r - 有没有办法在绘图热图的右侧移动行标签？

Question

我想知道是否可以在热图的右侧而不是左侧移动行标签，或者这不能在绘图中移动。

data<-as.matrix(mtcars)
data[upper.tri(data)] <- NA

library(plotly)
plot_ly(x=colnames(data), y=rownames(data), z = data,colors = colorRamp(c("red","green")), type = "heatmap") %>%
  layout(
    xaxis=list(tickfont = list(size = 30), tickangle = 45),
    margin = list(l = 150, r = 50, b = 150, t = 0, pad = 4))

Answer 1

为此，我们可以使用 yaxis = list(side = "right") 并使用 colorbar = list(x = -0.4) 调整颜色条位置(您可以需要为您的特定图表稍微调整一下这个值):

plot_ly(x = colnames(data), y = rownames(data), z = data,
        colors = colorRamp(c("red","green")), 
        type = "heatmap", colorbar = list(x = -0.4)) %>%
  layout(xaxis = list(tickfont = list(size = 30), tickangle = 45), 
         yaxis = list(side = "right"), 
         margin = list(l = 150, r = 50, b = 150, t = 0, pad = 4))
