Hi Tobi,
Need you wise advice. I came across a problem. The graph won't get
displayed even when the dom being generated on qooxdoo (it is there when i
inspect with firebug). The same code inside the run function running when
put on separate plain html will work as expected.
i did include the d3.v2.min.js library in the source/index.html. Here is
the code of my first attempt,
qx.Class.define("myapplication.D3test",
{
extend: qx.ui.container.Composite,
construct: function()
{
this.base(arguments);
this.setLayout(new qx.ui.layout.VBox(5));
var canvas = new qx.ui.container.Composite(new qx.ui.layout.Grow());
var html = new qx.ui.embed.Html('<div id="d3"></div>');
canvas.add(html);
this.add(canvas);
html.addListener("appear", this._run, this);
},
members:
{
_run: function()
{
var div = d3.select('#d3');
var graph = div.append('svg:svg').attr('width',
400).attr('height', 400);
var pathinfo = [{x:0, y:60},
{x:50, y:110},
{x:90, y:70},
{x:140, y:100}];
var line = d3.svg.line()
.x(function(d){return d.x;})
.y(function(d){return d.y;})
.interpolate('linear');
graph.append('svg:path').attr('d', line(pathinfo))
.style('stroke-width', 2)
.style('stroke', 'steelblue')
.style('fill', 'none');
}
}
});
