Scalebar with background

To change the backgroundcolor, adjust the scalebgcolor variable to use the desired color. Add the following code to your preamble:

\usepackage{tikz}
\usepackage[usenames, dvipsnames]{color}
\definecolor{scalebgcolor}{rgb}{0.08,0.52,0.80}

Software for scientists

Some things takes much less time and stress once you know the right tool. Below, there is a community edited list of software for scientists.

Text editors

in General purpose text/code editors. It may be better to have a good editor for everything, than different ones for different languages, scripts, notes.

Axis

The axis is just a scene object, making it easy to manipulate and share between plots.

axis

@library_ref[example] "Axis 2D"

anthony-wang

@cell "Axis 2D" [axis] begin
    scene = Scene(@resolution)
    aviz = axis(linspace(0, 2, 4), linspace(0, 2, 4))
    center!(scene)
end

anthony-wang

@example axis
using Makie
scene = Scene(resolution = (500, 500))
aviz = axis(linspace(0, 2, 4), linspace(0, 2, 4))
center!(scene)
save("axis2d.png", scene); nothing # hide
