我有以下代碼:如何使用自己的調色板中Plottable.js餅圖
var scale = new Plottable.Scales.Linear();
var colorScale = new Plottable.Scales.Color();
var data = [{ val: 1 }, { val: 2 }, { val: 3 },
{ val: 4 }, { val: 5 }, { val: 6 }];
var plot = new Plottable.Plots.Pie()
.addDataset(new Plottable.Dataset(data))
.sectorValue(function(d) { return d.val; }, scale)
.attr("fill", function(d) { return d.val; }, colorScale)
.renderTo("svg#example");
window.addEventListener("resize", function() {
plot.redraw();
});
<!doctype html>
<html>
<head>
<!-- Later add new CSS to define the placement of the legend, fold change etc -->
</head>
<body>
<!-- Display the sliding bar -->
<svg width="100%" height="100%" id="example"></svg>
<!-- Act on the thing -->

如果您運行的代碼,你會發現,餅圖 用默認顏色生成。
我想要做的是用我自己的調色板:
var tableau20 = ['#1F77B4', '#FF7F0E', '#2CA02C', '#D62728', '#9467BD', '#8C564B', '#CFECF9', '#7F7F7F', '#BCBD22', '#17BECF'];
我怎樣才能做到這一點?
var colorScale = new Plottable.Scales.Color(tableau20);
