这段HTML代码创建了一个雷达图，用于展示权重系数对多目标优化结果的敏感性分析。以下是代码分析和改进建议： 1. 数学计算问题： - 坐标轴计算使用了`300+250*cos(120)`这样的表达式，但JavaScript数学函数需要弧度而非角度 - 应该使用`Math.cos()`和`Math.sin()`函数，并将角度转换为弧度 修正方案： ```html <!-- 修正后的坐标轴 --> <line x1="300" y1="50" x2="300+250*Math.cos(2*Math.PI/3)" y2="300-250*Math.sin(2*Math.PI/3)" stroke="#333" stroke-width="2"/> <text x="300+250*Math.cos(2*Math.PI/3)+10" y="300-250*Math.sin(2*Math.PI/3)-10" font-family="Arial" font-size="14">碳排放</text> ``` 2. SVG标记定义缺失： - 代码中使用了`marker-end="url(#arrowhead)"`但未定义箭头标记 - 需要在SVG开头添加标记定义 修正方案： ```html <svg width="600" height="600" xmlns="http://www.w3.org/2000/svg"> <defs> <marker id="arrowhead" markerWidth="10" markerHeight="7" refX="0" refY="3.5" orient="auto"> <polygon points="0 0, 10 3.5, 0 7" fill="#333"/> </marker> </defs> <!-- 其余代码 --> </svg> ``` 3. 交互性增强建议： - 添加悬停效果显示具体数值 - 使用JavaScript动态生成数据 - 添加图例说明各颜色代表的权重方案 优化后的图例部分： ```html <div class="legend"> <div class="legend-item"> <div class="legend-color" style="background-color: #3366ff;"></div> <span>均衡权重 (1:1:1)</span> </div> <div class="legend-item"> <div class="legend-color" style="background-color: #ff3333;"></div> <span>成本优先 (5:2:3)</span> </div> <!-- 其他图例项 --> </div> ``` 三条额外需要注意的逻辑点： 1. 三角函数计算必须使用弧度制而非角度制 2. SVG标记(marker)需要先定义后使用 3. 雷达图各维度数据需要统一标准化处理才能正确比较 [2025-05-24 21:15:18 | AI写代码神器 | 568点数解答]
