请在下面运行此脚本,以下R脚本提供了一个带有两个框的闪亮仪表板。我想减少两个框之间的宽度并在右边的图表中显示数据。数据应该基于我们在ggplotly函数中看到的on click事件。我猜也可以用来做这项工作。我希望代码能够在同一时间快速高效地运行。

我已经创建了一个简单的示例,说明如何使用plotly
中的耦合事件以及一些接近您需求的示例数据:
library(shiny)
library(plotly)
library(DT)
set.seed(100)
data <- data.frame(A=sample(c('a1','a2','a3'),10,replace=T),
B=1:10,
C=11:20,
D=21:30)
shinyApp(
ui = fluidPage(
plotlyOutput("trace_plot"),
DT::dataTableOutput('tbl')),
server = function(input, output) {
output$trace_plot <- renderPlotly({
plot_ly(data, x=~A,y=~B,z=~C, source = "subset") %>% add_histogram2d()})
output$tbl <- renderDataTable({
event.data <- event_data("plotly_click", source = "subset")
if(is.null(event.data) == T) return(NULL)
print(event.data[ ,c(3:4)])
})
}
)
正如您可以通过按下第一个图表看到的那样,我们在表格中获得了下面的数据子集(x和y值),您还可以使用它与主数据合并以显示时间戳等。
