ahold of my family's water usage data for analysis. Harnessing the power of data visualization, I compared my family of four's monthly [...]

Complex Layouts using the SG Procedures

Dan Heath — Sat, 10 Sep 2022 18:53:19 +0000

The Graph Template Language (GTL) is a powerful tool for creating a wide range of graphic displays. One feature GTL has is the ability to combine independent plots together into one paneled display. The SG procedures have some limited capabilities in this area; but in this post, I am going [...]

A better 3D scatter plot macro

Yinliang Wu — Tue, 12 Jul 2022 01:18:58 +0000

SAS SGPLOT already provides the necessary graphical elements for complex visualization. 3D or high-dimensional data can be easily visualized after being projected appropriately. With SAS' strong support for animation features, SAS users can create complicated 3D or high dimension visualizations quickly.

The Power of Stacking

Amazing things can be created when you start with small pieces and stack them together. Just ask Bryan Berg. He is the current world record holder for the tallest house of cards. This same principle can be applied to the SGPLOT and SGPANEL procedures. You can take the individual plot [...]

Area Bar Charts using SGPLOT

Dan Heath — Sat, 30 Apr 2022 05:42:07 +0000

The SGPLOT procedure supports a wide variety of plot types that you can use directly or combine together to create more complex graphs. Even with this flexibility, there might be times you run across a graph that you cannot create using one of the standard plot types. An "area" bar [...]

Optimizing bar label placement

Dan Heath — Sat, 23 Apr 2022 06:41:12 +0000

When creating bar charts, it is very common to display labels with the bars to make it easier to determine the bar values or to provide additional information in the chart. However, these labels can take away valuable data space, particularly if you generate a smaller-sized graph. As you see [...]

Enhancing a scatter plot

Robert Allison — Mon, 29 Nov 2021 14:41:07 +0000

A scatter plot is my go-to graph! It's what I often start with to get a feel for the data ... and I often end up using just a scatter plot. But some scatter plots are better than others ... In this blog post, I create a scatter plot of [...]

Where do Canadians live?

Robert Allison — Thu, 11 Nov 2021 14:59:34 +0000

Canada is a geographically large country, but I've heard that much of the population lives in the small southernmost sections (near the US border). I decided to use my mapping skills, and put that to the test. Follow along, and we'll see what that looks like on a map ... [...]

Where are people moving to/from in the US?

Robert Allison — Fri, 29 Oct 2021 14:18:44 +0000

With the 2020 Census numbers starting to come out, it's interesting to look at what states are gaining (or losing) people. In this example, I create a custom map similar to the ones the US Census Bureau likes to use, and plot the 10-year change in population. But before we [...]

How to (mis)label a map

Robert Allison — Fri, 22 Oct 2021 16:40:27 +0000

This blog post is mostly just a bunch of fun maps ... maps that are labeled (or mislabeled) in various ways, using fun/interesting data. I focus on the 'fun' part, but if you're not careful you might also learn a little about the various ways to add labels to maps [...]
