javascript - Chart.js 标签颜色

Question

我正在使用 chart.js 创建条形图，但似乎无法更改标签颜色或图例颜色。我想出了如何更改刻度颜色，但我不确定将“scaleFontColor”放在哪里，如果那确实是我需要使用的。

这是一个链接，指向它现在的样子。 http://imgur.com/nxaH1mk

这是我的代码:

var ctx = document.getElementById("myChart");
var myChart = new Chart(ctx, {
    scaleFontColor: "white",
    type: "bar",
    data: {
        labels: <?php echo json_encode($timeSlice); ?>, 
        datasets: [{
            label: "A Label",
            backgroundColor: "rgba(159,170,174,0.8)",
            borderWidth: 1,
            hoverBackgroundColor: "rgba(232,105,90,0.8)",
            hoverBorderColor: "orange",
            scaleStepWidth: 1,
            data: <?php echo json_encode($myCount); ?>
        }]
    },
    options: {
        legend: {
            fontColor: "white"
        },
        scales: { 
            yAxes: [{
                ticks: {
                    fontColor: "white",
                    stepSize: 1,
                    beginAtZero: true
                }
            }]
        }
    }
});

如有任何帮助，我们将不胜感激。

呃，我解决了，很抱歉这个问题。但我想我会留下答案，以防其他人遇到我的问题。

var ctx = document.getElementById("barChart");
    var myChart = new Chart(ctx, {
        type: "bar",
        data: {
            labels: ["label 1", "label 2"], 
            datasets: [{
                label: "My Label",
                backgroundColor: "rgba(159,170,174,0.8)",
                borderWidth: 1,
                hoverBackgroundColor: "rgba(232,105,90,0.8)",
                hoverBorderColor: "orange",
                scaleStepWidth: 1,
                  data: [4, 5]
            }]
        },
        options: { 
            legend: {
                labels: {
                    fontColor: "blue",
                    fontSize: 18
                }
            },
            scales: {
                yAxes: [{
                    ticks: {
                        fontColor: "green",
                        fontSize: 18,
                        stepSize: 1,
                        beginAtZero: true
                    }
                }],
                xAxes: [{
                    ticks: {
                        fontColor: "purple",
                        fontSize: 14,
                        stepSize: 1,
                        beginAtZero: true
                    }
                }]
            }
        }
    });
