Graphically Speaking
Data Visualization with a focus on SAS ODS Graphics
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
You can use a range attribute map to control the mapping of values in a continuous variable to colors. This post shows you how to use PROC SGPLOT to display multiple plots in the same graph and use range attribute maps.
A vector plot draws a line from one point in a graph to another point. In this post, I will show you how to create short vectors instead of vectors that emanate from the origin. I also show how to modify the positions of the vector labels.
A Stem and Leaf plot is a visual that can help quickly visualize the distribution of the data. This graph was particularly useful before the advent of modern statistical graphs including the Histogram and Box Plot. One nice feature of the plot is it shows the actual values in the
A frequently requested statistical graph is the scatter plot by with discrete categories along with mean value for each category. Searching for a "Scatter with Mean" will return a lot of requests for such a graph in SAS, Stata, R and other statistical software. Such a graph is very easy
Customizing the Kaplan-Meier plot in assorted ways is so popular that we devote an entire chapter to it in the SAS/STAT documentation.
