- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?

示例 Highcharts - "Donut Pie"
最佳答案
似乎 Highchart 的可用颜色列表有限(只有 10 种)。
另一位用户 ( user2465233 ) 写了 work-around重复这些现有颜色,为图表中尽可能多的切片创建新颜色。
// Workaround for the lack of colors in Highcharts.getOptions().colors
// written by user2465233
var colors = [];
for (var i = 0; i < categories.length; i++) {
if (i < Highcharts.getOptions().colors.length) {
colors.push(Highcharts.getOptions().colors[i]);
} else {
colors.push(Highcharts.getOptions().colors[i - Highcharts.getOptions().colors.length]);
}
}

当然,完整的功劳归于 user2465233 。由于自 2013 年 8 月以来他/她就没有在 StackOverflow 上“见过”,我认为他/她不太可能回来发布答案。
<小时/>这是另一种更短的方法。分配颜色时,我使用 modulo operation将任何切片编号映射到可用的 HighChart 颜色。
var color_index = i>(colors.length-1) ? i%colors.length : i;
给定任何切片编号i
,这会生成一个落在可用颜色范围内的color_index
。然后,使用该 color_index
引用 HighChart 生成的 colors
数组:
var this_color = colors[color_index];
// add browser data
browserData.push({
name: categories[i],
y: data[i].y,
color: this_color
});
// add version data
drillDataLen = data[i].drilldown.data.length;
for (j = 0; j < drillDataLen; j += 1) {
brightness = 0.2 - (j / drillDataLen) / 5;
versionsData.push({
name: data[i].drilldown.categories[j],
y: data[i].drilldown.data[j],
color: Highcharts.Color(this_color).brighten(brightness).get()
});
}
在下面的代码片段中,我添加了一堆额外的切片来演示灵 active :
