Svg Graphael pie.js unhover事件丢失

Svg Graphael pie.js unhover事件丢失,svg,raphael,pie-chart,graphael,Svg,Raphael,Pie Chart,Graphael,由于某些奇怪的原因,Graphael并没有一个unhover事件。在pie.js中找到创建悬停事件的这段代码: chart.hover = function (fin, fout) { fout = fout || function () {}; var that = this; for (var i = 0; i < len; i++) { (function (sector, cover, j) { var o = {

    var that = this;

                sector: sector,

                cx: cx,
                cy: cy,
                mx: sector.middle.x,
                my: sector.middle.y,
                mangle: sector.mangle,

            };
            cover.mouseover(function () {
                fin.call(o);
            }).mouseout(function () {
                fout.call(o);
            });
        })(series[i], covers[i], i);
    }
    return this;
};

悬停事件具有两个函数-f_in和f_out

因此(使用我现在正在研究的示例)


明天当我破译密码的时候,一定要试试这个。我会让你知道事情的进展。
elproto.unhover = function (f_in, f_out) {
    return this.unmouseover(f_in).unmouseout(f_out);
};
pie.hover(
    // hover function
    function () {
        this.sector.stop();
        this.sector.scale(1.1, 1.1, this.cx, this.cy);
    },
    // un-hover function 
    function () {
        this.sector.scale(0.9, 0.9, this.cx, this.cy);
    }
);
