You can save the Gnuplot directives to a file called “base.gnuplot” and include it in other files to get the desired result for multiple charts: load "base/charts/base.gnuplot" # Replace small stripes on the Y-axis with a horizontal gridlines # Rotate X labels and get rid of the small stripes at the top (nomirror) The X label is obviously months, so we don't set it. Set terminal pngcairo nocrop enhanced font "verdana,8" size 640,300 #Gnuplot grid fullHere’s the full GnuPlot file: # Output to PNG, with Verdana 8pt font We also had to modify the grid color, because it was barely distinguishable in the Cairo render. #Gnuplot grid how toHere’s how to enable rendering with the Cairo engine: set terminal pngcairo nocrop enhanced font "verdana,8" size 640,300 The Cairo engine does a much better job of anti-aliasing the chart, which is especially important for line charts. Whether this works for you depends on if your Gnuplot was compiled with Cairo enabled. One final improvement we can make is changing the rendering engine from the default to the Cairo engine. Set title "Number of registrations per month" font ",14" tc rgb "#606060" We increase the title’s font size and color, change the range of the Y-axis from 190k-300k to 100k-300k and make the horizontal grid lines a little less pronounced. Let’s do a few small optimizations and we’ll be done. Let’s get rid of them: # Replace small stripes on the Y-axis with a horizontal gridlines See the little stripes on the Y-axis on the left and right side of the chart? Useless. ![]() This means you should remove everything that is not vital to getting your message across. Now we’re getting somewhere! One of the rules of creating nice charts is “less is more”. # Rotate X labels and get rid of the small striped at the top (nomirror) Set title "Number of registrations per month" ![]() We’ll add a title to the chart, set a label on the Y-axis and make the values on the Y-axis better readable. We’ll make them thinner and fill them in. ![]() Let’s do something about those horrid bars. Set terminal png nocrop enhanced font "verdana,8" size 640,300 The first things we’ll do is change that ugly font to something better and get rid of the text inside the graph. Maybe that looks great if you’re going for the whole sciency look, but we want something better. Plot "registrations.dat" using 2:xticlabels(1) with boxes lt rgb "#406090" Unfortunately, the defaults for Gnuplot don’t generate very appealing charts: set terminal png size 640,300 It is excellent for generating all kinds of charts. Gnuplot is a tool for plotting graphs. It was originally created to allow scientists and students to visualize mathematical functions and data interactively, but has grown to support many non-interactive uses such as web scripting.
