Dynamically Add Data Points To Rickshaw Graph

So I'm using the Rickshaw graphing library and I was wondering how to dynamically add points to a graph.

I have a graph instantiated like this:

        @seriesData = [ [], [], [] ]
        random = new Rickshaw.Fixtures.RandomData(150)


        for (var i = 0; i < 50; i++) {
            random.addData(self.seriesData)
        }


        @graph = new Rickshaw.Graph(
            element: document.getElementById("chart")
            width: 550
            height: 300
            renderer: 'area'
            series: [
                {
                    color: "#c05020"
                    data: self.seriesData[0]
                    name: 'One'
                }, {
                    color: "#30c020"
                    data: self.seriesData[1]
                    name: 'Two'
                }, {
                    color: "#2791d7"
                    data: self.seriesData[2]
                    name: 'Three'
                }
            ]
        )

        @graph.render()

        hoverDetail = new Rickshaw.Graph.HoverDetail(
            graph: self.graph
        )

        legend = new Rickshaw.Graph.Legend(
            graph: self.graph
            element: document.getElementById('legend')

        )

        shelving = new Rickshaw.Graph.Behavior.Series.Toggle(
            graph: self.graph
            legend: legend
        )

        axes = new Rickshaw.Graph.Axis.Time(
            graph: self.graph
        )
        axes.render()

And I have data coming in through socket.io like this:

    app.on('data',
        (one, two, three) =>
            // Dynamically add data points to graph
    )

And I was wondering how to append these three points to the graph. I can't find any good documentation for this library. I know it's built on top of d3.js, but I'm not sure how to incorporate these methods into my graph.

Any help would be appreciated.

I envision two scenario that could solve your question:

Using the fixed Window Series for Streaming Data
leveraging the fact that arrays in javascript are passed by reference. A demo is available here

var data = [
        {
            data: [ { x: 0, y: 120 }, { x: 1, y: 890 }, { x: 2, y: 38 }, { x: 3, y: 70 }, { x: 4, y: 32 } ],
            color: "#c05020"
        }, {
            data: [ { x: 0, y: 80 }, { x: 1, y: 200 }, { x: 2, y: 100 }, { x: 3, y: 520 }, { x: 4, y: 133 } ],
            color: "#30c020"
        }
];


var graph = new Rickshaw.Graph( {
    element: document.getElementById("chart"),
    renderer: 'line',
    height: 300,
    width: 800,
    series: data
} );

var y_ticks = new Rickshaw.Graph.Axis.Y( {
    graph: graph,
    orientation: 'left',
    tickFormat: Rickshaw.Fixtures.Number.formatKMBT,
    element: document.getElementById('y_axis'),
} );

graph.render();


$('button#add').click(function() {
    data.push({
            data: [ { x: 0, y: 200 }, { x: 1, y: 390 }, { x: 2, y: 1000 }, { x: 3, y: 200 }, { x: 4, y: 230 } ],
            color: "#6060c0"
    });
    graph.update();
});
