这个代码示例展示了如何生成随机股票数据,但请注意实际应用中应使用真实数据源。如果您需要完整的金融可视化解决方案,建议使用专业库如ECharts或Highcharts。
class StockChartGenerator {
constructor(options) {
this.width = options.width || 800;
this.height = options.height || 400;
this.dataPoints = options.dataPoints || 30;
this.volatility = options.volatility || 0.5;
this.startPrice = options.startPrice || 100;
this.trend = options.trend || 0;
}
generateRandomData() {
let data = [];
let price = this.startPrice;
for(let i = 0; i < this.dataPoints; i++) {
const changePercent = (2 * Math.random() - 1) * this.volatility;
price = price * (1 + changePercent + this.trend);
const open = price;
const high = open * (1 + Math.random() * 0.02);
const low = open * (1 - Math.random() * 0.02);
const close = low + (high - low) * Math.random();
data.push({
date: new Date(Date.now() - (this.dataPoints - i) * 86400000),
open: parseFloat(open.toFixed(2)),
high: parseFloat(high.toFixed(2)),
low: parseFloat(low.toFixed(2)),
close: parseFloat(close.toFixed(2)),
volume: Math.floor(Math.random() * 1000000) + 500000
});
}
return data;
}
renderChart(containerId) {
const container = document.getElementById(containerId);
if(!container) throw new Error('Container not found');
const data = this.generateRandomData();
// 这里可以添加实际图表渲染逻辑
// 例如使用Chart.js或ECharts等库
console.log('Generated stock data:', data);
container.innerHTML = `<pre>${JSON.stringify(data, null, 2)}</pre>`;
}
}
