K线图
原创...大约 2 分钟
Candlestick 即我们常说的 K 线图
同时支持 'candlestick' 和 'k' 这两种 'series.type'（'k' 会被自动转为 'candlestick'）
import * as echarts from "echarts";
export default {
install: (app: any) => {
app.config.globalProperties.$map = (id: any) => {
var chartDom = document.getElementById(id)!;
if (chartDom == null) {
return;
}
echarts.dispose(chartDom);
var myChart = echarts.init(chartDom, "", { width: 800, height: 500 });
var option = {
xAxis: {
type: "category",
data: ["2027-10-24", "2027-10-25", "2027-10-26", "2027-10-27"],
},
yAxis: {
type: "value",
},
series: [
{
type: "candlestick",
data: [
[20, 34, 10, 38],
[40, 35, 30, 50],
[31, 38, 33, 44],
[38, 15, 5, 42],
],
},
],
};
myChart.setOption(option);
};
},
};
上证指数
K 线图最常用的地方就是股票 K 线图，例如我们熟悉的上证指数
import * as echarts from "echarts";
export default {
install: (app: any) => {
app.config.globalProperties.$map = (id: any) => {
var chartDom = document.getElementById(id)!;
if (chartDom == null) {
return;
}
echarts.dispose(chartDom);
var myChart = echarts.init(chartDom, "", { width: 800, height: 500 });
const splitData = (rawData: any) => {
const categoryData = [];
const values = [];
for (var i = 0; i < rawData.length; i++) {
categoryData.push(rawData[i].splice(0, 1)[0]);
values.push(rawData[i]);
}
return {
categoryData: categoryData,
values: values,
};
};
const data = splitData([
