Drift Chart

A chart to render a graph of daily drifts for a space. npm

Using this chart

This chart has a single default export. This exported function takes two arguments: a dom element, and an object full of properties. When called, this chart will render the chart inside the given DOM element. See the below example.

import driftChart from '@density/chart-drift';
// or: const driftChart = require('@density/chart-drift').default;

const element = document.getElementById('chart-container');
const props = {dates: [], driftChart: []};
driftChart(element, props);

In addition, if you'd like to render a chart in a context where the DOM is abstracted away from you, such as a React or Angular app, then check out our companion helper library.

Properties

• data: An array of {drift: <count at a given time>, date: <moment object representing a given day>, eventCount: <how many events happened in a given day>} objects.

  Example:

[
  {
    drift: 5,                            // A drift of 5
    date: moment().subtract(1, 'day'),   // was recorded yesterday
    eventCount: 100,                     // and there was 100 total events yesterday.
  },
  {
    drift: 1,                            // A drift of 1
    date: moment().subtract(2, 'day'),   // was recorded two days ago
    eventCount: 142,                     // and there was 142 total events two days ago.
  },
  ...
