May*_*ans 5 r shiny plotly ggplotly
我试图为plotly'ssubplot函数中的每个图表提供单独的标题,我发现了一篇文章,您可以使用它来扩展子图,%>% layout(title = "Main Title)但我想为每个图表提供单独的标题(我正在使用,ggtitle但只绘制最后一个标题提供(图 4)。我发现了类似的帖子为每个子图提供标题 - R Shiny但我不认为我可以facet_wrap在我的场景中。
此外 - 我想知道如何增加子图中图表之间的边距,因为它们似乎真的被压在一起了。
任何帮助表示赞赏!

正如 @Edo 已经提到的,子图标题是关于 R 的plotly api 的一个悬而未决的问题。目前我们需要使用注解。这是一个官方的例子。
该subplot函数为我们提供了一个参数margin来添加一些空间。
library(shiny)
library(plotly)
ui <- fluidPage(
sidebarPanel("This is a sidebar"),
mainPanel(plotlyOutput("myplot"))
)
server <- function(input, output, session){
output$myplot <- renderPlotly({
gg1 <- ggplotly(
ggplot(iris, aes(x=Sepal.Length, y=Sepal.Width)) +
geom_point() +
theme_minimal()
) %>% add_annotations(
text = "Plot 1",
x = 0,
y = 1,
yref = "paper",
xref = "paper",
xanchor = "left",
yanchor = "top",
yshift = 20,
showarrow = FALSE,
font = list(size = 15)
)
gg2 <- ggplotly(
ggplot(iris, aes(x=Species, y=Sepal.Length)) +
geom_boxplot() +
theme_minimal()
) %>% add_annotations(
text = "Plot 2",
x = 0,
y = 1,
yref = "paper",
xref = "paper",
xanchor = "left",
yanchor = "top",
yshift = 20,
showarrow = FALSE,
font = list(size = 15)
)
gg3 <- ggplotly(
ggplot(iris, aes(x=Petal.Width)) +
geom_histogram()
) %>% add_annotations(
text = "Plot 3",
x = 0,
y = 1,
yref = "paper",
xref = "paper",
xanchor = "left",
yanchor = "top",
yshift = 20,
showarrow = FALSE,
font = list(size = 15)
)
gg4 <- ggplotly(
ggplot(iris, aes(x=Petal.Length)) +
geom_histogram()
) %>% add_annotations(
text = "Plot 4",
x = 0,
y = 1,
yref = "paper",
xref = "paper",
xanchor = "left",
yanchor = "top",
yshift = 20,
showarrow = FALSE,
font = list(size = 15)
)
subplot(list(gg1,gg2,gg3,gg4), nrows = 2, margin = 0.06)
})
}

顺便说一句,您可以使用schema()来浏览plotly的属性。
