JSXGraph

I found this cool graphing JS library which has a wordpress plugin! It’s called JSXGraph and is rather nifty!. Here is an example graphs showing Facebook users over time.


var brd = JXG.JSXGraph.initBoard('box',
            {boundingbox: [-50, 900, 3000, -150], 
             keepaspectratio:true, 
             axis:true, 
             grid:0, 
             showNavigation:false});

brd.suspendUpdate();

//Points for graph
var p = [];
  p[0] = brd.create('point', [0,0], {style:6,name:""});
  p[1] = brd.create('point', [1665,100], {style:6,name:"100"});
  p[2] = brd.create('point', [1890,200], {style:6,name:"200"});
  p[3] = brd.create('point', [2050,300], {style:6,name:"300"});
  p[4] = brd.create('point', [2193,400], {style:6,name:"400"});
  p[5] = brd.create('point', [2359,500], {style:6,name:"500"});
  p[6] = brd.create('point', [2527,600], {style:6,name:"600"});
  p[7] = brd.create('point', [2672,700], {style:6,name:"700"});
  p[8] = brd.create('point', [2787,800], {style:6,name:"800"});

//Line
var graph = brd.create('curve', 
              brd.neville(p),
              {strokeColor:'red',
               strokeWidth:5,
               strokeOpacity:0.5});

//Labels
xtxt = brd.create('text',[1400,-110, 'Days Online'], {fontSize:12});
ytxt = brd.create('text',[10,850, 'Millions of users'], {fontSize:12});

brd.unsuspendUpdate();

Here’s the code:


<jsxgraph width="600" height="200" box="box">
var brd = JXG.JSXGraph.initBoard('box',
            {boundingbox: [-50, 900, 3000, -150], 
             keepaspectratio:true, 
             axis:true, 
             grid:0, 
             showNavigation:false});

brd.suspendUpdate();

//Points for graph
var p = [];
  p[0] = brd.create('point', [0,0], {style:6,name:""});
  p[1] = brd.create('point', [1665,100], {style:6,name:"100"});
  p[2] = brd.create('point', [1890,200], {style:6,name:"200"});
  p[3] = brd.create('point', [2050,300], {style:6,name:"300"});
  p[4] = brd.create('point', [2193,400], {style:6,name:"400"});

  p[7] = brd.create('point', [2672,700], {style:6,name:"700"});
  p[8] = brd.create('point', [2787,800], {style:6,name:"800"});

//Line
var graph = brd.create('curve', 
              brd.neville(p),
              {strokeColor:'red',
               strokeWidth:5,
               strokeOpacity:0.5});

//Labels
xtxt = brd.create('text',[1400,-110, 'Days Online'], {fontSize:12});
ytxt = brd.create('text',[10,850, 'Millions of users'], {fontSize:12});

brd.unsuspendUpdate();
