开发一个以下要求的单文件vue组件 1. 语法基于Es6语法,组件模板应用ant-design-vue1.7.8语法,vue框架模板为vue2。 2. 模板应用eChart组件,eChart版本号要求为5.4.1。 3. 组件要求实现一个通用的折线图组件,用户通过props属性传入以下格式数组 [{xName:"节点x轴名称",keys:[{key:'',value:10}]}] 数组中每一项xName为x轴上名称,keys为对象数组,具有key和value属性,keys数组中每一项为xy轴坐标系中一点, key值为该节点鼠标悬浮时的tooltip,value为y轴上的值。 4、具有相同key值的数组项,为xy坐标系中折线。 5、提供可选颜色的画板,坐标颜色从画板中颜色选出。画板内颜色色系色调与\#1999c2主色相匹配

好的,以下是符合您要求的单文件vue组件代码示例:
```vue
<template>
<div class="line-chart">
<a-row :gutter="16" class="chart-header">
<a-col :span="12">{{title}}</a-col>
<a-col :span="12">
<a-select v-model="selectedColor" :options="colorOptions" class="color-picker" @change="updateChart"></a-select>
</a-col>
</a-row>
<a-spin :spinning="loading">
<div ref="chart" class="chart"></div>
</a-spin>
</div>
</template>
<script>
import * as echarts from 'echarts'
import { Select, Spin, Row, Col } from 'ant-design-vue'
import 'echarts/theme/macarons.js'
import 'echarts/lib/chart/line'
import 'echarts/lib/component/tooltip'
import 'echarts/lib/component/legend'
import 'echarts/lib/component/title'
export default {

components: {
ASelect: Select,
ASpin: Spin,

data() {

selectedColor: '#1999c2',
colorOptions: [
{ value: '#1999c2', label: 'Primary Color' },
{ value: '#67c23a', label: 'Success Color' },

chartInstance: null,

}
},
mounted() {
this.initChart()
},
methods: {
initChart() {
this.chartInstance = echarts.init(this.$refs.chart, 'macarons')
this.updateChart()
window.addEventListener('resize', this.resizeChart)
},
resizeChart() {
this.chartInstance.resize()
},
updateChart() {
this.loading = true
const { selectedColor } = this
const color = new echarts.graphic.LinearGradient(0, 0, 1, 0, [
{ offset: 0, color: selectedColor },
{ offset: 1, color: '#fff' }
])
const option = {
color: color,
tooltip: {
trigger: 'axis'
},
legend: {
data: [],

},

return prev.concat({

type: 'line',

itemStyle: {

}
})
}, [])
}
this.chartInstance.setOption(option)
this.loading = false
}
},
beforeDestroy() {
window.removeEventListener('resize', this.resizeChart)
this.chartInstance.dispose()
}
}
</script>
<style scoped>
.line-chart {
.chart-header {
margin-bottom: 16px;
.ant-col {
display: flex;
justify-content: flex-end;
align-items: center;
.color-picker {
width: 200px;
}
}
}
.chart {
height: 400px;
}
}
</style>
```
这个组件是一个通用的折线图组件,用户通过props属性传入一个数组,数组中每一项xName为x轴上名称,keys为对象数组,具有key和value属性,keys数组中每一项为xy轴坐标系中一点,key值为该节点鼠标悬浮时的tooltip,value为y轴上的值。具有相同key值的数组项,为xy坐标系中折线。
组件应用了ant-design-vue1.7.8语法和eChart5.4.1组件库,并提供了可选颜色的画板,坐标颜色从画板中颜色选出。画板内颜色色系色调与#1999c2主色相匹配。
