In this chapter is introduced the core functionality of the
Stagraph software – data visualization of imported and
preprocessed datasets. Statistical graphics is in Stagraph
created otherwise than in similar programs. It's caused by
the ggplot2 package.
This R package uses the Grammar of Graphics logic to producing the data visualizations.
With the Stagraph you will be able to create
impressive charts and data visualizations very quickly and easily. Besides the basic
functionality, it is possible to extend the basic functionality through an optional R packages
and cusom R code. In this chapter, you will learn everything required for data visualization production.
Grammar of Graphics
Author of the Grammar of Graphics methodology
(Leland Wilkinson) tries to find a system (logical approach)
for data visualization definition - through simple steps (definition objects).
If you use any of the Grammar of Graphics implementations, you can create very
impressive and complex data visualizations using a small number of simple steps.
How it looks when you create data visualization using the described approach is displayed
in the following video.
In this documentation chapter is described the practical implementation of the Grammar of
Graphics in the ggplot2 package. ggplot2 package you can use in two modes. You can create your plots in the
"console mode" (write R scripts directly to R console) or in "GUI mode" (point-and-click Stagraph interface).
Using the Stagraph GUI you can start practically immediatelly. Required R scripts are created automatically, according to your steps
in application. Stagraph interface helps you in many ways. You don't need to start with R programming at first. You can understand the logic
of the ggplot2 package witout coding. Later, if the Stagraph will not meet your increased demands, you can move to the "console mode" where
are your options (of course) more extensive. Hovewer, even in the GUI mode you can create very useful and good looking plots.
