Support for legends

[Lucello]

I was reading through all the posts on legends and trying to make it
work, with no luck. The links to the blogspot article no longer work,
and importing the Legend.js page and adding in the javascript code
seems to do nothing. Anyone know how to make this work?

Any help would be greatly appreciated.

Was in the same situation, so I added it to my chart-wrapping class:

LineChart.prototype.add = function (set, xval, yval) {
if (this.sets[set] == null) {
this.legend.push(set);
}
...
}

LineChart.prototype.renderLegend = function (container) {
var colorScheme = this.options.colorScheme;
var rows = [];
for (var i = 0; i < this.legend.length; i++) {
var name = this.legend[i];
var color = colorScheme[i % colorScheme.length];
var style = { float: "left", marginRight: "2px", width: "8px",
height: "8px", border: "1px solid white", background: color };
var span = MochiKit.DOM.DIV({ style: style });
rows.push(MochiKit.DOM.DIV({}, span, name));
}
MochiKit.DOM.replaceChildNodes(container, rows);
}

Cheers,
