Box with Scatter Overlay

A common request we have been often hearing is for display of the distribution of data as a box plot, along with some detailed information overlaid. For example, one may have ratings data of all the hospitals in a region by different specialty, and you want to view this distribution

Parametric Bar Charts

A parametric bar chart in SG Procedure and GTL parlance is a simplified version of the regular bar chart, where the data is assumed to be summarized prior to its usage inside the SG procedures or GTL. So, multiple occurrences of the same category and / or group combination is

Box Plot with URL links

Last week I was out to the 2nd Conference on Statistical Practice in New Orleans. It was a great opportunity to meet many users of SAS, R and other software and hear about their projects in applied statistics. I will write up my feedback on this conference soon. In the

GTL Layouts

The Graph Template Language (GTL) provides you the ability to create complex graphical layouts. We have seen how to create a regular grid of cells based on one or more classification variables using the SGPANEL procedure. Each cell contains the same type of plot. This topic was covered in Dan's article on

Percent VBar

Recently a reader chimed in with a question on the Do Loop article by Rick Wicklin on how to create a bar chart with percent statistics. Rick used SAS 9.3 and the reader wanted to do the same with SAS 9.2. For the basic (non-grouped) bar chart, the process is the

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

Unicode Tick Values using GTL

Often it is desirable to use special Unicode characters for the tick value names on the axes. However, SG procedures and GTL do not support Unicode strings in SAS data sets. With SAS 9.3, the SGPLOT procedure supports annotation which does support Unicode strings. You can create an annotation data set

Bar Chart with Target and Attribute Map

A commonly requested graph is a bar chart with response and targets. With SAS 9.3, the SGPLOT procedure supports new "parametric" plot statements called HBARPARM and VBARPARM. These statements are special versions of the HBAR and VBAR statements and they expect summarized data for each category or category+group combination. Also,

Multiple Classifiers vs Small Multiples

Often we have the need to see the data by two different classifiers at the same time, as requested by a recent query on the SAS Communities page. In this example I have simulated a response over time for patients by study and treatment. We want to create series plots

Forest Plot with SAS 9.3

OK, I promise this is the last article on Forest Plots (at least for a while). In the previous article on Subgrouped Forest Plot with Font Attributes, I discussed how to use bold text for subgroup headings. I mentioned that increasing the font size would not work as it would
