The ionio-illustrate package

This package implements a Cetz chart-like object for displying mass spectrometric data in Typst documents. It allows for individually styled mass peaks, callouts, titles, and mass callipers.

Getting Started

To make use of the ionio-illustrate package, you'll need to add it to your project like shown below. Make sure you are importing a version that supports your end goal.

#import "@preview/ionio-illustrate:0.3.0": *

Then, load in your mass spectrum data and pass it through to the package like so. Data should be 2D array, and by default the mass-charge ratio is in the first column, and the relative intensities are in the second column.

#let data = csv("isobutelene_epoxide.csv")

#let ms = mass-spectrum(massspec, args: (
  size: (12,6),
  range: (0,100),
)) 

#figure((ms.display)())

There are many ways to further enhance your spectrum, please check out the manual to find out how.

Roadmap

• Pass style options through to the plot (tracker: #1)
• Better placement of text depending on plot size
• Improve default step on axes
• Add support for callouts that are not immediately above their assigned peak
  • Automatically detect when two annotations are too close, and display accordingly
• Move to new Typst type system (waiting on upstream)
• Add in function for displaying skeletal structure of chemical
• Optional second axis for absolute intensity
• Add additional display functions
  • Figure out function signature for multiple data sets
  • Overlayed and shifted
  • Horizontal reflection
    • How to update existing extras?
