如何将标签放在垂直分隔线的末尾？

Question

我用 Pine Script 编写了一个指示器，它显示工作日和周末的分隔线。除此之外，还可以显示工作日名称。

我遇到的问题是工作日标签的定位。我想将它们放在垂直分隔符的末尾线。但问题是总是有 1 个标签放错了地方。所以它总是 1 个标签放在正确的位置，在分隔线的末尾，但中间总是有 1 个是错误的。它看起来像这样： Label Problem

目前显示工作日的代码如下所示（完整代码在最后）：

low2 = hl2 - (syminfo.mintick) * i_Seplength     
label1 = label.new(x=time + 8, y=low2, text='TestMonday', xloc=xloc.bar_time, color=dot_color, textcolor=i_user_dow_color, style=label.style_circle, size=size.normal)     
array.push(createDays, label1)

有谁知道我的失败在哪里？或者还有另一种方法可以实现吗？

Answer 1

你看到了什么，问题是什么：

• 您正在使用 location.bottom 绘制工作日，因此它们位于图表中可见的最低行。
• 那么您的“TestMonday”标签条件与垂直线的条件不匹配。如果您匹配这些，您的标签也将被正确打印。要修改标签的 y 坐标，您可以使用线的低点并将其相乘，例如。减少 0.99
• 第 125 行 if array.size(createDays) > 5 在这里删除循环中的所有标签。如果您只想删除 5 之后的那些，则必须更改您的代码：
  

if array.size(createLines) > Lookback
    ln = array.shift(createLines) // remove 1st of eg. 5
    line.delete(ln) // delete it

因此，请确保您的标签和行的条件匹配以正确的方式打印具有正确的 hl2 值对于所需的 y 值（高度），并仅从数组中删除最后添加的项目而不是所有内容。
