Chart.js文字颜色

Question

所以即时通讯使用chart.js http://www.chartjs.org/docs/ 我无法改变底部文字的颜色

例如:"1月","2月","3月","4月","5月","6月","7月"以及左侧的数字

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

工作代码是这样的:

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

玩得开心 :)

Answer 2

在 Chart.js v3 中，可以通过以下方式实现：

Chart.defaults.color = "#ff0000";

Answer 3

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

将选项设置为以下内容：

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

如果你想改变网格线的颜色，可以找到类似的解决方案，在x / y值写入

grid: {
  color: "white"
}

Answer 4

scaleFontColor 用于更改标签的颜色.

您应该将它作为参数添加到函数中,而不是将其放在数据集中,如下所示:

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