<template> <div id="kline_container"></div> </template>
``<script>
import Kline from 'kline';
var kline = new Kline({
element: "#kline_container",
symbol: "BTC",
symbolName: "比特币",
type: "poll",
url: "http://192.168.0.147:80/index.php/api/index/getKline"
});
kline.draw();
export default {

data() {
return {
