Add 'disable' property to TimeSeries for filtering

README.md

Smoothie Charts is a really small charting library designed for live streaming data. I built it to reduce the headaches I was getting from watching charts jerkily updating every second.

See http://smoothiecharts.org


Getting Started


Example

Given a <canvas>:

<canvas id="chart" width="400" height="100"></canvas>

Create a time series and chart with code resembling:

// Create a time series
var series = new TimeSeries();

// Find the canvas
var canvas = document.getElementById('chart');

// Create the chart
var chart = new SmoothieChart();
chart.addTimeSeries(series, { strokeStyle: 'rgba(0, 255, 0, 1)' });
chart.streamTo(canvas, 500);

Then, add data to your time series and it will be displayed on the chart:

// Randomly add a data point every 500ms
setInterval(function() {
    series.append(Date.now(), Math.random() * 10000);
}, 500);
