I have two matrices, A and B, I want to make 2 heatmaps with plotly, and overlay them
library(plotly)
A = matrix(c(1:8, rep(0, 8)), ncol = 4)
B = matrix(c(rep(0, 8), 1:8), ncol = 4)
PA <- plot_ly(z = A, type = “heatmap”, colors = colorRamp(c(“white”, “green”)))
PB <- plot_ly(z = B, type = “heatmap”, colors = colorRamp(c(“white”, “red”)))
When I try to overlay them, they are indeed overplayed, but the second heatmap totally masked the first one.
PA %>% add_trace(z = B, type = “heatmap”)
I could change the opacity in order to ‘see’ both heatmaps
PA %>% add_trace(z = B, opacity = 0.5, type = “heatmap”)
But it is really not beautiful, and I cannot set different colours for each heatmap.
Are their some elegant way to overlay them? thanks a lot.
