我正在尝试使用Raphael执行以下操作:
1)缩放SVG以适合父div(在本例中为#bg
)
2)在不同情况下更改仪表的颜色......这是我迄今为止所做的,但它不起作用:
archtype.customAttributes.counter = function (counter, top) {
var motto = '';
switch(true) {
case(counter<=(top/10)):
motto = 'Very Poor !'
colour = '#BD2727'; //pretty sure this is wrong
break;
case(counter<=(5.61*top/10)):
motto = 'Poor'
colour = '#F79A38'; //pretty sure this is wrong
break;
case(counter<=(7.21*top/10)):
motto = 'Fair'
colour = '#FBDE07'; //pretty sure this is wrong
break;
case(counter<=(8.81*top/10)):
motto = 'Good'
colour = '#90C342'; //pretty sure this is wrong
break;
case(counter<=(9.61*top/10)):
motto = 'Excellent'
colour = '#1F9C4C'; //pretty sure this is wrong
break;
}
return {
counter: [counter,top],
text: Math.floor(counter) + '\n' + motto
}
}
答案 0 :(得分:1)
我希望我的回答不会太晚:
1)适合容器可能在IE上很棘手,但在Chr / FF上更容易:你必须执行以下操作(参见my responsive gauge lib):
请注意,在窗口调整大小期间调整仪表的大小在IE上更加棘手......
2)您必须在弧的属性上设置颜色,而不是计数器的属性,请参阅this fiddle。
archtype.customAttributes.arc = function(xloc, yloc, value, total, R, counter, top) {
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]
];
}
if (counter && top) {
var colour;
switch (true) {
case (counter <= (top / 10)):
colour = '#BD2727'; //pretty sure this is wrong
break;
case (counter <= (5.61 * top / 10)):
colour = '#F79A38'; //pretty sure this is wrong
break;
case (counter <= (7.21 * top / 10)):
colour = '#FBDE07'; //pretty sure this is wrong
break;
case (counter <= (8.81 * top / 10)):
colour = '#90C342'; //pretty sure this is wrong
break;
case (counter <= (9.61 * top / 10)):
colour = '#1F9C4C'; //pretty sure this is wrong
break;
}
}
var result = {
path: path
};
if (colour){
result.stroke = colour;
}
return result;
};
