Example of using gRaphael for a simple graph

Graph.js

$(function () {
var r = Raphael("example");
var chart = r.g.linechart (
  10, 10,
	490, 180,
	[
		[1,2,3,4,5,6,7],
		[3.5,4.5,5.5,6.5,7,8]
	],
	[
		[12, 32, 23, 15, 17, 27, 22], // red line y-values
    [10, 20, 30, 25, 15, 28]      // blue line y-values
  ], 
  {
  	nostroke: false,   // lines between points are drawn
    axis: "0 0 1 1",   // draw axes on the left and bottom
    symbol: "disc",    // use a filled circle as the point symbol
    smooth: false,      // curve the lines to smooth turns on the chart
    dash: "-",         // draw the lines dashed
    colors: [
    	"#995555",       // the first line is red  
      "#555599"        // the second line is blue
    ]
	}
)
});
