Distinguished Research Statistician
Warren F. Kuhfeld is a distinguished research statistician developer in SAS/STAT R&D. He received his PhD in psychometrics from UNC Chapel Hill in 1985 and joined SAS in 1987. He has used SAS since 1979 and has developed SAS procedures since 1984. Warren wrote the SAS/STAT documentation chapters "Using the Output Delivery System," "Statistical Graphics Using ODS," "ODS Graphics Template Modification," and "Customizing the Kaplan-Meier Survival Plot." He also wrote the free web books Basic ODS Graphics Examples and Advanced ODS Graphics Examples.
Can values on an axis first decrease and then increase?
By using a format, you can change the tick values and create values that range from 100 to 50 to 100 to display the probable outcome of a sporting event.
Getting started with SGPLOT - Part 13 - Style Attributes
The STYLEATTRS statement in PROC SGPLOT enables you to override colors, markers, line patterns, fill patterns, and axis break patterns in ODS styles, without requiring you to change the ODS style template.
Image backgrounds revisited
You can use SG annotation to display graphs inside of other graphs.
Advanced ODS Graphics: Unicode, tables, and graphs
You can use Unicode to display special characters in SAS output including tables and graphs. With graphs that analytical procedures produce, you might need additional steps.
Marginal model plots
Marginal model plots display the marginal relationship between the response and each predictor. You can use a SAS autocall macro, %Marginal, to display marginal model plots.
Displaying all of the output styles
Have you ever wanted to see examples of all of the output styles that SAS provides? You can run a program and look at the resulting file, styles.html. This post explains more about the styles that you will see including a discussion of attribute priority.
Advanced ODS Graphics: PROC SGPLOT, BY groups, and SG annotation
You can use PROC SGPLOT, BY variables, and a SG annotation data set together to put separate annotations into each BY group. However, you need two more steps to make it happen. This post shows all of the steps necessary to put different annotations into each graph when you have a BY variable.
Getting started with SGPLOT - Part 12 - Loess Plot
The LOESS statement in PROC SGPLOT finds a fit function while making no assumptions about the parametric form of the regression function.
Getting started with SGPLOT - Part 11 - Penalized B-Spline Plot
You can use penalized B-splines display a smooth curve through a set of data. The PBSPLINE statement fits spline models, displays the fit function(s), and optionally displays the data values.
Getting started with SGPLOT - Part 10 - Regression Plot
The REG statement fits linear regression models, displays the fit functions, and optionally displays the data values. You can fit a line or a polynomial curve. You can fit a single function or when you have a group variable, fit multiple functions.
Advanced ODS Graphics: DRAW statements (part 2)
This post provides examples of DRAW statement syntax and links to the documentation.
Advanced ODS Graphics: DRAW statements (part 1)
DRAW statements provide to GTL what SG annotation provides to the SG procedures--a way to add text, shapes, lines, and arrows to graphs.
What you need to know about the graph template and data object in PROC SGPLOT
PROC SGPLOT looks at the PROC statements, it looks at the data, and it writes a template that might depend on the data. If you want to understand how the graph is created, you need to look at the PROC SGPLOT code, the graph template and data objects that it constructs, and the final graph.
Displaying a grouped regression fit plot along with the parameter estimates
Usually, you use axis tables when there is a clear link between the rows of the axis table and the graph. I'll show how to use an axis table to create a table that is independent of the graph. This post also uses discrete attribute maps.
Advanced ODS Graphics: Processing ODS OUTPUT data sets from PROC SGPLOT
This post shows you how to run PROC SGPLOT, create smooth curves by using penalized B-splines, use ODS OUTPUT to create an output data set from PROC SGPLOT, and process it to display drop lines.
Displaying the upper or lower triangle of a correlation matrix
This post shows ways to display the upper or lower triangle of a correlation matrix. You can also use colors to show the magnitude of the correlations.
Advanced ODS Graphics: Applying the POSITION= option to scatter plots
The POSITION= option in the TEXT statement provides you with a way to position text in a variety of locations relative to a point. You can use this option to fine tune label placement in a plot primarily created by using the SCATTER statement and the DATALABEL= option.
Fun with ODS Graphics: Animating text
This post shows you how to animate text to create a message that appears one character at a time.
Advanced ODS Graphics: A deeper dive into item stores
We'll take a deeper dive into understanding item stores--the files in which compiled templates are stored--and ways in which you can access them. At the end, I will show you one of my new examples: displaying percentages in the Kaplan-Meier failure plot.
Advanced ODS Graphics: A deeper dive into documents, dynamics, and data objects
You can modify all of the components of the graphs that analytical procedures produce: the data object, graph template, and the dynamic variables. This post takes a closer look at dynamic variables (which you can see by using PROC DOCUMENT) and data objects and explores graphs that are constructed from more than one data object.
Advanced ODS Graphics: Curve labels and date axes
Curve labels in series plots can be positioned inside or outside the graph. Date variables can be specified as TYPE=LINEAR with a date format or more commonly as TYPE=DATE. Sometimes external curve labels might appear below or above the graph, particularly with TYPE=DATE axes. This post shows you ways to move them to the right of the graph.
Fun with ODS Graphics: Drawing and rotating an impossible triangle
I hope everyone has noticed some new shortcuts in Graphically Speaking. As you scroll down and look to the right, there are shortcuts for Sanjay's getting started and clinical graphs posts and one for my advanced blogs. When Sanjay asked me to make an icon for my advanced blogs, at
Advanced ODS Graphics: Two types of axis tables
Axis tables can use the SUM= option to summarize data and display means, medians, sums, and percentages. They can instead be used to display data, text, and statistics without any summarization.
Advanced ODS Graphics: Axis tables that contain special characters
This post provides a general macro that enables you to easily display special characters (Unicode) in axis table columns.
Introducing the new SAS/STAT lines plot
In PROC GLM and most other procedures that compute LS-means, mean comparisons are now displayed graphically. This makes comparisons between a large number of groups easier to interpret.
Advanced ODS Graphics: Monotonic functions
This post shows how to use PROC SGPLOT together with PROC TRANSREG to fit monotonically increasing or decreasing functions through a scatter plot.
Advanced ODS Graphics: Inserting a graph into a graph
You can use SG Annotation (and its GTL equivalent) to display one graph inside another.
Advanced ODS Graphics: Examining and processing templates
This post shows a variety of techniques including how to use PROC TEMPLATE and the SOURCE statement, PROC SGPLOT with multiple Y-axis tables, create comparable axes in two side-by-side graphs, create a broken axis, write and use a table template that wraps text, and find and display examples of certain statements in graph templates and fonts in style templates.
Fun with ODS Graphics: Eclipse animation (part 2)
This example shows how to create two coordinated range attribute maps and use them in creating an animated gif of the eclipse.
