我想用chart .js绘制一个水平条形图,但它一直在缩放图表,而不是使用我从脚本中分配的画布的高度。
有没有办法从脚本中设置图形的高度?
var ctx = $('#myChart'); ctx.height(500); var myChart = new Chart(ctx, { type: 'horizontalBar', 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 }] }, maintainAspectRatio: false, options: { scales: { yAxes: [{ ticks: { beginAtZero: true } }] } } }); <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.4.0/Chart.min.js"></script> <div class="graph"> <div class="chart-legend"> </div> <div class="chart"> <canvas id="myChart"></canvas> </div> </div>
