Parts one and two of this series illustrate how to use gnuplot to plot a two-dimensional point graph with time-series data. This post, the third and final of the series, focuses on plotting a bar chart. The raw input data consists of the daily number of page views, and clicks for this blog from 2005 to 2014:
As the publisher of this web site, I am interested in visualizing readership growth over time. With that in mind, I set out to plot the number of page views and clicks over time. Linux is well stocked with data plotting software. This 3-part series introduces gnuplot, a command-line tool, to plot two-dimensional time-series data.

My previous post is a guide for setting up exim4, an SMTP mail server, to use Gmail as a smarthost. One reason for setting up a mail server is to redirect my local root emails to an Internet email account that I actually monitor.

My previous post explains how to backup and playback a DVD from an iso image file in the hard way - using the command line. Now, I discuss how to do it with K3b, a GUI tool. K3b is a tool from the KDE desktop environment. For Debian users, install it as follows: $ sudo apt-get install k3b Backup
This post is about how to backup and playback DVD content on a hard drive using the command line.
My earlier post shows how to change, on the fly, the font size of X terminal emulators. Besides terminal emulators, Linux provides six virtual terminals which you can bring up from X Window by pressing Control+Alt+F1 to Control+Alt+F6 keys respectively. This post explains how to adjust the font size of virtual terminals for Debian, Ubuntu, and their derivatives.
There is no shortage of Linux X Window terminal emulators. For a power user who works long hours with the terminal, it is important to know how to zoom in, that is, make the text larger. Your strained eyes will thank you for it. The table below summarizes how to increase and decrease the font size on the fly for an non-exhaustive list of terminal emulators.
