I apologize for not writing last month. I was buried in several workshops during August that required my attention. The workshops ended last week in August. During these workshops, I attempted to use Gnuplot to develop simple pressure graph waveforms. I could not effectively use these graphs in my presentations.
I wanted to use a fence plot layout to demonstrate the varied pressures generated by osteopaths when doing hard tissue examinations; this is a simple task using an R file.
I read Chapters 2-15 of ‘Gnuplot in Action’ by Philipp K. Janert. Each chapter was well written and focused; however the book, overall, lacked in true teaching principles for cohesive learning. For example, Chapter 2 was aimed at developing simple graphs, it gave the commands on developing a sin graph or a simple x/y plot. Yet the Chapter did not give enough details on hand collating the raw data into the correct format. If the data is incorrectly collated, then improper data plots are generated. The following chapters then assume you generated a graph, and how you can change axis names, multidata colours, etc.
Overall I could not recommend the book for a new user. This is not an instructional teaching book. It is more of a power user manual for previous Gnuplot users. The author is a data scientist, and I wonder if he wrote for this audience accidently and not for a new user. I am positive that “online forum mentoring” could be a key factor in becoming a power user of Gnuplot.
So I used R files to generate the graphs for my presentations.
I changed my distro from Fedora MATE on my work computer. A Fedora update caused a kamikaze moment on one of my R programs. I was able to revert to an older Fedora kernel, and run the program, but I decided I need greater stability. Do I revert back to Ubuntu, or another Fedora remix? I decided to stay within the realm of RPM and chose CentOS.
CentOS is known for its stability and long-term support for 10 years. It has a great online presence as a server-based OS. Many people state that CentOS is not a desktop distro, yet I am running Chromium, LibreOffice, R, Handbrake, VLC, and Kdenlive.
Next month, I will do a quick documentation on how I set up CentOS for my daily desktop use.
