我遇到了我认为是 pinescript 或 tradeview 本身的错误
我有一个脚本，我正在绘制多个 VWAPS
这些 vwap 上有标签，动态显示价格变化百分比需要移动才能达到目标
这里的问题是标签就像覆盖了之前的文本（附图）
初始标签未被删除。即使我有标签删除逻辑。
我相信这是一个错误的原因是它并不总是发生！它们有时效果很好。
具体来说，如果我禁用/重新启用标签，它们会完美工作，直到我更改时间范围。
我尝试了很多“修复”，但没有任何效果。
这是 MR 代码块：是的，我也尝试过 label.settext，它仍然具有完全相同的行为。

我尝试了很多方法来删除文本（如果％发生变化）并替换它，但没有任何效果。
我相信这“可能”是一个错误的原因是，如果我禁用指标中的标签并重新启用它们，它会完美地工作，直到我切换图表时间范围，我必须再次执行此操作...图像显示文本“重叠”
您无需删除旧标签并在每个栏上创建新标签，只需修改标签对象即可。这也将有助于您提高脚本的性能。
