Question

作为我的Google图表代码，数据集部分中的两组数据的颜色设置相同。

如何从数据集数组中分离样式，因此样式来自一个对象或变量？

var data = {
labels: [
    new CustomLabel("January", "January 11"),
    new CustomLabel("February", "February 12"),
    new CustomLabel("March", "March 13"),
    new CustomLabel("April", "April 14"),
    new CustomLabel("May", "May 15"),
    new CustomLabel("June", "June 16"),
    new CustomLabel("July", "July 17")],
datasets: [
    {
        label: "My First dataset",
        fillColor: "rgba(220,220,220,0.2)",
        strokeColor: "rgba(220,220,220,1)",
        pointColor: "rgba(220,220,220,1)",
        pointStrokeColor: "#fff",
        pointHighlightFill: "#fff",
        pointHighlightStroke: "rgba(220,220,220,1)",
        data: [65, 59, 80, 81, 56, 55, 40]
    },
    {
        label: "My Second dataset",
        fillColor: "rgba(220,220,220,0.2)",
        strokeColor: "rgba(220,220,220,1)",
        pointColor: "rgba(220,220,220,1)",
        pointStrokeColor: "#fff",
        pointHighlightFill: "#fff",
        pointHighlightStroke: "rgba(220,220,220,1)",
        data: [28, 48, 40, 19, 86, 27, 90]
    }
]

};

如果您使用jQuery，可以使用Another SO question

var style = {
    fillColor: "rgba(220,220,220,0.2)",
    strokeColor: "rgba(220,220,220,1)",
    pointColor: "rgba(220,220,220,1)",
    pointStrokeColor: "#fff",
    pointHighlightFill: "#fff",
    pointHighlightStroke: "rgba(220,220,220,1)"
};

var data = {
    labels: [
        new CustomLabel("January", "January 11"),
        new CustomLabel("February", "February 12"),
        new CustomLabel("March", "March 13"),
        new CustomLabel("April", "April 14"),
        new CustomLabel("May", "May 15"),
        new CustomLabel("June", "June 16"),
        new CustomLabel("July", "July 17")],
    datasets: []
};

data.datasets.push($.extend({}, style, {
    label: "My First dataset",
    data: [65, 59, 80, 81, 56, 55, 40]
    })
);

data.datasets.push($.extend({}, style, {
        label: "My Second dataset",
        data: [28, 48, 40, 19, 86, 27, 90]
    })
);
