reactjs - 如何动态调整 React chart 2 饼图的大小
问题描述
标题是动态的。号码不清楚。这就是为什么我不能给出一个固定的高度。图形越来越小。如何使图表大小动态化?
const options = {
legend: {
"position": "bottom",
align:'start',
display:true,
itemWrap: true,
},
responsive: true,
maintainAspectRatio: false,
animation: false,
};
<div className={styles['department-charts__card__altCard']}>
<Doughnut
data={doughnutData}
options={options}
/>
</div>
如果图例太多,图形会变小。使用 Legend,图表不会出现在单独的容器中。当我检查它看起来像这样
<canvas height="600" width="542" class="chartjs-render-monitor" style="display: block; height: 300px; width: 271px;"></canvas>
我希望蛋糕至少有 300 像素。使用 Legend 可以更方便地检查馅饼是否在不同的容器中。我怎样才能让这个节目充满活力?馅饼根本不会出现在小屏幕上。如果某些值中有 3 或 4,则不是问题。如果太多了,就不合适了。我不想隐藏传说
