Vue.use(VCharts) 3.我们在相应的组件中直接使用就可以了，比如说柱状图是ve-histogram，我们直接写标签即可，不需要在创建一个div容器了 <ve-histogram :data="<em>chartData</em>...right: ['orderAmount']}, labelMap: {'orderCount': '订单数量', 'orderAmount': '订单金额'} }, <em>chartData</em>...下面附上完整代码，由于异步接口无法直观的展示我们的data结构，所以我在完整代码里面用的是静态数据，方便大家更直观的查看 <ve-histogram :data="chartData..., } } 以上就是v-charts的基本用法了，上面用的是柱状图，其他例如：折线图，饼状图等等都是这样的用法，区别就是标签不一样 //折线图 //饼状图 等等这里不在一一赘述，需要的直接去看v-charts官网介绍即可。
它扩展了图表组件的逻辑, 并自动创建名为 chartData 的props参数, 并为这个参数添加vue watch....如果 mixin 渲染一个新的图表, 它将调用this.renderChart(this.chartData, this.options)....一个简单的监视器将会是这样: watch: { chartData () { this.$data...., this.options) } } 然后, 你可以把你的组件添加到父组件里 <line-chart :chartdata="chartData" :options="chartOptions"/...="chartdata" :options="options"/> import LineChart from '.

动态判断并挂载 DOM 的问题 ⭐️ 更多前端技术和知识点，搜索订阅号 JS 菌 订阅 问题复现：父组件中通过名为 source 的 prop 向子组件 Chart 传入数据 <Chart :source="<em>chartData</em>...components/Chart' export default { name: 'Home', components: { Chart }, data () { return { <em>chartData</em>...: [] } }, mounted () { setTimeout(() => { this.<em>chartData</em> = [ [89.3, 58212,...是否获取到，一旦获取到数据，马上加载 Chart 组件，这样就可以避开在组件内部调用 v-if 带来的问题： <Chart :source="chartData...], flag: false } }, methods: { getData () { setTimeout(() => { this.chartData
