Chart.js 文字颜色

Question

所以我正在使用 chart.js http://www.chartjs.org/docs/ 而且我无法更改底部文本的颜色

例如： "January","February","March","April","May","June","July" 和左边的数字

我尝试了所有这些选项： scaleFontColor：“#FFFFFF” pointLabelFontColor : "#FFFFFF"

我的完整代码：

<script>
    var randomScalingFactor = function(){ return Math.round(Math.random()*100)};
    var lineChartData = {
        labels : ["January","February","March","April","May","June","July"],
        datasets : [
            {
                label: "My Second dataset",
                fillColor : "rgba(255, 89, 114, 0.6)",
                strokeColor : "rgba(51, 51, 51, 1)",
                pointColor : "rgba(255, 89, 114, 1)",
                pointStrokeColor : "#fff",
                pointHighlightFill : "#fff",
                pointHighlightStroke : "rgba(151,187,205,1)",
                maintainAspectRatio: false,
                scaleFontColor: "#FFFFFF",
                pointLabelFontColor : "#FFFFFF",
                pointLabelFontSize : 30,
                data : [1,2,10,7,3,1]
            }
        ]

    }

window.onload = function(){
    var ctx = document.getElementById("canvas").getContext("2d");

    window.myLine = new Chart(ctx).Line(lineChartData, {
        responsive: true
    });
}


</script>

Answer 1

scaleFontColor用于改变标签的颜色。

与其将其放入数据集中，不如将其作为参数添加到函数中，如下所示：

window.myLine = new Chart(ctx).Line(lineChartData, {
    responsive: true, scaleFontColor: "#FFFFFF" }
});

我和凯南一起发现了这个问题

<script>
    var randomScalingFactor = function(){ return Math.round(Math.random()*100)};
    var lineChartData = {
        labels : ["January","February","March","April","May","June","July"],
        datasets : [
            {
                label: "My Second dataset",
                fillColor : "rgba(255, 89, 114, 0.6)",
                strokeColor : "rgba(51, 51, 51, 1)",
                pointColor : "rgba(255, 89, 114, 1)",
                pointStrokeColor : "#fff",
                pointHighlightFill : "#fff",
                pointHighlightStroke : "rgba(151,187,205,1)",
                maintainAspectRatio: false,
                data : [1,2,10,7,3,1]
            }
        ]

    }

    window.onload = function(){
    var ctx = document.getElementById("canvas").getContext("2d");

    window.myLine = new Chart(ctx).Line(lineChartData, {
        responsive: true, scaleFontColor: "#FFFFFF" }
)};
</script>

这不是正常的数据类型，我必须正确调整括号！

非常感谢，现在看起来很棒。

Answer 3

工作代码是这样的：

Chart.defaults.global.defaultFontColor = "#fff";

玩得开心:)

Answer 4

在 Chart.js v3 中可以通过以下方式实现：

Chart.defaults.color = "#ff0000";

Answer 5

对于 chart.js 3.x 迁移，x 轴和 y 轴上的文本标签设置如下：

设置以下选项：

scales: {
  x: {
    ticks: {
      color: "red"
    }
  },
  y: {
    ticks: {
      color: "green"
    }
  }
}

如果要更改网格线的颜色，可以找到类似的解决方案，在 x / y 值内写入

grid: {
  color: "white"
}
