Raphael JS Pie: Add ID to path slices
I've seen this question asked over at the Raphael Google Groups, but after hours of searching there, and also on here, and Google, I cannot seem to find a solution.
I would simply like to be able to target my pie chart (svg path) slices using jQuery, but I cannot figure out how to add custom id's to the path tags - there is no ID attribute in there by default:
<path fill="#764c29" stroke="none" d="M350,350L350.6911881148345,94.00093308961084A256,256,0,0,1,561.8463375189659,206.2741175716762Z" style="stroke-width: 1; stroke-linejoin: round;" stroke-width="1" stroke-linejoin="round"/>
What would be ideal would be this:
<path **id="my_id"** fill="#764c29" stroke="none" d="M350,350L350.6911881148345,94.00093308961084A256,256,0,0,1,561.8463375189659,206.2741175716762Z" style="stroke-width: 1; stroke-linejoin: round;" stroke-width="1" stroke-linejoin="round"/>
Has anyone got an idea how this could be achieved?
This is the code I'm using to create the pie chart:
window.onload = function () {
var r = Raphael("holder");
var pie = r.g.piechart(350, 350, 256, [56, 104, 158, 23, 15, 6]);
pie.hover(function () {
this.sector.stop();
this.sector.animate({scale: [1.1, 1.1, this.cx, this.cy]}, 500, "bounce");
}, function () {
this.sector.animate({scale: [1, 1, this.cx, this.cy]}, 500, "bounce");
});
};
Essentially, the reason I need to be able to do this, is so I can create some separate anchor triggers to perform the scale animations shown above.
Any help greatly appreciated.
the piechart object provides 3 ways to reach their sectors.
1) each function
pie.each(function(sector, cover, i) {
sector.attr({/*...*/}); //raphael
$(sector.node).foo(); //jquery
});
2) series object (for styling and transforming)
var i = 0; // 0 = 56, 1 = 104, 2 = 158 …
//raphael way to hide the first sector
pie.series.items[i].attr({ opacity : 0 });
//jquery way to hide the first sector
$(pie.series.items[i].node).hide();
whereby i is the index of your data-array

3) covers object (for mouse and touch events)
//raphael way to hover the first sector
pie.covers.items[0].hover(...);
//jquery way to hover the first sector
$(pie.covers.items[0].node).hover(...);
