R 在仅有1条轨迹的绘图图表中显示右y轴

在R plotly中，我想显示一个在左右两侧都有y轴标签的单线图。我明白，但我找不到任何地方显示如何在图表上只使用1个轨迹。下面是一个基本示例-它只显示左侧的y轴，但我希望它显示在两侧：

library(plotly)
ay <- list(
  tickfont = list(color = "red"),
  overlaying = "y",
  side = "right",
  title = "second y axis"
)
fig <- plot_ly()
fig <- fig %>% add_lines(x = ~1:3, y = ~10*(1:3), name = "slope of 10")
fig <- fig %>% layout(
  title = "Double Y Axis", yaxis2 = ay,
  xaxis = list(title="x")
)

fig

library（plotly）
ay您可以在新轴中添加相同的值，如下所示：

library(plotly)
#Setup
ay <- list(
  tickfont = list(color = "red"),
  overlaying = "y",
  side = "right",
  title = "second y axis"
)
#Plot
fig <- plot_ly()
fig <- fig %>% add_lines(x = ~1:3, y = ~10*(1:3), name = "slope of 10", yaxis = "y2")
fig <- fig %>% 
  add_lines(x = ~1:3, y = ~10*(1:3), name = "slope of 10") %>%
  layout(
  title = "Double Y Axis", yaxis2 = ay,
  xaxis = list(title="x")
)

library（plotly）
#设置
唉，这对你有帮助吗：就是这样！增加透明度并关闭hoverinfo可以做到这一点
#Plot 2
fig <- plot_ly()
fig <- fig %>% add_lines(x = ~1:3, y = ~10*(1:3), name = "slope of 10", yaxis = "y2")
fig <- fig %>% 
  add_lines(x = ~1:3, y = ~10*(1:3), name = "slope of 10") %>%
  layout(
  title = "Double Y Axis", yaxis2 = ay,
  xaxis = list(title="x"),showlegend = FALSE
)
