地块的标题 [英] Title of Subplots in Plotly

问题描述

我正在尝试在Plotly中制作一个3x3子图的网格.我正在尝试为每个子图获取标题，并在顶部获取主要标题，但似乎无法正常工作. 我看到了这个很棒的网站，但我无法似乎找到了R的等效物.

I am trying to make a grid of 3x3 subplots in Plotly. I'm trying to get titles for each subplot and a main title on the top and I can't seem to get it to work. I see this wonderful site for Python but I can't seem to find its equivalent for R.

all <- subplot(graph1, graph2, graph3, graph4, graph5, graph6, 
graph7, graph8, graph9, nrows = 3)

这给了我我想要的网格，但是在子图上没有我想要的标题:

That gave me the grid I wanted but don't have the titles I want on the subplots:

1. Graph 1 
2. Graph 2
3. Graph 3
4. Graph 4
5. Graph 5
6. Graph 6
7. Graph 7
8. Graph 8 
9. Graph 9

，默认的主标题是图9.

and the the default Main Title was Graph 9.

有人可以协助吗?

推荐答案

您可以使用ggplot +来实现.这可以解决问题:

You could use ggplot + plotly to achieve it. This does the trick:

library(ggplot2)
library(plotly)

mtcars$main1 = "title1"
mtcars$main2 = "title2"

p1 = ggplot(mtcars, aes(x = mpg, y = cyl)) + geom_point() + facet_wrap(~main1) 
p2 = ggplot(mtcars, aes(x = disp, y = hp)) + geom_point() + facet_wrap(~main2) 

plotly::subplot(p1, p2 ,nrows = 1, margin = 0.23 ) %>% layout(title ="Main title")
