For far too long we have been using the venerable Scatter Plot to do the work of placing text strings in the graph. For far too long we have used the Scatter Plot or the Block Plot to place axis aligned text in the graphs. It is time to
SAS 9.4 maintenance release M2 was released early in August. This release contains some exciting new features in GTL and SG Procedures. In this article, I will describe some of the new options added to the existing plot statements. Note, I will use the SG examples here, but these are
Often there are questions from users on creating histogram using a Log X axis. One such question came up this weekend, where a user wanted a histogram of her data using log axis. Before we get into her specific case, let us first clarify what we may want to see
In her article Creating Spaghetti Plots Just got Easy, Lelia McConnell has provided us a glimpse into some new useful features in the SAS 9.4M2 release. The term Spaghetti plots generally refers to cases where time series plots have to be identified by multiple group classifications. The support for the
This article is by guest contributor Lelia McConnell, SAS Tech Support.

This post could be titled something like "Everything you wanted to know about Group Order in GTL - and more." The group ordering shows up in three different ways in your graph. Assignment of attributes (color, marker symbol) to group values. Position of group values in the graph. Display of the group
