javascript - 如何设置带有多个环的每个切片的 jqplot donut chart 颜色？

Question

我正在尝试将颜色设置为具有多个环的 jqplot 圆环图。我需要每个切片都填充特定的颜色，如下例所示:

我在文档中读到，我需要将“varyBarColor”设置为true，并将“series”与数组一起使用许多“seriesColors”，但它只显示默认颜色。

这是我到目前为止的代码:

var s1 = [['a',8], ['b',12]]; 
var s2 = [['a',3], ['b',17]]; 
var s3 = [['a',6], ['b',14]]; 
var s4 = [['a',10], ['b',10]]; 
var s5 = [['a',2], ['b',18]];

var plot4 = $.jqplot('divId', [s1, s2, s3, s4, s5], {
    seriesDefaults: {               
        series: [
            {seriesColors: [ "#8156a1", "#000"]},
            {seriesColors: [ "#418cc8", "#ec79c0"]},
            {seriesColors: [ "#ec79c0", "#f69c44",]},
            {seriesColors: [ "#f69c44", "#fadb48"]},
            {seriesColors: [ "#fadb48", "black"]}
        ],
        renderer:$.jqplot.DonutRenderer,            
        rendererOptions:{        
            sliceMargin: 0,
            lineWidth: 0,        
            startAngle: 90,
            showDataLabels: false,
            shadowAlpha: 0,     
            ringMargin:2,               
            varyBarColor: true,             
            thickness: 7                
        }
    },
    grid: {         
        background: 'transparent',
        borderColor: 'transparent',
        shadow: false,
        drawGridLines: false,
        gridLineColor: 'transparent',
        borderWidth: '0'
    }
});

知道如何让它发挥作用吗？

提前致谢。

好吧，我设法解决了这个问题(事实上，这是一个非常愚蠢的问题)。系列值应该在 seriesDefaults 之外，而不是像我所做的那样在里面:

var plot4 = $.jqplot('divId', [s1, s2, s3, s4, s5], {
series: [
    {seriesColors: [ "#8156a1", "#000"]},
    {seriesColors: [ "#418cc8", "#ec79c0"]},
    {seriesColors: [ "#ec79c0", "#f69c44",]},
    {seriesColors: [ "#f69c44", "#fadb48"]},
    {seriesColors: [ "#fadb48", "black"]}
],
seriesDefaults: { 
    renderer:$.jqplot.DonutRenderer,            
    rendererOptions:{        
        sliceMargin: 0,
        lineWidth: 0,        
        startAngle: 90,
        showDataLabels: false,
        shadowAlpha: 0,     
        ringMargin:2,               
        varyBarColor: true,             
        thickness: 7                
    }
},
grid: {         
    background: 'transparent',
    borderColor: 'transparent',
    shadow: false,
    drawGridLines: false,
    gridLineColor: 'transparent',
    borderWidth: '0'
}

});
