有人可以看看这个,看看为什么计数不适用于第一张图表。
$(document).ready(function() {
display_chart(54,'overall');
display_chart(55,'test');
});
function display_chart(amount,div){
var paper = Raphael(document.getElementById(div), 500, 500);
paper.customAttributes.arc = function(xloc, yloc, value, total, R) {
var alpha = 360 / total * value,
a = (90 - alpha) * Math.PI / 180,
x = xloc + R * Math.cos(a),
y = yloc - R * Math.sin(a),
path;
if (total == value) {
path = [
["M", xloc, yloc - R],
["A", R, R, 0, 1, 1, xloc - 0.01, yloc - R]
];
} else {
path = [
["M", xloc, yloc - R],
["A", R, R, 0, +(alpha > 180), 1, x, y]
];
}
return {
path: path
};
};
var backCircle = paper.circle(150, 100, 70).attr({
