删除 Plotly 中图表之间的间隙

Question

我将图表的大小配置为闪亮但图表之间仍然有空白区域

它们显示为配置高度和宽度之前的旧区域

这是我的代码

plot1_reactive <- eventReactive(input$submit_but,{
      xaxis <- list(
                    tickformat = "%-d/%-m/%Y",
                    type='category'
                    )
      yaxis <- list(title = input$sel_par1)
      r <- plot_ly(mydata,x=date,y = a , type = 'scatter', mode = 'lines+markers'
                   , width = 950, height = 200,line = list(shape = "linear"))%>%
      layout(xaxis = xaxis, yaxis = yaxis) 

    })
    plot2_reactive <- eventReactive(input$submit_but,{
      xaxis <- list(
                    tickformat = "%-d/%-m/%Y",
                    type='category')
      yaxis <- list(title = input$sel_par2)
      r <- plot_ly(mydata,x=date,y = b , type = 'scatter', mode = 'lines+markers'
                   , width = 950, height = 200,line = list(shape = "linear"))%>%
        layout(autosize = F,xaxis = xaxis, yaxis = yaxis)  
    })

欢迎使用 Whosebug！

您需要设置 plotlyOutput (UI) 的 height 参数，而不是 plot_ly 调用（服务器）中的参数。否则将应用默认值 400px。

请参阅以下可重现示例：

library(shiny)
library(plotly)

ui <- fluidPage(
  plotlyOutput("p1Out", height = "200px"),
  plotlyOutput("p2Out", height = "200px"),
  plotlyOutput("p3Out", height = "200px")
)

server <- function(input, output, session) {
  output$p3Out <- output$p2Out <- output$p1Out <- renderPlotly({
    plot_ly(y=1:10, type = "scatter", mode = "lines+markers")
  })
}

shinyApp(ui, server)
