Stagraph 2.0 is Available
19 January, 2018
This week we finally launched the Stagraph 2.0. The difference between versions 1.2 and 2.0 is huge. It’s so big that the documentation prepared for the previous version lost its relevance. I will work on the new documentation and tutorials in the near future.
Screenshots From Coming Stagraph 2.0
14 December, 2017
I plan to release the new Stagraph version very soon. The difference in features, functionality and workflow is amazing. If you used one of the previous versions, you will find that it is actually a new software. The basic logic of its use remains the same, it has only been extended. The following text briefly describes the basic news. Excepting functionality, the licensing model will also be changed (more at the end of post).
Stagraph Celebrates First Year
2 October, 2017
Today it’s been exactly a year since I launched publicly the first version of Stagraph – desktop software for visual data exploration and statistical graphics.

MEZonator (2) – Features
19 May, 2017
In the previous post, I described the motivation and conditions for creating an online monitoring system app for contaminated sites that is based on open source technologies. In this post I will introduce the application functionality.
MEZonator (1) – How to Build Environmental Monitoring System Based on Open Source Technologies
9 May, 2017
In this series, I would like to introduce an internal online environmental monitoring system that I’m building in my work (Geological Survey). Gradually, in several posts I will introduce the technologies, architecture and options of its practical use.
New Chapters in the User Manual
22 April, 2017
In the "How To" section I have added new chapters for Stagraph documentation. I have added texts and pictures in two chapters, namely Data Preprocessing (5) and Visualization (6).

New section of Stagraph documentation is now available.
Stagraph Quick Start Guide
11 February, 2017
Since the full documentation of the program is not yet completed, I decided to give you a quick start guide in the form of video tutorial.
Connect Stagraph to R
4 February, 2017
In Stagraph is used 32-bit R runtime in version 3.3.2. Is it possible to use newer (future) version? With higher version of ggplot2 package? How to connect Stagraph with externally installed R runtime?
Stagraph 1.1 is Available
24 January, 2017
Relatively soon, after Stagraph 1.0 release follows the update to 1.1. The reason for quick update is a new version of the ggplot2 package on which Stagraph running.
R Console in Stagraph
18 January, 2017
As mentioned earlier, all calculations and rendering of statistical graphics is done in R Runtime. This Runtime is hidden in the background. If you need to access this interface directly (custom processing, calculations ...), you can display in program built-in R Console.

19 September, 2016
Last time we introduce the Grammar of Graphics – logical definition for statistical graphics definition. Package ggplot2 represent its practical implementation in R language. All visualizations, which are formed in Stagraph, are generated using the ggplot2 package. To understand the options of the Stagraph software, ggplot2 package will be described closer.
The Grammar of Graphics
11 September, 2016
The Stagraph software is based on a deeper theory prepared by Leland Wilkinson (1999), which he called Grammar of Graphics. Grammar of Graphics is a logical construction for statistical graphics definition in a few easy steps. If you use a tool based on the Grammar of Graphics, you will find the environment and work is fundamentally different from other classical tools.
