AE Timeline by Name

In my previous article on Adverse Event Timeline Graph, I wrote about how to create the AE timeline using SAS 9.2 code, using VECTOR plot and the MARKERCHAR option in SCATTER plot.  I  described a better way to place the labels at the lower end of the vectors. SAS 9.3 provides an easier way

Violin Plots

Over the past month or more, I have been in a conversation with SAS user James Marcus, on creation of some new displays for visual communication of uncertainty.  These include display of densities using a "Violin" plot, "Density Strips" and more.   With his permission, I can share some of the

Broken Y-Axis with SAS 9.2

In the previous post on Broken Y-Axis, I reviewed different ways to display data as a Bar Chart, where the response values for some categories are many orders of magnitude larger than the other values.  These tall bars force  the display of other values to be squeezed down thus making it harder to compare

Broken Y-Axis

Often we want to display data as a bar chart where a few observations have large values compared to the rest.  Comparison between the smaller values becomes hard as the small bars are squeezed by the tall bars.  Here is an example data, and a bar chart showing the data. The large values

Bar chart on interval axis

Recently, a user asked about creating a Bar Chart of Value by Date, where the dates are displayed on a scaled interval axis.   Consider this simulated data set of value by date and treatment shown below.  This data set only has one value for each date and treatment combination. We can use the VBAR statement
