以下是条形图的模型。非常简单,除了我似乎无法使X轴上的字体大小增加。我猜想我在hAxis上做错了什么,或者只是使用了错误的选项。

<script src="Chart.Bundle.min.js" type="text/javascript"></script>

...

<canvas id="myChart" height="220" ></canvas>
<script>
    var ctx = document.getElementById("myChart").getContext('2d');
    var myChart = new Chart(ctx, {
        type: 'bar',
        data: {
            labels: ['Break','Lunch','Meeting','Aux Out','Aux In'],
            datasets: [{                    
                data: [20, 20, 20, 20, 20],
                backgroundColor: [
                    'rgba(66, 244, 98, 0.9)',
                    'rgba(101, 3, 96, 0.9)',
                    'rgba(198, 192, 194, 0.9)',
                    'rgba(43, 136, 234, 0.9)',
                    'rgba(232, 11, 55, 0.9)'

                ],
                borderColor: [
                    'rgba(57,214,86,1)',
                    'rgba(81, 2, 77, 1)',
                    'rgba(145, 140, 141, 1)',
                    'rgba(37, 118, 203, 1)',
                    'rgba(173, 8, 41, 1)'

                ],
                borderWidth: 2
            }]
        },
        options: {                          
            responsive: true,
            legend : {
                display: false,

            },
            hAxis: {
                textStyle: {
                    fontSize: 32
                }
            }
        }
    });             
    </script>
    </div>

首先,您使用的是 chart.js 而不是 google图表

对于 chart.js ,x轴标签的字体大小选项如下...

        scales: {
            xAxes: [{
                ticks: {
                    fontSize: 40
                }
            }]
        }

请参阅以下工作片段...

$(document).ready(function() {
    var ctx = document.getElementById("myChart").getContext('2d');
    var myChart = new Chart(ctx, {
        type: 'bar',
        data: {
            labels: ['Break','Lunch','Meeting','Aux Out','Aux In'],
            datasets: [{
                data: [20, 20, 20, 20, 20],
                backgroundColor: [
                    'rgba(66, 244, 98, 0.9)',
                    'rgba(101, 3, 96, 0.9)',
                    'rgba(198, 192, 194, 0.9)',
                    'rgba(43, 136, 234, 0.9)',
                    'rgba(232, 11, 55, 0.9)'

                ],
