Real-time charts for IoT using angular and Uses the official flowthings angular client for communication with server.

Install via Bower

bower install angular-flow-chart --save

Include the scripts

<script src="bower_components/Chart.js/Chart.js"></script> <!-- Chart.js -->
<script src="bower_components/angular-chart.js/dist/angular-chart.min.js"></script> <!-- Angular Chart.js -->
<script src="bower_components/flowthings-browser/dist/flowthings-browser.min.js"></script> <!-- FlowThings Browser -->
<script src="bower_components/flowthings-angular/dist/flowthings-angular.min.js"></script> <!-- FlowThings Angular -->
<script src="bower_components/angular-flow-chart/dist/angular-flow-chart.min.js"></script> <!-- Angular Flow Charts -->

Include the ngFlowChart module as a dependency to your module, alongside flowthings for the official library:

angular.module('app', ['flowthings', 'ngFlowChart'])

Configure and start flowthings service (as per official docs):

    .config(function (flowthingsProvider) {
        flowthingsProvider.options.account = '< your username >';
        flowthingsProvider.options.token = '< your token >';
    .run(function(flowthings) {

Use the <flow-chart></flow-chart> tag in your view, adding a chart plugin within:

<flow-chart flow-id="'f123...'" limit="20">
    <flow-chart-js value-properties="['temperature', 'humidity']" chart-type="line"></flow-chart-js>

Full example can be found here.

Angular Flow Chart accepts any JS chart library via a plugin. Example of a plugin using ChartJS can be found here.

Flow Chart

flowChart directive serves as a base for communication with server, initializes data and passes any incoming data to the chart. Any actual chart is handled by plugin directives transcluded within the <flow-chart></flow-chart> tag. You can add as many chart plugins as you want.


  • flowId: id of the source Flow
  • limit: max number od data points in the graph - used in initial data fetching and passed down to chart plugin

Transclusion Controller

  • Exposes limit in the controller, so it is available to transcluded charts


  • flowChart:init : fired upon initialisation, initial drops passed to subscribers
  • flowChart:newDrop : fired when new drop arrives, passing it to the subscribers

For more info on how to build chart plugin, refer to Angular Flow ChartJS Plugin.

You can’t perform that action at this time.
