@density/chart-ingress-egress v1.2.1

Ingress Egress Chart

A plot of ingresses and egresses over time. 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 ingressEgress from '@density/chart-ingress-egress';
// or: const ingressEgress = require('@density/chart-ingress-egress').default;

const element = document.getElementById('chart-container');
const props = {events: []};
ingressEgress(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

• events: An array of {countChange: <direction of count change>, timestamp: <iso 8601 timestamp or epoch>} objects.

  Example:

[
  {
    countChange: 1,                    // An ingress was recorded
    timestamp: "2017-05-04T12:51:00Z"  // on May 4th, 2017 at 12:51 UTC.
  },
  {
    countChange: -1,                   // An egress was recorded
    timestamp: "2017-05-04T12:54:00Z"  // on May 4th, 2017 at 12:54 UTC.
  },
  ...
]

• graphDurationInMin (optional): An integer representing the duration in minutes the chart should display. Events that are older than this value will not be shown.
