A set of helpers for matplotlib to more easily produce plots typically needed in HEP as well as style them in way that's compatible with current collaboration requirements (ROOT-like plots for CMS, ATLAS, LHCb, ALICE).

Installation

pip install mplhep

Documentation and Getting Started

A tutorial given at PyHEP 2020 is available as a binder here or you can watch the recording here.

Documentation can be found at scikit-hep.org/mplhep.

<!--- # Notes ## Consistency \& Fonts As it is ROOT does not come with any fonts and therefore relies on using system fonts. Therefore the font in a figure can be dependent on whether it was produced on OSX or PC. The default sans-serif font used is Helvetica, but it only comes with OSX, in Windows this will silently fallback to Arial. ### License Both Helvetica and Arial are proprietary, which as far as fonts go means you can use it to create any text/graphics once you have the license, but you cannot redistribute the font files as part of other software. That means we cannot just package Helvetica with this to make sure everyone has the same font in plots. Luckily for fonts it seems only the software is copyrighted, not the actual shapes, which means there are quite a few open alternatives with similar look. The most closely resembling Helvetica being Tex Gyre Heros #### Tex Gyre Heros http://www.gust.org.pl/projects/e-foundry/tex-gyre/heros You can compare yourself if the differences are meanigful below. <p float="center"> <img src="img/FontComp.png" width="400" /> </p> They are Tex Gyre Heros, Helvetica and Arial respectively. ### Math Fonts - Math fonts are a separate set from regular fonts due to the amount of special characters - It's not trivial to make sure you get a matching math font to your regular font - Most math-fonts are serif fonts, but this is not ideal if one wants to use sans-serif font for normal text like Helvetica or Arial - The number of sans-serif math-fonts is very limited - The number of **open** sans-serif math-fonts is **extremely** limited - Basically there's two, Fira Sans and GFS Neohellenic Math, of which I like Fira Sans better - https://tex.stackexchange.com/questions/374250/are-there-opentype-sans-math-fonts-under-development For consistent styling Fira Sans is included as well. #### Default Fira Sans https://github.com/mozilla/Fira #### Math font extension https://github.com/firamath/firamath --->
