'plot' 调用中的参数 'display' 无效。可能的值：[display.none、display.all]

Question

我正在编写一个 pine 脚本代码来有条件地绘制一些线条。我看到 pine 脚本 v5，plot() 函数有显示参数，但我仍然收到一个奇怪的错误。知道它可能是什么吗？

代码：

//@version=5

indicator(title="Gann Levels", shorttitle="GIL", overlay=false, timeframe="", timeframe_gaps=true)

from_previous_day_low = input.bool(title="Previous day low", defval=true)
from_previous_day_high = input.bool(title="Previous day high", defval=true)

[previous_day_high, previous_day_low] = request.security(syminfo.tickerid, "D", [high[1], low[1]])

sqrt_previous_day_low = math.round(math.sqrt(previous_day_low))
sqrt_previous_day_high = math.round(math.sqrt(previous_day_high))

display_supports() => from_previous_day_low ? display.none : display.all

display_resistances() => from_previous_day_high ? display.none : display.all


s1 = math.round(math.pow(sqrt_previous_day_high - 0.250, 2))
s2 = math.round(math.pow(sqrt_previous_day_high - 0.500, 2))
s3 = math.round(math.pow(sqrt_previous_day_high - 0.750, 2))

r1 = math.round(math.pow(sqrt_previous_day_low - 0.250, 2))
r2 = math.round(math.pow(sqrt_previous_day_low - 0.500, 2))
r3 = math.round(math.pow(sqrt_previous_day_low - 0.750, 2))

plot(series=s1, linewidth=2, color=color.new(#16F6DE, 10), display=display_supports())
plot(series=s2, linewidth=2, color=color.new(#16F6DE, 10), display=display_supports())
plot(series=s3, linewidth=2, color=color.new(#16F6DE, 10), display=display_supports())


plot(series=r1, linewidth=2, color=color.new(#16F6DE, 10), display=display_resistances())
plot(series=r2, linewidth=2, color=color.new(#16F6DE, 10), display=display_resistances())
plot(series=r3, linewidth=2, color=color.new(#16F6DE, 10), display=display_resistances())

错误：

line 26: Invalid argument 'display' in 'plot' call. Possible values: [display.none, display.all];
line 27: Invalid argument 'display' in 'plot' call. Possible values: [display.none, display.all];

您应该将条件应用于 plot() 的 series 参数。 display参数是默认启用还是禁用绘图，我相信它必须是一个常数。

您可能想将样式更改为 plot.style_circles 这样您的线路就不会接通。

plot(from_previous_day_low ? s1 : na, linewidth=2, color=color.new(#16F6DE, 10), style=plot.style_circles)
plot(from_previous_day_low ? s2 : na, linewidth=2, color=color.new(#16F6DE, 10), style=plot.style_circles)
plot(from_previous_day_low ? s3 : na, linewidth=2, color=color.new(#16F6DE, 10), style=plot.style_circles)


plot(from_previous_day_high ? r1 : na, linewidth=2, color=color.new(#16F6DE, 10), style=plot.style_circles)
plot(from_previous_day_high ? r2 : na, linewidth=2, color=color.new(#16F6DE, 10), style=plot.style_circles)
plot(from_previous_day_high ? r3 : na, linewidth=2, color=color.new(#16F6DE, 10), style=plot.style_circles)

'plot' 调用中的参数 'display' 无效。可能的值：[display.none、display.all]

Invalid argument 'display' in 'plot' call. Possible values: [display.none, display.all]
