Rickshaw is a JavaScript toolkit for creating interactive real-time graphs.

Getting started with a simple graph is straightforward. Here's the gist:

var graph = new Rickshaw.Graph( {
  element: document.querySelector('#graph'),
  series: [
    {
      color: 'steelblue',
      data: [ { x: 0, y: 23}, { x: 1, y: 15 }, { x: 2, y: 79 } ],
    }, {
      color: 'lightblue',
      data: [ { x: 0, y: 30}, { x: 1, y: 20 }, { x: 2, y: 64 } ],
    }
  ]
} );

graph.render();

• element: a reference to an HTML element

• series: an array of objects each with the following properties

  • name: a name meant for humans
  • color: a CSS color
  • data: an array of objects, each with x and y properties

• renderer: renderer name, like stack or line

• width: width of the graph in pixels

• height: height of graph in pixels

• interpolation: optional line smoothing / interpolation method (see D3 docs); notable options:

  • linear: straight lines between points
  • step-after: square steps from point to point
  • cardinal: smooth curves via cardinal splines (default)
  • basis: smooth curves via B-splines

• render(): paint the graph

• setRenderer(): set renderer to stack or line

• onUpdate(f): add a callback to run when the graph is rendered

• Rickshaw.Graph.Legend - add a basic legend

• Rickshaw.Graph.HoverDetail - show details on hover

• Rickshaw.Graph.JSONP - get data via a JSONP request

• Rickshaw.Graph.Annotate - add x-axis annotations

• Rickshaw.Graph.RangeSlider - dynamically zoom on the x-axis with a slider

• Rickshaw.Graph.Axis.Time - add x-axis time labels

• Rickshaw.Graph.Behavior.Series.Highlight - highlight series on legend hover

• Rickshaw.Graph.Behavior.Series.Order - reorder series in the stack with drag-and-drop

• Rickshaw.Graph.Behavior.Series.Toggle - toggle series on and off through the legend

Rickshaw comes with a few color schemes. Instantiate a palette and specify a scheme name, and then call color() on the palette to get each next color.

var palette = new Rickshaw.Color.Palette( { scheme: 'spectrum2001' } );

palette.color() // => first color in the palette
palette.color() // => next color in the palette...

Available color schemes:

• classic9
• spectrum19
• spectrum2001
• spectrum2000

Rickshaw relies on the fantastic D3 visualization library to do lots of the heavy lifting for stacking and rendering to SVG.

Some extensions require jQuery and jQuery UI, but for drawing some basic graphs you'll be okay without.

For building, we need Node and npm. Running 'make' should get you going with any luck.
