Missing Coordinates

Teaser Image

Implementation of a novel extension to Parallel Coordinates, introduced in the Paper:

Where did my Lines go? Visualizing Missing Data in Parallel Coordinates

presented at EuroVis 2022. Created by Alex Bäuerle, Christian van Onzenoodt, Simon der Kinderen, Jimmy Johansson Westberg, Daniel Jönsson, and Timo Ropinski.

Demo

For a demo of missing-coordinates, check out our storybook example.

Usage

First install:

npm install --save missing-coordinates

Using our Parallel Coordinates implementation is as simple as:

Plain JS

script.js

import { PC } from "./node_modules/missing-coordinates/dist/index.mjs";
// if you are using a bundler, this would be import { PC } from "missing-coordinates";

new PC({
  target: document.body,
  props: {
    data: {
      name: "sample",
      axes: [
        { name: "A", data: ["A", "A", "A", "A", "B", "B"] },
        { name: "B", data: [0.0, null, 0.4, null, 0.8, 1.0] },
        { name: "C", data: [0.0, 0.2, 0.4, 0.6, 0.8, 1.0] },
      ],
    },
  },
});
