React wrapper for Smoothie Chart

React wrapper for Smoothie Chart.

Install

npm install react-smoothie --save

Usage

var SmoothieComponent = require('react-smoothie').default;

var TestComponent = React.createClass({
  // ...

  render: function() {
    return <SmoothieComponent ref="chart" width="1000" height="300" />;
  },

  componentDidMount: function() {
    var ts1 = this.refs.chart.addTimeSeries({
      strokeStyle: 'rgba(0, 255, 0, 1)',
      fillStyle: 'rgba(0, 255, 0, 0.2)',
      lineWidth: 4,
    });
    var ts2 = this.refs.chart.addTimeSeries({
      strokeStyle: 'rgba(255, 0, 0, 1)',
      fillStyle: 'rgba(255, 0, 0, 0.2)',
      lineWidth: 4,
    });

    this.dataGenerator = setInterval(function() {
      var time = new Date().getTime();

      // Generate times slightly in the future
      time += 1000;

      ts1.append(time, Math.random());
      ts2.append(time, Math.random());
    }, 500);
  },

  componentWillUnmount: function() {
    clearInterval(this.dataGenerator);
  }
});

Props

SmoothieComponent's props are all passed as the options object to Smoothie Chart's constructor.

<SmoothieComponent ref='chart' width={1000} height={300} interpolation='step' />;

Extra

Three extra props can be used:

width

Control the width of the <canvas> used.

default: 800

height

Control the height of the <canvas> used.

default: 200

streamDelay

default: 0 (ms)

Delay the displayed chart. This value is passed after the component mounts as the second argument to SmoothieChart.streamTo.

Responsive charts

Experimental support for responsive charts was added in 0.3.0.
Simply set the responsive prop to true and canvas will use the full width of the parent container.
Height is still a controlled prop.

TimeSeries

The TimeSeries object from Smoothie Chart is exposed via the addTimeSeries() function.

The optional first argument of addTimeSeries() gets passed as the options to the TimeSeries constructor.
The last argument of addTimeSeries() gets passed as the options argument of SmoothieChart.addTimeSeries().

var ts = this.refs.chart.addTimeSeries({/* Optional TimeSeries opts */},{/* Chart.addTimeSeries opts */})

ts.append(new Date().getTime(), Math.random());
