vue+echarts+map散点図を描く
23597 ワード
echartsとvueをインストールするには書かないで、echartsが持参したmapに基づいてどのように散点図を描くかを説明すれば、echartsの公式サイトではダウンロードは許可されていませんが、vueにインストールされているechartsプラグインには完全なjsファイルとjsonファイルがあり、node_modules/echarts/mapフォルダには、中国地図、世界地図、各省地図があります
1.まずvueにグローバルに登録するか、必要なページに必要なファイルを導入します.ここではグローバル登録を使用します.
2.必要な地図に必要な地図を引用する
3.地図はcanvasと同じように容器が必要です
5.必要なデータを用意して、私は公式サイトのケースのデータを使っています.
6.描画開始
1.まずvueにグローバルに登録するか、必要なページに必要なファイルを導入します.ここではグローバル登録を使用します.
//main.js
import echarts from 'echarts'
import china from 'echarts/map/json/china.json'
Vue.prototype.$echarts = echarts
2.必要な地図に必要な地図を引用する
import 'echarts/map/js/china.js'
3.地図はcanvasと同じように容器が必要です
4.初始化echatrs并添加事件监听
document.getElementById('myChart').style.height = window.screen.availHeight * 0.9 + 'px'
this.$nextTick(() => {
this.drawLine()
})
window.addEventListener('resize', () => {
this.$echarts.init(document.getElementById('myChart')).resize()
})
5.必要なデータを用意して、私は公式サイトのケースのデータを使っています.
