如何使用R给plot_ly中的子情节提供字幕 [英] How to give subtitles for subplot in plot_ly using R

问题描述

我想知道如何使用plot_ly为字幕绘制不同的字幕.请提供任何提示.在这种情况下，我获得了一个冠军BB.谢谢.

I am wondering how to give difference subtitles for the subplots using plot_ly. Any hint please. I got one title BB in this case. Thanks.

p <- subplot(
      plot_ly(economics, x = date, y = uempmed)%>%layout(showlegend = FALSE, title="AA"),
      plot_ly(economics, x = date, y = unemploy)%>%layout(showlegend = FALSE, title="BB"),
margin = 0.05
) 

推荐答案

layout中的title属性是指整个绘图表面的标题，因此只能有一个.但是，我们可以使用文本注释为您的子图创建标题"，例如:

The title attribute in layout refers to the title for the entire plotting surface, so there can only be one. However, we can use text annotations to create "titles" for your subplots, for example:

p <- subplot(
  plot_ly(economics, x = date, y = uempmed)%>%layout(showlegend = FALSE),
  plot_ly(economics, x = date, y = unemploy)%>%layout(showlegend = FALSE),
  margin = 0.05
) 
p %>% layout(annotations = list(
 list(x = 0.2 , y = 1.05, text = "AA", showarrow = F, xref='paper', yref='paper'),
  list(x = 0.8 , y = 1.05, text = "BB", showarrow = F, xref='paper', yref='paper'))
)
