将曲面图中的线条删除到 x、y 和 z 平面

Question

当我在 R

中使用 plotly 绘制以下图时

library(plotly)
library(mvtnorm)
y <- x <- seq(-10, 10, length = 80)
sig <- diag(7^2, 2)
cn <-  list(c(0.0, "rgb(192,192,192)"), list(1, "rgb(0, 0, 0)"))
con <- list(
  x = list(highlight = FALSE), 
  y = list(highlight = FALSE), 
  z = list(highlight = FALSE))
dens <- matrix(dmvnorm(expand.grid(x, y), sigma = sig), ncol = length(x))
plot_ly(showscale = FALSE, color = I("black")) %>% 
  add_surface(z = dens, x = x, y = y, colorscale = cn, hoverinfo = "none",
              opacity = .9, contours = con) %>%
  layout(
    scene = list(
      xaxis=list(title = "x1", range = c(-10, 10)),
      yaxis=list(title = "x2", range = c(-10, 10)),
      zaxis=list(title = "density")), 
    plot_bgcolor = 'rgb(0, 0, 0, 0)', paper_bgcolor = 'rgba(0,0,0,0)')  %>% 
  config(displayModeBar = FALSE)

然后，当我将鼠标悬停在一个点上时，我仍然会得到一条指向 x、y 和 z 平面的线（我的鼠标位于黑色箭头上，我想删除指向红色箭头的线)

我可以删除这些行吗？如果可以，如何删除？ 我不希望鼠标悬停在图表上时发生任何事情。

正在替换

scene = list(
  xaxis = list(title = "x1", range = c(-10, 10)),
  yaxis = list(title = "x2", range = c(-10, 10)),
  zaxis = list(title = "density"))

来自

scene = list(
  xaxis = list(title = "x1", range = c(-10, 10), showspikes = FALSE),
  yaxis = list(title = "x2", range = c(-10, 10), showspikes = FALSE),
  zaxis = list(title = "density", showspikes = FALSE))

完成任务。
