SAS Institute Inc. (“SAS”) is an American multinational developer of analytics software based in Cary, North Carolina. The company has around 14,000 employees.
SAS started as a project at North Carolina State University to create a statistical analysis system used mainly by agricultural departments at universities in the late 1960s.
SAS is the name of their software suite that can mine, alter, manage and retrieve data from a variety of sources and perform statistical analysis on it. It has more than 200 components covering areas including statistical analysis, econometrics and time series analysis, an interactive matrix language, data mining and much more.
SAS/GRAPH is a data visualization tool that lets you create effective, attention-grabbing graphs. It consists of a collection of procedures that let you produce a variety of charts, plots, 3-D scatter/surface plots, contour plots, and maps with user-defined data.
SAS is proprietary software. What are the best free and open source alternatives to SAS/GRAPH?
matplotlib is a cross-platform, data visualization and graphical plotting library for Python and its numerical extension NumPy. It’s the core on which all static plotting libraries in Python are built. It has a very active community with several toolkits that extend functionality.
Python is a general purpose programming language that uses a collection of libraries for data manipulation, visualisation and statistical analysis. Besides matplotlib, there are a wealth of high quality open source Python visualization tools such as seaborn and plotnine. Here’s an Introduction to Python for Data Science which uses plotnine.
ggplot2 is a system for declaratively creating graphics, based on The Grammar of Graphics. You provide the data, tell ggplot2 how to map variables to aesthetics, what graphical primitives to use, and it takes care of the details.
ggplot2 is an excellent R package. You can build almost any type of chart with this package. There are lots of functions to annotate graphs, customize graphs to your exact requirements, together with a set of pre-built themes.
R is a statistical programming language that can be used for data manipulation, visualisation of data and statistical analysis. The R language consists of a set of tokens and keywords and a grammar that you can use to explore and understand data from many different sources. Here’s an Introduction to R for Data Science which illustrates how to get started with ggplot2.
gnuplot plots functions and data points in both two- and three-dimensional plots in many different styles and many different output formats.
The software can also be used as a scripting language to automate generation of plots, and is designed primarily to visualize scientific data. You’ll need to invest a good chunk of time to exploit some of its advanced features.
