r - 为 Plotly 修改 y 轴上的字体大小

Question

当我尝试修改我的 y 轴标题时，它就消失了。修改 y 轴刻度就可以了。有人遇到过这个问题吗？谢谢!

library(plotly)
set.seed(2017)
x <- seq(1:10)
y <- x + rnorm(10)
plot_ly( x = ~x, y = ~y + rnorm(10)) %>%
     layout(
       xaxis = list(tickfont = list(size = 15)), 
       yaxis = list(tickfont = list(size = 25))) ## This works well.

 plot_ly( x = ~x, y = ~y + rnorm(10)) %>%
     layout(
       xaxis = list(tickfont = list(size = 15)), 
       yaxis = list(titlefont = list(size = 25))) ## This makes the y axis label disappear.

目标是修改y轴标题的大小，而不是让它一起消失。

似乎在那些情况下也有必要指定标题本身:

plot_ly( x = ~x, y = ~y + rnorm(10)) %>%
  layout(
    xaxis = list(tickfont = list(size = 15)), 
    yaxis = list(titlefont = list(size = 25), title = "test"))
