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 long category values. That comment… Continue reading Graphs with long category values

Tips and Tricks: Managing long category values

Long category values occur frequently in real world use cases. This can happen with graphs for analysis of clinical research data, and also for graphs showing survey data where the question asked may be long (even a paragraph). Managing such long categories on the x or y axis is always a challenge. With the SAS… Continue reading Tips and Tricks: Managing long category values

Clinical graphs: Waterfall plot ++

Waterfall plots have gained in popularity as a means to visualize the change in tumor size for subjects in a study. The graph displays the reduction in tumor size in ascending order with the subjects with the most reduction on the right. Each subject is represented by a bar classified by the treatment. The type… Continue reading Clinical graphs: Waterfall plot ++

Advanced ODS Graphics: Equated Axes and the Aspect Ratio

Creating a graph that has equated axes is a subject that has been near and dear to my heart since I was in graduate school. Axes are equated when a centimeter on one axis represents the same data range as a centimeter on the other axis. Equated axes are important when displaying geometric shapes and… Continue reading Advanced ODS Graphics: Equated Axes and the Aspect Ratio

Advanced ODS Graphics: Vector plots and adjusting point labels

A vector plot draws a line (potentially ending in an arrowhead) from one point in a graph to another point. Often, that first point is the origin (0,0) although both PROC SGPLOT and the GTL enable you to specify other points. In this blog, I will show you how to pick a different origin: that… Continue reading Advanced ODS Graphics: Vector plots and adjusting point labels
