断面分析功能说明：
|
<br /><br />
|
🔹 点击按钮切换状态：
|
<br />
|
- 白色：关闭拾取功能（不可选点）
|
<br />
|
- 黄色：开启拾取功能（可点击地图选择2个断面点）
|
<br /><br />
|
🔹 使用流程：
|
<br />
|
1. 点击按钮切换为黄色 ➜ 开始拾取坐标点
|
<br />
|
2. 在地图上点击选择 2 个断面点（如需修改，可重新点击）
|
<br /><br />
|
⚠️ 温馨提示：
|
<br />
|
每次只能分析一条沟渠的断面，多个断面可能导致计算异常；
|
<br />
|
使用完毕请将按钮切回白色，避免影响其他功能。

|
📌 条件限制：
|
<br />
|
仅当成功选择 2 个断面点后才可点击
|
<br /><br />
|
🔁 功能说明：
|
<br />
|
点击后将对当前断面进行分析，稍等片刻即可在图表区域查看结果

|
⚠️ 注意事项：
|
<br />
|
该功能仅支持单条沟渠分析，多个断面可能导致计算不稳定或出错

<br /><br />
|
🔁 功能说明：
|
<br />
|
点击后将移除地图上的所有断面点以及相关分析图表
|
<br /><br />
