我需要通过 plotly 制作一个热图来显示更多信息

Question

我希望能够制作一个 R plotly 热图，除了显示有关 z 的信息外，我还会有更多信息，这将是文本信息。

我的意思是：我有这个数据集dataset：

library(plotly)
m <- matrix(c(NA, 1,3, 2, NA, 4, 3, 0, NA), nrow = 3, ncol = 3)

fig <- plot_ly(
    x = c("Epilepsy", "PTSD", "Depression"), y = c("Dizziness", "Slowed Thinking/ Decision-making
", "Hearing/Noise Sensitivity
"),
    z = m, type = "heatmap"
)

这给了我这个输出：

但是，当我点击每个部分时我需要更多的东西我也有这个变量：

p <- matrix(c(NA, "XX","YY", "TT", NA, "ST", "PO", "IU", NA), nrow = 3, ncol = 3)

如您所见，这不是数字，它只是提供有关关联的更多信息。

Answer 1

您可以将矩阵 p 添加到 text 属性，即

fig <- plot_ly(
  x = x, 
  y = y,
  z = m, 
  type = "heatmap",
  text = p
)

完整代码

library(plotly)
m <- matrix(c(NA, 1,3, 2, NA, 4, 3, 0, NA), nrow = 3, ncol = 3)
p <- matrix(c(NA, "XX","YY", "TT", NA, "ST", "PO", "IU", NA), nrow = 3, ncol = 3)

fig <- plot_ly(
  x = x, 
  y = y,
  z = m, 
  type = "heatmap",
  text = p
)
fig
