更改X和Y轴字体颜色

Question

如何更改X和Y轴标签的颜色？我试图在fontColor内部使用,scaleLabel但我可能在错误的地方做它？

我试图内将其scale作为可以在源代码中找到.我也尝试过scales甚至内部xAxes.

var options = {
type: 'bar',
    data: {
        labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
        datasets: [{
            label: '# of Votes',
            data: [12, 19, 3, 5, 2, 3],
            backgroundColor: 'red',
            borderWidth: 1
        }]
    },
    options: {
        scale: {
            scaleLabel:{
                fontColor: 'red'
            }
        },
        scales: {
            yAxes: [{
                ticks: {
                    beginAtZero:true
                }
            }]
        }
    }
 };

我一直在检查文档,但对我来说似乎并不是很清楚.而由于chart.js没有提供足够的例子,有时候发现事情并不容易......

$(function(){
var ctx = document.getElementById("myChart");
//Chart.defaults.global.defaultFontColor='red';
var myChart = new Chart(ctx, {
    type: 'bar',
    data: {
        labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
        datasets: [{
            label: '# of Votes',
            data: [12, 19, 3, 5, 2, 3],
            backgroundColor: [
                'rgba(255, 99, 132, 0.2)',
                'rgba(54, 162, 235, 0.2)',
                'rgba(255, 206, 86, 0.2)',
                'rgba(75, 192, 192, 0.2)',
                'rgba(153, 102, 255, 0.2)',
                'rgba(255, 159, 64, 0.2)'
            ],
            borderColor: [
                'rgba(255,99,132,1)',
                'rgba(54, 162, 235, 1)',
                'rgba(255, 206, 86, 1)',
                'rgba(75, 192, 192, 1)',
                'rgba(153, 102, 255, 1)',
                'rgba(255, 159, 64, 1)'
            ],
            borderWidth: 1
        }]
    },
    options: {
       legend:{labels: {fontColor: 'orange'}},
      title: {
            display: true,
            fontColor: 'blue',
            text: 'Custom Chart Title'
        },
        scales: {
            yAxes: [{
                ticks: {
                    beginAtZero:true,
                    fontColor: 'red'
                },
            }],
          xAxes: [{
                ticks: {
                    fontColor: 'green'
                },
            }]
        } 
        
    }
});
});

您可以在ticks/label/legend中使用fontColor :特定轴的标签,

options: {
        legend: {
             labels: {
                  fontColor: 'orange'
                 }
              },
        title: {
            display: true,
            fontColor: 'blue',
            text: 'Custom Chart Title'
        }     ,
        scales: {
            yAxes: [{
                ticks: {
                    beginAtZero:true,
                    fontColor: 'red'
                },
            }],
          xAxes: [{
                ticks: {
                    fontColor: 'green'
                },
            }]
        } 

    }

或更改defaultFontColor以更改画布上绘制的整个文本元素的字体颜色.

 Chart.defaults.global.defaultFontColor='red';
